[0049] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0050] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0051] In the description of this application, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use.

Therefore, they should not be construed as limitations of this application.

[0052] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0053] Figure 1a and Figure 1bThis is a schematic diagram of the resonant cavity sensor provided in an embodiment of this application. Wherein, Figure 1a A cross-sectional schematic diagram of a resonant cavity sensor is shown. Figure 1b It shows Figure 1a A schematic diagram of a resonant cavity sensor with the direction Sp oriented along the center. (See diagram below.) Figure 1a and Figure 1b As shown, the resonant cavity sensor may include: a housing cavity 130, a microwave resonant cavity 110, and a microwave detector 120.

[0054] In this embodiment, the microwave resonant cavity 110 includes a first connection end, a second connection end, and a channel connecting the first connection end and the second connection end; the receiving cavity 130 is disposed in the channel.

[0055] The cavity 130 can be used to contain the substance to be tested.

[0056] The microwave detector 120 can be used to receive and detect the resonant signal within the microwave resonant cavity 110 based on sending a microwave signal to the microwave resonant cavity 110; wherein the resonant signal is used to detect the content of the substance to be tested.

[0057] Taking an oil-water mixture as an example, this resonant signal can be used to determine the water content in the oil-water mixture.

[0058] In this embodiment, the microwave detector 120 may include a microwave transmitter and a microwave receiver. The microwave transmitter can be used to transmit microwave signals, and the microwave receiver can be used to receive microwave signals.

[0059] For example, when the analyte contains multiple substances, the content of one or more of these substances can be tested. For instance, the analyte can be an oil-water mixture, and the resonant signal can be used to detect the oil content, water content, etc., in the analyte. The analyte can be a substance whose water content needs to be determined. For example, the analyte can be tobacco, pharmaceuticals, food, etc.

[0060] Different substances, varying percentages of components within the analyte, and different forms of the analyte will all lead to differences in the signals generated within the microwave resonant cavity 110, resulting in differences in the signals received by the microwave receiver. These differences can be used to determine the content of the analyte.

[0061] The first connecting end is provided with a first connecting part 141, and the second connecting end is provided with a second connecting part 142; the first connecting part 141 and the second connecting part 142 are configured to connect to an external pipe.

[0062] exist Figure 1a and Figure 1bIn the example shown, the microwave resonant cavity 110 of the resonant cavity sensor is a hollow cylinder, meaning that the cross-section of the microwave resonant cavity 110 is annular, and the receiving cavity 130 is a cylindrical channel. Of course, depending on the needs of different actual scenarios, the microwave resonant cavity 110 can also be designed in other shapes.

[0063] In the resonant cavity sensor provided in the above embodiments, the resonant cavity sensor can calculate and determine the content of each substance in the substance to be tested based on the different detected resonant signals.

[0064] like Figures 2a to 2d As shown, this application also provides a material measuring device. Figures 2a to 2d As shown, the material measuring device may include: a first pipe 210, a second pipe 220, and a resonant cavity sensor.

[0065] The first pipe 210 is connected to the first connection part 141 of the resonant cavity sensor, and the second pipe 220 is connected to the second connection part 142 in the resonant cavity sensor.

[0066] Optionally, the first pipe 210 can be fixedly connected to the first connection part 141 of the resonant cavity sensor, and the second pipe 220 can be fixedly connected to the second connection part 142 of the resonant cavity sensor.

[0067] Optionally, the first conduit 210 is detachably connected to the first connection portion 141 of the resonant cavity sensor. The second conduit 220 can also be detachably connected to the second connection portion 142 in the resonant cavity sensor.

[0068] In this embodiment, the cross-sections of the first pipe 210 and the second pipe 220 can be circular or square.

[0069] To improve the reliability and accuracy of the material measuring device, the first pipe 210 is sealed to the first connection part 141 of the resonant cavity sensor, and the second pipe 220 and the second connection part 142 can also be sealed to each other.

[0070] Optionally, the first pipe 210 and the first connection portion 141 of the resonant cavity sensor can be connected by a clamp. For example, the connection portion between the first pipe 210 and the first connection portion 141 of the resonant cavity sensor forms a groove, and a flexible sealing gasket is sandwiched in the middle of the pipe, and the connection is fixed by a clamp.

[0071] Optionally, the connection between the first pipe 210 and the first connecting part 141 can be sealed using a filler material. For example, graphite or polytetrafluoroethylene (PTFE) braided filler can be filled into the gap between the first pipe 210 and the first connecting part 141, and then fasteners can be used to tighten the filler. These fasteners can be gland bolts, etc.

[0072] Optionally, the first pipe 210 may be provided with a flange, and the first connection part 141 may also be a flange. The space between the two flanges may be filled by a structure such as a gasket, and the two flange structures may be fastened together by bolts and nuts.

[0073] Optionally, the shape of the port of the first pipe 210 can fit with the shape of the port of the first connecting part 141, so that when the port of the first pipe 210 contacts the port of the first connecting part 141, the port of the first pipe 210 and the port of the first connecting part 141 can be fitted together. For example, the port of the first pipe 210 and the port of the first connecting part 141 can be further sealed using a fluid sealing material such as sealant.

