Description

Technical Field

[0001] The present disclosure relates to the field of oil field technology, and in particular to a single-phase flow measurement method and device, electronic equipment, storage medium and instrument. Background Art

[0002] With the rapid development and progress of science and technology, the demand for oil in all walks of life has continued to rise, and my country's annual imports of oil resources and domestic production have repeatedly set new records. Low-permeability oil fields in my country are widely distributed. Their structures are complex, their permeability is low, and their development is difficult, so that the single-well production is generally low. Horizontal logging technology is a very important technology in oil and gas exploration and development. It is suitable for the exploitation of low-permeability, low-pressure, heavy oil wells and other types of oil reservoirs with complex ground conditions and difficult to effectively mobilize. By drilling horizontal and highly deviated wells, the wellbore trajectory can pass through more oil reservoirs, which can greatly improve the production capacity of oil and gas wells, maximize the potential of each reservoir, and increase the oil leakage area. At the same time, it can improve the potential for tapping remaining oil, increase the single-well production and crude oil recovery rate of low-permeability oil fields, and reduce production costs. It has a higher production capacity than vertical wells, and its production is generally 3 to 5 times that of vertical wells. However, affected by the water drive recovery technology, horizontal wells are prone to flooding in the later stages of development. Once the horizontal well is flooded, the production will drop sharply or even be scrapped. Horizontal well production testing technology is an important means to detect problematic horizontal wells. It can accurately indicate the production status of water-producing layers and each production layer, and then provide technical support for the next step of water plugging, fracturing, etc. However, the current difficulty in testing the production profile of horizontal wells is relatively large, mainly reflected in:

[0003] 1. The impact of large-scale fracturing technology on testing. Fracturing technology mainly refers to the use of water to create cracks above the oil field. It has now become an effective means to increase oil field production and efficiency. The objects of fracturing transformation are expanding towards very dense oil and gas reservoirs. Multi-stage and multi-cluster horizontal wells are the development direction of fracturing technology. The application of this fracturing technology makes the horizontal wells also present a multi-stage and multi-cluster liquid production state after fracturing. However, due to the generally low single-well production capacity of horizontal wells in low-permeability reservoirs, taking Daqing Oilfield as an example, the production of a single horizontal well is about 20. Therefore, under the conditions of multi-stage and multi-cluster fracturing, the single-stage production may be lower than 0.1. Therefore, in the case of low liquid production, there is no corresponding flow test technology to meet the flow range and flow lower limit, which seriously affects the accurate measurement of the output profile.

[0004] 2. Limitations of the application of existing technologies in horizontal well testing. Our current horizontal well testing technology mainly uses a combination of flowmeter and water content meter for dynamic measurement, but there are two main problems. First, the measurement lower limit of the current flow sensor cannot meet the requirements of multi-segment and multi-cluster fine measurement; the instruments for measuring the flow of horizontal well output profiles that are widely used are mainly turbine flowmeter, ultrasonic flowmeter, tracer flowmeter, electromagnetic flowmeter, thermal pulse flowmeter, etc. However, the traditional turbine flowmeter is easily affected by sand card, and its flow measurement lower limit is 1; the ultrasonic flowmeter is easily affected by the complex fluid structure distribution and ambient temperature, and its flow measurement lower limit is 5; the tracer method is simple in principle, but the tracer will cause contamination to the fluid and endanger the safety of personnel; the electromagnetic flow measurement method is widely used in the field of flow measurement with high water content or water as the continuous phase, but it is limited to pipe flow with axisymmetric distribution of fluid velocity. Second, the current logging method has a large error. Under low fluid production conditions, the lower limit of the flow cannot be reached, and the measurement error of the water content under this condition is also large, resulting in the error of the interpreted oil phase flow being further amplified. Therefore, it is urgent to develop a new testing technology that can accurately test the oil and water flow rates of low-liquid production horizontal wells. Summary of the invention