[0074] In this embodiment, the connection method between the second pipe 220 and the second connecting part 142 can be similar to the connection method between the first pipe 210 and the first connecting part 141. For example, the connection can also be achieved by the above-mentioned connection methods.

[0075] In practical applications, the appropriate connection method can be selected based on the on-site environment. For example, if the environment requires long-term continuous monitoring of substance content, a relatively fixed connection method that does not require disassembly can be used, such as using sealant to achieve a sealed connection. On the other hand, if the object being monitored may contain highly polluting or corrosive substances, and occasional component replacement may be necessary, a connection method that allows for easy disassembly can be used.

[0076] The first pipe 210 includes a pipe of equal diameter or a flared pipe, and the second pipe 220 includes a pipe of equal diameter or a flared pipe. For example... Figures 2a to 2d As shown, in Figure 2a In the example shown, both the first pipe 210 and the second pipe 220 are pipes of equal diameter; Figure 2b In the example shown, the first pipe 210 is a trumpet-shaped pipe, and the second pipes 220 are both equal-diameter pipes; Figure 2c In the example shown, the first pipe 210 is a pipe of constant diameter, and the second pipes 220 are both flared pipes; in Figure 2d In the example shown, both the first pipe 210 and the second pipe 220 are funnel-shaped pipes. It is understood that... Figures 2a to 2dFor illustrative purposes only, the flared opening of the flared pipe can be larger or smaller depending on actual needs, and the angle between the flared section and the constant diameter section can also be set as needed. The shapes of the flared sections of the first pipe 210 and the second pipe 220 can also be different. For example, the size of the opening of the flared section of the first pipe 210 and the second pipe 220 can be different, and the angle between the flared section and the constant diameter section can also be different.

[0077] A funnel-shaped pipe can be understood as a pipe that includes at least one funnel-shaped section. Figures 2b to 2d The example shown illustrates a flared pipe with a single flared section.

[0078] Optionally, both the first pipe 210 and the second pipe 220 can be pipes of equal diameter. The diameters of the first pipe 210 and the second pipe 220 can be the same or different.

[0079] Optionally, both the first pipe 210 and the second pipe 220 can be funnel-shaped pipes. The pressure formed when the same flow rate of the analyte flows through the opening of the funnel-shaped pipe is different from that when it flows through the closing of the funnel-shaped pipe.

[0080] Optionally, one of the first pipe 210 and the second pipe 220 may be a pipe of equal diameter, and the other may be a flared pipe. For example, the first pipe 210 may be a flared pipe, and the second pipe 220 may be a pipe of equal diameter.

[0081] In practical applications, the shape of the trumpet-shaped pipe can be chosen in various ways, such as... Figures 3a to 3c As shown.

[0082] Figure 3a A schematic diagram of the first pipe 210, which is a flared pipe with a Lo-Loss pipe structure, is shown. Figure 3b and Figure 3c A schematic diagram of the first conduit 210, which is a flared conduit in the form of a nozzle, is shown. Figure 3b and Figure 3c In the example shown, the conduit may comprise four parts: an inlet plane portion, a constriction portion, a throat, and a protective groove. The inlet plane portion can be used to connect to an external conduit, and the protective groove can be used to connect to the first connection portion 141 of the resonant cavity sensor. Figure 3b and Figure 3c The difference between the examples shown is the curvature of the nozzle.

[0083] Optionally, the first conduit 210 can also be a curved conduit. The first conduit 210 can be an arc-shaped conduit. Figure 3dIn the example shown, the angle of the curved pipe is 90°. The cross-sectional shape of the curved pipe can be circular, square, etc. In this example, point P1 is the high-pressure location, and point P2 is the low-pressure location. The pressure difference can be determined based on the positions of points P1 and P2.

[0084] To facilitate the detection of the state within the material measuring device, the material measuring device may also be equipped with a fluid dynamics sensor 230.

[0085] The fluid dynamics sensor 230 can be used to detect fluid dynamics parameters within the material measuring device. These fluid dynamics parameters may include pressure data and velocity data of the substance being measured.

[0086] The aforementioned resonant signal and fluid dynamic parameters are used to determine the content and flow rate of the substance to be measured.

[0087] Optionally, the fluid dynamics sensor 230 can be disposed in the space connecting the first pipe 210, the second pipe 220 and the resonant cavity sensor, and is used to measure the fluid dynamics parameters.

[0088] Optionally, the fluid dynamics sensor 230 can be a pressure sensor, differential pressure sensor, velocity sensor, etc.

[0089] In one embodiment, the first pipe 210 may be a horn-shaped pipe, and the opening at the first end of the first pipe 210 connected to the first connection portion 141 of the resonant cavity sensor is smaller than the opening at the second end of the first pipe 210.

[0090] Optionally, the fluid dynamics sensor 230 may include a pressure sensor. At least one pressure sensor is disposed in the first pipe 210 for measuring pressure data in the first pipe 210.