[0102] Figure 4 FIG. 1 is a schematic diagram showing the structure of the first cavity and the second cavity in the single-phase flow measurement instrument according to an embodiment of the present disclosure. Figure 4As shown, the inner side of one end of the first cavity has a sealing surface 19, and the other end of the first cavity has the liquid inlet; the outer side of one end of the second cavity has a cavity sealing ring 20, and the other end of the second cavity has the liquid outlet; the cavity sealing ring 20 is connected with the sealing surface 19 to seal the first cavity and the second cavity. The flow guide mechanism is installed on the axial cross section of the inner side of the first cavity or the second cavity, and the lower end of the flow guide mechanism has a flow channel with a set distance from the inner side of the first cavity or the second cavity.

[0103] In the embodiment of the present disclosure and other possible embodiments, the flow guide mechanism is a phase control plate 18. The phase control of the fluid (oil and water) in the cavity is achieved through the combination of the first phase control rotating cavity 6 (first cavity) and the second phase control rotating cavity 21 (second cavity). Figure 4 As shown in (a), the first phase state regulating rotating chamber 6 comprises: a liquid inlet 7 of the first phase state regulating rotating chamber, a sealing ring 8, a phase state regulating plate 18, a first sealing surface 19 and an array conductivity sensor 9. Figure 4 As shown in (b), the second phase regulating rotating cavity 21 includes: a liquid outlet 10 of the second phase regulating rotating cavity, a second sealing surface 27 and a cavity sealing ring 20.

[0104] In the embodiment of the present disclosure and other possible embodiments, the liquid inlet 7 of the first phase state regulating rotating cavity and the liquid outlet 10 of the second phase state regulating rotating cavity are located on opposite sides of the bottom end of the phase state regulating plate 18, and the line connecting the center point of the liquid inlet 7 of the first phase state regulating rotating cavity and the center point of the liquid outlet 10 of the second phase state regulating rotating cavity is parallel to the axis of the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21. The liquid inlet 7 of the first phase state regulating rotating cavity and the liquid outlet 10 of the second phase state regulating rotating cavity are square holes opened in the side wall of the cavity, and the two square holes are the only entrances and exits for the fluid to enter and flow out of the cavity. The first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21 realize the sealing connection between the cavities through the first sealing surface 19 and the second sealing surface 27. The shell wall thickness of the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21 is consistent. The first sealing surface 19 and the second sealing surface 27 of the two are reduced in diameter, so that the inner diameter of the first sealing surface 19 and the outer diameter of the second sealing surface 27 are only 1 mm apart. During installation, the second sealing surface 27 of the second phase state regulating rotating cavity 21 can be inserted into the first sealing surface 19 of the first phase state regulating rotating cavity 6. During the insertion process, the second sealing surface 27 will stop at the reduced diameter point between the shell of the first phase state regulating rotating cavity 6 and the first sealing surface 19, so that the two sealing surfaces are completely aligned in the axial direction.

[0105] In the embodiment of the present disclosure, there is a sealing mechanism between the first cavity and the outer side of the first cavity and the inner side of the sleeve 3; the sealing mechanism is used to isolate the area of ​​the liquid inlet and the liquid outlet. For example, the sealing mechanism is a sealing ring 8. In the embodiment of the present disclosure and other possible embodiments, two grooves are formed on the second sealing surface 27, and a cavity sealing ring 20 is installed in the groove. The function of the cavity sealing ring 20 is to seal the connection between the sealing surfaces of the first phase-state regulating rotating cavity 6 and the second phase-state regulating rotating cavity 21. This structural design can not only ensure that the fluid inside the cavity will not flow out from the connection, but also will not affect the radial rotation of the first phase-state regulating rotating cavity 6 and the second phase-state regulating rotating cavity 21. The function of the sealing ring 8 is to seal the annular space between the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21 and the outer shell 5, so that the fluid in the collecting channel must flow through the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21, and then flow out after being regulated by the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21.