[0091] Optionally, the material measuring device can be equipped with multiple pressure sensors for measuring pressure data at different locations. For example, the material measuring device can be used to measure fluids, and the pressure sensors can be positioned upstream of the fluid flow within the material measuring device.

[0092] Optionally, the fluid dynamics sensor 230 may also include a differential pressure sensor, which can be used to measure the differential pressure at at least two locations on the side where the first connection end of the resonant cavity sensor is located; wherein the pipe diameters at the two locations are different. The difference in pipe diameter may be caused by the first pipe connected to the first connection end of the resonant cavity sensor having different pipe diameters at at least two locations. The difference in pipe diameter may also be caused by the first pipe connected to the first connection end being provided with a flow obstruction element 250, resulting in different spaces through which substances can pass at at least two locations. Alternatively, the substance measuring device may be equipped with an orifice plate, the constriction orifice of which has a different diameter than that of the first pipe 210.

[0093] For example, it may include multiple differential pressure sensors.

[0094] One of the differential pressure sensors can be used to measure the pressure difference at at least two locations on the side where the first connection end of the resonant cavity sensor is located, where the pipe diameters at the two locations are different. Taking the first pipe 210 as an example, if the pipe diameters at the first location and the second location of the first pipe 210 are different, one of the differential pressure sensors can be used to measure the pressure difference between the first location and the second location of the first pipe 210.

[0095] Another differential pressure sensor can be used to measure the pressure difference between the inlet and outlet sections of a material measuring device.

[0096] In this embodiment, the artificially high gas flow rate in the substance to be measured can be determined by combining differential pressure data.

[0097] Furthermore, the airflow rate is calculated by combining the virtual height model with the aforementioned virtual height airflow rate.

[0098] When the content of various substances in the analyte varies, its density data will differ, and the resulting pressure difference will also differ for the same flow rate. Therefore, in the above implementation method, pressure data can be combined to detect the content, concentration, or flow rate of the analyte, making the measured data more accurate.

[0099] In one implementation method, see the following document for details. Figure 2d As shown, the first pipe 210 can be a trumpet-shaped pipe, and the second pipe 220 can also be a trumpet-shaped pipe.

[0100] like Figure 4 As shown, the first conduit 210 may include an inlet section 211, a constriction section 212, and a throat 213; the constriction section 212 is connected between the inlet section 211 and the throat 213, and the diameter of the inlet section 211 is longer than the diameter of the throat 213; wherein, the throat 213 is connected to the first connection part 141 of the resonant cavity sensor.

[0101] The second conduit 220 includes a diffuser section 221 and an outlet section 222, the diameter of which is longer than that of the throat 213; wherein, the diffuser section 221 is connected to the second connection portion 142 of the resonant cavity sensor.

[0102] Optionally, the second conduit 220 may also be provided with a throat, which is located between the diffuser section 221 and the resonant cavity sensor.

[0103] The aforementioned microwave resonant cavity 110 can be installed at the throat 213 of the first conduit 210.

[0104] In this embodiment, the inlet section 211 of the first pipe 210 can be connected to the flow pipe of the substance to be measured, and the outlet section 222 of the second pipe 220 can be connected to the flow pipe of the substance to be measured. For example, this substance measuring device can be used to measure the water content in oil in an oil field, and the inlet section 211 of the first pipe 210 and the outlet section 222 of the second pipe 220 can be connected at a certain location in the oil extraction pipeline of the oil field.

[0105] In the above implementation, the pipe diameters of the inlet section 211 and outlet section 222 are designed based on actual measurement scenarios to adapt to measurement and installation needs in more scenarios. Furthermore, both the first pipe 210 and the second pipe 220 are multi-segment designs, and each segment can have different pipe diameters. The first pipe 210 can have a gradually decreasing diameter, which reduces the rate at which the analyte enters the material measuring device and causes a pressure drop, improving the safety of the material measuring device. Conversely, the second pipe 220 can have a gradually increasing diameter, ensuring that the analyte does not rapidly depressurize when flowing out of the material measuring device, further improving equipment safety. Additionally, it reduces permanent pressure loss, thereby reducing the need for a more energy-intensive and powerful power source.

[0106] In one implementation, such as Figure 5 As shown, the first pipe 210 includes a first flared section 214 and a second flared section 215; the second pipe 220 is a pipe of equal diameter.

[0107] Optionally, the diameter of the second pipe 220 may be the same as the diameter at the outlet of the second horn section 215.

[0108] The first horn segment 214 is connected to the second horn segment 215, and the diameter of the connection between the first horn segment 214 and the second horn segment 215 is smaller than the diameter of other parts of the first horn segment 214, and the diameter of the connection between the first horn segment 214 and the second horn segment 215 is smaller than the diameter of other parts of the second horn segment 215.

[0109] In this embodiment, the two horn-shaped sections can generate a larger differential pressure and less pressure loss, but require a longer upstream straight pipe section. In this implementation, in order to enable the analyte to better adapt to the pressure difference formed in the first pipe 210, the first pipe 210 can be further equipped with a section of equal diameter pipe, so that the analyte can better adapt to pressure changes, and the first pipe 210 can also better adapt to the pressure changes caused by the entry of the analyte.

[0110] In one embodiment, a shrink plate may be provided between the first conduit 210 and the resonant cavity sensor.

[0111] like Figure 6 As shown, the shrink plate has shrink holes, and the size of one end of the shrink hole is different from that of the other end. Figure 6 In the example shown, the shrinkage orifice has a constant diameter section on the left and a gradually increasing diameter section on the right.

[0112] The contraction hole, the first pipe 210, the second pipe 220, and the first connection end to the second connection end of the resonant cavity sensor are connected.

[0113] For example, the opening size at one end of the contraction orifice can be smaller than the opening size of the first pipe 210. The contraction orifice can be coaxial with the first pipe 210 or not coaxial with it. The contraction orifice can also be coaxial with the receiving cavity 130 of the resonant cavity sensor or not coaxial with it.

[0114] Optionally, the shape of the shrinkage orifice can be set to other shapes as needed, as long as the diameter of the shrinkage orifice is smaller than that of the first pipe 210. For example, the shrinkage orifice can be circular, crescent-shaped, or other shapes.

[0115] Optionally, the shrink plate can be clamped between the first pipe 210 and the resonant cavity sensor. In one example, it can be clamped between the first pipe 210 and the resonant cavity sensor via flanges on both sides. To improve the sealing of the shrink hole, the first pipe 210, the second pipe 220, and the channel connecting the first connection end to the second connection end of the resonant cavity sensor, cushioning elements such as gaskets can be provided on both sides of the shrink plate to improve the sealing of the connection.

[0116] In this embodiment, the first conduit 210 is not directly connected to the first connection end of the resonant cavity sensor.

[0117] For example, the shrinkage plate can be a concentric right-angle orifice plate 240, a quarter-circle orifice plate 240, a conical inlet orifice plate 240, a segmental orifice plate 240, an eccentric orifice plate 240, a double orifice plate 240, a wear-resistant orifice plate 240, or a balancing orifice plate 240. Of course, the shrinkage plate can also be other irregular structures that can achieve the formation of a pressure difference.

[0118] In the above implementation method, pressure difference can be achieved within the material measuring device with fewer structures.

[0119] In the above implementation, the pressure difference between different positions of the analyte in the pipe can be achieved by adjusting the pipe diameter. In other scenarios, such as when the pipe is already designed and it is inconvenient to directly change the pipe diameter, a flow obstruction element 250 can be installed inside the first pipe 210 to adjust the available pipe diameter in the first pipe 210. For example, the pipe diameter of the first pipe 210 itself does not change, but a flow obstruction element 250 is installed inside the first pipe 210. This flow obstruction element 250 hinders the flow of the analyte in the first pipe 210, resulting in less flow space in the first pipe 210, thus adjusting the pipe diameter inside the first pipe 210.

[0120] Optionally, such as Figure 7a As shown, the flow obstruction 250 may include a wedge-shaped device disposed inside the first conduit 210. Exemplarily, the wedge-shaped device may conform to the inner wall of the first conduit 210. Optionally, as... Figure 7b As shown, the flow obstruction element 250 can be a spindle body, which is disposed inside the first conduit 210. Optionally, as... Figure 7c As shown, the flow obstruction element 250 can be a conical device, which can be disposed within the first pipe 210. The conical device can include a cone and a support structure for the cone. The conical device can be inserted into the pipe, therefore, it can be directly inserted into any position within the pipe of the material measuring device.

[0121] Optionally, the flow obstruction element can be a valve. This valve controls the flow diameter of the first pipe 210. By limiting the flow diameter of the first pipe 210, flow control is achieved. It can also act as a flow obstruction element to generate differential pressure for flow measurement.

[0122] For example, the valve can block a portion of the diameter of the first pipe 210. The flowable diameter of the first pipe 210 is achieved by blocking a portion of the diameter of the first pipe 210.

[0123] Optionally, such as Figure 7d As shown, the flow obstruction element can be a baffle, which, together with the first pipe 210, forms an averaging pitot tube. Due to the action of the baffle, a pressure difference can be formed upstream and downstream of the baffle in the first pipe 210. Figure 7d The example shown also illustrates a fluid dynamics sensor 230 and an insertion mechanism that connects the stop and the fluid dynamics sensor 230. Figure 7d The fluid dynamics sensor 230 shown can be a pressure sensor.

[0124] In the above implementation, a pressure difference is created by installing a flow-blocking element in the first pipe 210. Depending on the actual site environment or the amount of pressure difference, a flow-blocking element can also be installed in the second pipe 220 to create a pressure difference at different locations within the second pipe 220. The structure and form of the flow-blocking element in the second pipe 220 can be similar to those in the first pipe 210, and will not be elaborated further here.

[0125] By means of the above implementation, a pressure difference can be formed without changing the general shape of the first pipe 210 and the second pipe 220.