[0106] In the embodiment of the present disclosure and other possible embodiments, the flow guide mechanism is installed on the axial cross section of the inner side of the first cavity or the second cavity, and the lower end of the flow guide mechanism has a flow channel with a set distance from the inner side of the first cavity or the second cavity. Those skilled in the art can set the flow channel with the set distance according to actual needs, for example, it can be set to 30 mm.

[0107] Figure 5 FIG. 1 is a schematic diagram showing the installation of an array conductivity sensor in a single-phase flow measurement instrument according to an embodiment of the present disclosure. Figure 5As shown, the flow guide mechanism is a phase regulating plate 18, which is installed on the axial cross section of the first phase regulating rotating cavity 6, at a set position (1930mm) away from the first sealing surface. The outer edge of the phase regulating plate 18 is sealed and connected to the inner wall of the first phase regulating rotating cavity 6 by welding. The phase regulating plate 18 occupies 4 / 5 of the cross-sectional area of ​​the cavity, leaving only a small circular notch 3-4 with a cross-sectional area of ​​1 / 5, which is used to regulate the fluid in the first phase regulating rotating cavity 6 and the second phase regulating rotating cavity 21. The chord 3-2 of the small circular notch 3-4 is perpendicular to the line formed by the center points of the liquid inlet 7 of the first phase regulating rotating cavity and the liquid outlet 10 of the second phase regulating rotating cavity, and the perpendicular bisector of the chord of the small circular notch 3-4 passes through the midpoint of the line connecting the liquid inlet 7 of the first phase regulating rotating cavity and the liquid outlet 10 of the second phase regulating rotating cavity. The center point of the string 3-2 is close to the center point connecting line of the liquid inlet 7 of the first phase state regulating rotating cavity and the liquid outlet 10 of the second phase state regulating rotating cavity. The phase state regulating plate 18 is used to control the flow state of the fluid entering the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21, and can assist in constructing the environment of the accumulation of oil and water single-phase fluid in the fluid inside the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21. The array conductivity sensor 9 is used to record the accumulation process of oil and water single-phase fluid in the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21 under the phase state regulating state, and then the oil and water single-phase volume flow rate can be derived. The array conductivity sensor 9 is composed of 8 conductivity probe arrays 3-1 distributed at equal intervals on the center line of the phase state regulating plate 18 perpendicular to the base of the phase state regulating baffle 18, and the diameter of the 8 conductivity probe arrays 3-1 is perpendicular to the center line of the liquid inlet 7 and the liquid outlet 10.

[0108] The working principle of the dual-rotation three-mode oil-water phase state regulation single-phase flow measurement combination instrument is: first, use a tractor to transport the dual-rotation three-mode oil-water phase state regulation single-phase flow measurement combination instrument to the horizontal well to be tested, then restore the normal production state of the oil well, and after the production is stable, the collector of the combination instrument is short-circuited and opened through the ground power supply and command control, forcing the fluid to enter the current collection measurement channel. Then, enter the flow test phase, which is divided into three main steps: Step 1, initialization of the fluid in the cavity under mode 1 (initialize the first cavity and the second cavity connected to the first cavity, so that the first cavity and the second cavity are in the water phase state); Step 2, oil phase single-phase flow measurement under mode 2 (the first cavity is in the oil phase state and the second cavity is in the water phase state); Step 3, water phase single-phase flow measurement under mode 3 (the first cavity is in the water phase state and the second cavity is in the oil phase state).

[0109] Step 1: Initializing the fluid in the cavity of the mode 1 (initializing the first cavity and the second cavity connected to the first cavity, so that the first cavity and the second cavity are in the water phase state).