[0126] Depending on the calculation method, the required data for the analyte can also differ. For example, the content and flow rate of each substance in the analyte can be measured based on the velocity-related data of the analyte within the channel of the material measuring device and the water content. The fluid dynamics sensor 230 may include a velocity sensor, which is installed within a defined range at the connection between the first pipe 210 and the microwave detector 120, and / or within a defined range at the connection between the second pipe 220 and the microwave detector 120.

[0127] For example, the velocity sensor can be an inertial measurement unit (IMU), which can measure data such as acceleration and angular velocity of multiphase material flowing in a pipe.

[0128] For example, the inertial measurement unit can be suspended inside the second pipe 220. When the substance to be measured flows inside the second pipe 220, the inertial measurement unit can rotate under the action of the flow force of the substance to be measured.

[0129] In this embodiment, a swirl starter can also be provided. When it is necessary to use an inertial measurement unit to measure the speed, the swirl starter can be used in conjunction with the swirl starter to realize the speed measurement of the substance to be measured.

[0130] Alternatively, the number of speed sensors can be at least two.

[0131] Optionally, the velocity sensor can be housed within a smooth container, which can be spherical, ellipsoidal, tubular, etc. One of the smooth containers housing the velocity sensor can be suspended at a position between the center of the bore in the second pipe 220 and the pipe wall.

[0132] Optionally, the smooth container can be suspended at a position between the center of the orifice of the second pipe 220 and the pipe wall. Taking a circular cross-section of the second pipe 220 as an example, the spherical container can be suspended at a position between the center of the second pipe 220 and the pipe wall. The cross-section of the second pipe 220 can be perpendicular to the flow direction of the substance to be measured.

[0133] Alternatively, another speed sensor can be mounted inside a smooth container. This smooth container can be suspended at another location on the second pipe 220. The installation location of this other speed sensor can be outside the center of the second pipe 220.

[0134] By installing velocity sensors at different locations in the second pipe 220, the velocity sensors can measure the flow velocity at different locations. This provides a more comprehensive view of the flow velocity at different locations within the channel of the material measuring device, enabling more accurate measurement of data such as the content and flow rate of the material based on the flow velocity at each location.

[0135] To facilitate the direct calculation of relevant data, the material measuring device can also be equipped with a processing unit.

[0136] The processing unit can be connected to the microwave detector 120 and the fluid dynamics sensor 230; it can obtain the data detected by the microwave detector 120 and the fluid dynamics sensor 230. The processing unit can be used to calculate the flow rate of each phase in the fluid based on the resonant signal and fluid dynamics parameters.

[0137] Optionally, the processing unit can be an integrated circuit chip with signal processing capabilities. The aforementioned processing unit can be a general-purpose processor, including a Central Processing Unit (CPU), a Network Processor (NP), etc.; it can also be a digital signal processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. It can implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of this application. The general-purpose processor can be a microprocessor or any conventional processor.

[0138] Optionally, the processing unit may also be an electronic terminal containing a processor. The electronic terminal can obtain data detected by the microwave detector 120 and the fluid dynamics sensor 230. The processing unit then performs calculations based on the obtained data to obtain the flow rate and content of each substance in the substance to be tested.

[0139] By setting up a processing unit, the collected data can be directly calculated, reducing the traffic and time required for remote interaction and improving the efficiency of obtaining results.

[0140] In this embodiment, to gain a more comprehensive understanding of the substance to be measured by the material measuring device, the fluid dynamics sensor 230 includes a differential pressure sensor, which is used to detect the pressure difference between multiple designated locations within the material measuring device.

[0141] Optionally, a differential pressure sensor may be installed in the first pipe 210 and / or the second pipe 220 to detect the differential pressure at at least two locations in the first pipe 210 and / or the second pipe 220.

[0142] The material measuring device can be equipped with multiple differential pressure sensors to measure the pressure difference between multiple sets of locations. For example, one differential pressure sensor can measure the pressure difference between two locations in the first pipe 210, or the pressure difference between two locations in the second pipe 220. Another sensor can measure the pressure difference between the inlet and outlet of the material measuring device.

[0143] Optionally, the differential pressure sensor may include a first differential pressure sensor and a second differential pressure sensor;

[0144] The first differential pressure sensor is used to detect the pressure difference between two locations with different orifice diameters in the first pipe 210; the second differential pressure sensor is used to detect the pressure difference between the inlet and outlet ends of the material measuring device.

[0145] For multiphase fluids, especially those containing multiple immiscible substances, the flow pattern can exhibit various forms. Measuring some flow patterns is challenging and can result in significant measurement errors. Therefore, this material measuring device may further include a flow pattern shaping structure for adjusting the flow pattern of the analyte entering the device.

[0146] Optionally, the flow pattern shaping structure may include one or more of the following: a guide vane, a swirl generator, and a rectifier.

[0147] For example, the guide vane can be installed near the inlet end of the material measuring device, and the vortex generator can also be installed near the inlet end, wherein the guide vane can be mounted on the vortex generator. The rectifier can be installed near the outlet end of the material measuring device.

[0148] For example, the first pipe 210 can be a flared pipe, and the swivel can be installed inside the first pipe 210.

[0149] Depending on the specific application scenario, this material measuring device can also include more detection components. For example, to facilitate the measurement of the temperature of the substance being measured, the device can also include a temperature sensor. To reduce intrusion into the internal components of the material measuring device, the temperature sensor can be integrated with a pressure sensor, with both temperature and pressure sensors installed inside the device.

[0150] For example, based on temperature and pressure data obtained from multiple locations by the temperature and pressure sensors, the mass ratio and density ratio of each substance in the test substance can be calculated using the PVT algorithm.

[0151] Using the substance to be tested as a three-phase mixture of oil, gas and water, the mass ratio of gas and oil in the three-phase mixture can be calculated based on temperature and pressure data from multiple locations, combined with the PVT algorithm, and the density ratio of each phase in the three-phase mixture of oil, gas and water can be calculated based on the density calculation formula.

[0152] Furthermore, by combining the gas-oil mass ratio, the density ratio of each phase, the artificial high gas flow rate, and the calculations of the artificial high model, the flow rate of each phase in the analyte can be determined.

[0153] For example, the cross-sectional water content of the analyte can be detected using a resonant cavity sensor and a microwave detector. The initial artificial high gas flow rate of the analyte is determined based on the pressure difference data generated within the material measuring device. Then, the flow rates of each phase of the analyte are determined by combining the gas-oil mass ratio, the density ratio of each phase, the cross-sectional water content, and the initial artificial high gas flow rate.

[0154] Alternatively, a virtual height model can be used to calculate the flow rate of each phase.

[0155] For example, the Froude number of the gas phase can be calculated based on the real-time virtual high gas flow rate, followed by the volumetric liquid content, then the Loma parameters, and finally the virtual high gas flow rate updated by substituting these parameters into the ultra-virtual high model. This process is repeated until the determined virtual high gas flow rate converges, at which point the gas flow rate calculation process ends. After the gas flow rate is determined, the flow rates of other phases in the analyte are then calculated.

[0156] For example, to facilitate the identification of the flow pattern of the substance under test, a wire mesh sensor (WMS) can be used to acquire cross-sectional image data of the flow section of the substance. Exemplarily, the wire mesh sensor can be installed at one of the locations within the channels of the first pipe 210 or the second pipe 220 of the substance measuring device.

[0157] For example, the wire mesh sensor can be a resistive wire mesh sensor. The wire mesh imaging results obtained by the wire mesh sensor can reflect information about the spatiotemporal distribution of gas and liquid within the pipe. In one example, the wire mesh sensor can be arranged in a 16*16 orthogonal configuration, achieving a maximum resolution of 3.125 mm in a 50 mm pipe diameter. The wire mesh sensor system can achieve an imaging rate of 250 frames per second. Of course, in other examples, with different wire mesh sensor layouts, it can be applied to other pipe diameters, potentially achieving different resolutions and imaging rates.

[0158] Taking a 16*16 orthogonal layout wire mesh sensor as an example, this sensor uses a cyclic scanning excitation method during operation. The 16 excitation electrodes share the same signal source, requiring a suitable electronic analog switch. For example, the typical on-resistance can be 4Ω, allowing bipolar signals of ±5V-±15V to pass through. The maximum continuous current allowed per channel is 115 mA, and the typical switching time is 140 ns. To prevent mutual interference between different excitation electrodes, all other excitation electrodes are forcibly grounded during the excitation cycle of one electrode. In a physical context, the change in local liquid content at the intersection of the excitation and receiving electrodes reflects the resistance. Under constant voltage source excitation, the change in resistance manifests as a change in current. Since directly measuring the magnitude of the current signal is difficult, in circuit design, the changing current signal is usually converted into a voltage signal, but the converted voltage signal is still a square wave.

[0159] Optionally, the substance measuring device can also be used to measure the content of various substances in some solid analytes, which can be placed directly in the channels of the substance measuring device. To achieve accurate measurement, the substance measuring device needs to be in a sealed state. To better meet the measurement requirements of solid analytes, the substance measuring device can also be equipped with sealing caps that seal the openings of the first and second channels.

[0160] In the material measuring device provided in the above embodiments, it can combine the signal generated by the flowing substance to be measured and various data during the flow to calculate the content, flow rate, and concentration of each substance. This method of measurement offers high sensitivity, requires no reagents or sampling, and has good environmental adaptability.

[0161] This application also provides an oilfield measurement device, which may include: a microwave resonant sensor, a first pipe 210, a second pipe 220, and a fluid dynamics sensor 230.

[0162] The microwave resonant sensor may include a through channel for measuring the resonant signal of an oil-containing fluid.

[0163] For example, the structure of this microwave resonant sensor can be similar to... Figure 1a and Figure 1b The resonant cavity sensor shown has a similar structure. It has a microwave resonant cavity 110, a receiving cavity 130, and a microwave detector 120. The microwave detector 120 can emit and receive microwave signals to obtain a resonant signal; the resonant signal is used to detect the water content in the oil in the oil field.