[0110] Figure 6 FIG. 1 is a schematic diagram of a state-one initialization cavity (the first cavity and the second cavity are in the water phase) according to an embodiment of the present disclosure. The gray color represents the oil phase liquid surface, and the white color represents the water phase liquid surface. Figure 6 (a) shows the early stage of phase initialization. The ground sends a first preset position command to drive the first rotary drive motor 25 and the second rotary drive motor 14 to rotate respectively, and the ground monitors the output values ​​of the first orientation sensor 24 and the second rotary drive motor 13 at the same time. When the output value shows that the liquid inlet 7 and the liquid outlet 10 are adjusted to the top (first side) of the first phase state regulation rotating cavity 6 and the second phase state regulation rotating cavity 21, the rotation of the first phase state regulation drive motor 25 and the second rotary drive motor 14 is stopped, and the instrument enters the phase state initialization mode.

[0111] Under the condition of oil-water stratified flow in a low-liquid production horizontal well, the oil-water mixed phase fluid flowing in the casing 3 is collected by the collector 4, first enters the well logging instrument from the instrument liquid inlet 2, and then enters the cavity from the liquid inlet 7. Affected by the different gravity of oil and water, oil and water separation will occur after the oil-water mixed phase enters the instrument. Since the liquid inlet 7 and the liquid outlet 10 are at the top of the instrument in the phase initialization state, at this time, the oil phase will continue to enter the cavity from the liquid inlet 7, and drift and flow above the cavity to the liquid outlet 10 to flow out. In this phase control state, the oil phase is easy to be released. After the fluid flow state is stable, the cavity is almost full of water. Figure 4 -b, the phase initialization late stable stage; then, the liquid inlet 7 and the liquid outlet 10 are closed to complete the initialization (the first cavity and the second cavity are in the water phase).

[0112] Step 2: single-phase flow measurement of oil phase under mode 2 (the first cavity is in the oil phase and the second cavity is in the water phase).

[0113] Fig. 9 A schematic diagram of a two-phase oil-phase single-phase flow measurement cavity according to the state (the first cavity is in the oil phase state and the second cavity is in the water phase state) is shown. Fig. 9 (a) is the early stage of oil phase single-phase flow measurement; Fig. 9 (b) is the middle stage of oil phase single-phase flow measurement; Fig. 9 (c) is the late stable stage of oil phase single-phase flow measurement; Fig. 9 (a)- Fig. 9 (b) Volume and flow records of the oil phase; gray is the oil phase liquid surface, and white is the water phase liquid surface.

[0114] like Fig. 9 As shown in (a), the ground sends a second preset position instruction to drive the first rotary drive motor 25 and the second rotary drive motor 14 to rotate respectively. At the same time, the ground monitors the output values ​​of the first position sensor 24 and the second position sensor 13. When the output values ​​show that the liquid inlet 7 and the liquid outlet 10 are adjusted to the top and bottom of the first phase-regulating rotary cavity 6 and the second phase-regulating rotary cavity 21 (the second side opposite to the first side), the rotation of the first rotary drive motor 25 and the second rotary drive motor 14 is stopped, and the instrument enters the phase initialization state. At this time, the instrument enters the oil phase single-phase flow measurement mode. This measurement is performed on the basis of phase initialization, that is, under the premise that the cavity is almost full of water (the first cavity is in the oil phase and the second cavity is in the water phase).