[0164] For further details regarding the microwave resonant sensor in the embodiments of this application, please refer to the description of the resonant cavity sensor in the foregoing embodiments, which will not be repeated here.

[0165] A first conduit 210 is disposed at the first end of the channel of the microwave resonant sensor, and a second conduit 220 is disposed at the second end of the channel of the microwave resonant sensor. The first conduit 210 and the second conduit 220 are used to connect to the pipeline of the oil field to be tested, and the first conduit 210, the second conduit 220, and the channel of the microwave resonant sensor are interconnected. The receiving cavity 130 of the microwave resonant sensor is disposed within the channel, and the first conduit 210 and the second conduit 220 are connected to the receiving cavity 130 of the microwave resonant sensor.

[0166] The fluid dynamics sensor 230 is disposed in the space where the first pipe 210, the second pipe 220 and the microwave resonant sensor channel are connected, and is used to measure the fluid dynamics parameters.

[0167] Among them, the resonant signal and fluid dynamic parameters are used to calculate the three-phase flow rates of oil, gas and water in the oil field.

[0168] Optionally, the first pipe 210 and the second pipe 220 can form a Venturi structure, and the microwave resonant sensor can be installed in the throat of the Venturi structure.

[0169] Optionally, the first conduit 210 can be a venturi structure, and the microwave resonant sensor can be mounted at the tail of the venturi structure.

[0170] Optionally, the second conduit 220 can be a venturi structure, and the microwave resonant sensor can be installed at the beginning of the venturi structure.

[0171] In this embodiment, the fluid dynamics sensor 230 includes a differential pressure sensor for measuring the pressure difference between at least two designated locations in the channel formed by the first pipe 210, the second pipe 220, and the channel of the microwave resonant sensor.

[0172] Optionally, the fluid dynamics sensor 230 includes a velocity sensor for measuring velocity parameters in the mixture of the oilfield under test in the channel formed by the first pipe 210, the second pipe 220, and the channel of the microwave resonant sensor.

[0173] Optionally, the fluid dynamics sensor 230 includes a temperature and pressure sensor for measuring temperature and pressure parameters in the channel formed by the first pipe 210, the second pipe 220, and the channel of the microwave resonant sensor.

[0174] The possible structure and installation position of the fluid dynamics sensor 230 may be similar to those of the fluid dynamics sensor 230 in the aforementioned material measuring device. For details, please refer to the description in the aforementioned material measuring device embodiment, which will not be repeated here.

[0175] In this embodiment, the oilfield measuring device may further include a wire mesh sensor.

[0176] The wire mesh sensor can be set in the channel formed by the first pipe 210, the second pipe 220 and the channel of the microwave resonant sensor, and is used to acquire the distribution image of the mixture in the oil field to be tested within the channel.

[0177] The wire mesh sensor in this embodiment can be similar to the wire mesh sensor provided in the aforementioned material measuring device. Other details about the wire mesh sensor can be found in the description of the material measuring device in the aforementioned embodiment, and will not be repeated here.

[0178] To better meet the measurement needs of oil fields or oil and gas fields, this oil field measurement device can also be equipped with more sensors based on on-site requirements.

[0179] Optionally, the oilfield measurement device may also include a locator to facilitate the location of the oil and gas fields measured by the device. In a scenario where multiple oilfields need to be measured and managed, the oilfield measurement device may also include a locator. By locating each oilfield measurement device using the locator, the situation of each oilfield can be better understood based on the location information combined with the measurement data obtained from each device.

[0180] Optionally, the oilfield measuring device may also include a display for showing real-time measured data related to the oilfield.

[0181] Optionally, the oilfield measuring device may further include an input / output unit. For example, the input / output unit may be a physical button, through which the required operation is performed. For example, the input / output unit may be implemented through the aforementioned display, which may be a touch screen display, where the required operation is achieved by operating the screen.

[0182] In one example, the oilfield measurement device can be configured with a variety of optional calculation models, and the calculation model can be selected from the variety of optional calculation models through the input / output unit.

[0183] In one instance, this input / output unit allows users to select data from existing records obtained by an oilfield measuring device.

[0184] The aforementioned oilfield measurement device enables measurements to be performed on specific oilfield or oil and gas field scenarios. Specifically, the device combines resonant signals with fluid dynamic parameters generated within the device to achieve measurements, eliminating the need for chemical analysis of the oilfield or oil and gas field. This reduces the difficulty of measurement and improves the measurement results.

[0185] To better adapt to the measurement of substance content in more application scenarios, the required substance measuring device can be adaptively adjusted based on actual needs. This application provides a method for determining a substance measuring device, which can be used to determine the substance measuring device provided in the foregoing embodiments. Figure 8 As shown, the method for determining the substance measurement device may include the following steps.

[0186] Step 310: Determine the type of substance measuring device based on the substance to be tested and the estimated content of each substance in the substance to be tested.

[0187] For example, this method for determining a substance measuring device can be applied to a terminal device with a display. The display of the terminal device can show the user interface of an application that implements the method for determining a substance measuring device.

[0188] The analyte and its estimated content can be information received from the user interface. For example, the user interface can receive manually input information, which may include the analyte and its estimated content. For example, the user interface can receive information selected from multiple preset test options, each of which may include the analyte and its estimated content.

[0189] Optionally, the substance to be tested may be included in the information received by the operation interface. For example, the information received by the operation interface may include the substance to be tested and its associated information. This associated information may include the region where the substance to be tested is located, its classification level, etc. The estimated content of each component of the substance to be tested can be determined based on the input associated information. Taking a gas field as an example, if the area where the gas field is located is a high-gas-content area, the estimated content of each component of the substance to be tested in that area could be high gas content and low water content. Taking an oil field as an example, the estimated content of each component of the substance to be tested in that area could be low oil content and high water content.

[0190] The substance to be tested can be classified into liquid, gas, solid, and other states. Different types of substance measuring devices can be selected for different states of the substance to be tested. For example, different types of substance measuring devices require different detection states. For instance, for detecting liquids in a large area, the substance measuring device can be a device that can be connected to the transmission pipeline in the large area. As another example, for detecting solid objects, the substance measuring device can be a device that can be independently sealed.

[0191] The substances to be tested can also be categorized as highly corrosive, highly viscous, low corrosive, and low viscous. Different types of measuring devices can be selected for different categories of substances. For example, when measuring highly corrosive substances, the internal material of the measuring device can be a corrosion-resistant material. Similarly, when measuring highly viscous substances, the internal material of the measuring device can be a material that does not readily absorb substances.

[0192] Optionally, more types of measuring devices can be classified based on additional characteristics of the analyte. Different types of measuring devices can better meet the measurement needs of analytes with different properties.

[0193] Step 320: Based on the requirements of the type of material measuring device, determine the first pipe and the second pipe of the material measuring device.

[0194] For different types of material measuring devices, the first pipe 210 and the second pipe 220 can be the same or different.

[0195] The first pipe 210 can be a pipe of equal diameter or a flared pipe. The second pipe 220 can also be a pipe of equal diameter or a flared pipe.

[0196] Step 330: A material measuring device is formed based on the first pipe 210 and the second pipe 220.

[0197] The material measuring device determined based on the above steps can be used to measure the material to be measured.

[0198] For example, after the terminal device forms a material measuring device, it can present complete information about the material measuring device in formats such as images or files. This complete information may include a schematic diagram of the material measuring device and its parameters. These parameters may include the model, size, material, shape, and other parameters of each component of the material measuring device.

[0199] In this embodiment, the material measuring device can be assembled based on the complete information of the material measuring device.

[0200] In one application scenario, this method for determining a substance measuring device is used in a terminal device equipped with a display. This terminal device can run an application that sells the substance measuring device. The application's sales interface can be displayed on the screen. A sales order can be generated when the substance measuring device is assembled, and subsequent sales operations can proceed based on this sales order. For example, orders awaiting shipment, logistics orders, etc., can be determined based on this sales order.

[0201] Based on the above implementation methods, material measuring devices can be customized according to actual measurement needs, thereby better meeting the measurement needs in more scenarios.

[0202] In one embodiment, the type of material measuring device includes: a two-phase material measuring device. A two-phase material can be two different compounds, or it can be a substance comprising two different phases.

[0203] Step 310 above may include: when the substance to be measured contains two substances, determining that the type of substance measuring device is a two-phase substance measuring device.

[0204] Since the measurement of a mixture containing only two compounds is relatively simple, the most basic structure can be used. For example, the substance measuring device may consist only of a first conduit 210, a second conduit 220, and a resonant cavity sensor.

[0205] The shapes of the first pipe 210 and the second pipe 220 are also unrestricted. They can be flared pipes or pipes of equal diameter.

[0206] Step 320 above may include: determining the first pipe 210 and the second pipe 220 of the material measuring device based on the requirements for measuring two-phase substances.

[0207] The determination of the first pipe 210 and the second pipe 220 of the material measuring device may include: determining the first pipe 210 and the second pipe 220 from a variety of pipe combinations that can be preset; or determining the first pipe 210 and the second pipe 220 based on the selection received from the user.

[0208] In one embodiment, the type of material measuring device includes those for measuring multiphase substances. Exemplarily, the multiphase substance may include substances in liquid, gas, or other states. Liquid substances may also include one or more compounds.

[0209] Step 310 above may include: when the substance to be measured contains at least three substances, determining that the type of substance measuring device is a multiphase substance measuring device.

[0210] The device for measuring multiphase substances includes a hydrodynamic sensor 230. When the information of the multiphase substance to be measured is complex, such as when it is necessary to measure the flow rate of each phase in the multiphase substance, a first pipe 210 and a second pipe 220 that can form a pressure difference can be selected.

[0211] Step 320 above may include: determining the first pipe 210 and the second pipe 220 of the material measuring device based on the requirements for measuring multiphase materials.