[0115] Under the condition of oil-water stratified flow in a low-liquid production horizontal well, the oil-water mixed phase fluid flowing in the casing 3 is collected by the collector 4, first enters the well logging instrument from the well logging instrument liquid inlet 2, and then enters the cavity from the liquid inlet 7. At this time, the oil-water mixed phase fluid is affected by gravity, and oil-water separation occurs after entering the instrument, that is, the upper layer is the oil phase, and the lower layer is the water phase. Since the liquid inlet 7 and the liquid outlet 10 are at the bottom of the instrument in the oil phase single-phase flow measurement state, at this time, the water phase will continue to enter the cavity from the liquid inlet 7, and flow out to the liquid outlet 10, while the oil phase accumulates outside the cavity. As time goes by, the oil phase will gradually accumulate at the liquid inlet 7 at the bottom of the cavity, and enter the cavity from the liquid inlet 7. After entering the cavity, the oil phase will first drift upward under the influence of the buoyancy of the water phase, and gradually accumulate on the left side of the phase state regulating baffle 18 in the cavity. After accumulating to the lower edge of the phase state regulating baffle 18, it will flow to the space on the right side of the phase state regulating baffle 18 and continue to accumulate, as shown in FIG. Fig. 9 As shown in (b), after the oil phase accumulates on both sides of the phase control baffle 18, it continues to accumulate downwards and finally flows out from the liquid outlet 10 of the phase control rotating chamber. It is particularly important to note that the entire process of oil phase accumulation in this state is not affected by the flow of the water phase. In this control state, the accumulation process of the oil phase on the left side of the phase control plate 18 is fully recorded by the conductivity probe array 3-1 installed on the phase control plate 18. The working principle of the conductivity probe array 3-1 is to measure the resistivity of the liquid it contacts. When the probe is immersed in the water phase, the response value is low, and when it is immersed in the oil phase, the response value is high. As the oil phase enters the cavity, the oil phase begins to immerse the conductivity probe array 3-1. Every time the oil phase liquid surface immerses a conductivity probe array 3-1, the instrument response value rises by one step, such as Figure 8 As shown, the response value increases with the number of immersions and accumulates continuously, and finally reaches the highest value when all the oil phase is immersed. Therefore, the height of the oil phase liquid level in the cavity can be obtained in real time by using the 8 conductivity probe arrays 3-1.

[0116] After the conductivity probe measurement is completed, the oil phase will continue to accumulate according to the aforementioned flow law and eventually reach a stable state, such as Fig. 9 As shown in (c), at this time, the accumulated amount of oil phase in the cavity (the first cavity and the second cavity) is the largest, which is almost a full oil state. At this point, the single-phase flow measurement of the oil phase under mode 2 is completed.

[0117] Figure 7 A schematic diagram of the cumulative cross-section of the oil phase in the first phase regulation rotating cavity (first cavity) according to an embodiment of the present disclosure is shown. Figure 7 (a) is the case where the oil phase liquid surface is higher than the radius; Figure 7 (b) is the case where the oil phase liquid level is lower than the radius; wherein the gray is the oil phase liquid level, and the white is the water phase liquid level. It should be noted that the first cavity and the second cavity in the embodiment of the present disclosure are cylindrical, and in other possible embodiments, they may be square, conical or other shapes. Those skilled in the art may select or determine the shapes of the first cavity and the second cavity according to actual needs.

[0118] Under horizontal conditions, when the oil phase liquid level is higher than the radius, the cumulative volume of the oil phase in the cavity is calculated as formula (3); when the oil phase liquid level is lower than the radius, the cumulative volume of the oil phase in the cavity is calculated as formula (4):

[0119]

[0120]

[0121] Among them, h o is the height of the oil phase liquid level; d is the diameter of the phase state regulating rotating cavity; L is the length of the phase state regulating rotating cavity.

[0122] Figure 8 FIG. 2 is a schematic diagram showing the response law of the conductivity sensor of the oil phase flow measurement array according to an embodiment of the present disclosure. Figure 8 As shown in Figure 2, since the cavity volume V corresponding to the probe height is fixed, assuming that the flow rate and water content are fixed, the following can be obtained: Figure 8 Schematic diagram of the response law of the conductivity sensor of the oil phase flow measurement array is shown.

[0123] By recording the accumulated amount and accumulated time of the oil phase in the cavity, the oil phase flow rate or the oil phase change law can be calculated, so that the oil phase flow rate or the oil phase change law of the measured layer under the oil-water stratified flow condition of the low-liquid production horizontal well can be effectively obtained according to the calculation formula shown in the following formula (5):

[0124] Q o =ΔV o / Δt o (5);

[0125] In the formula, when Qo is the volume change law of the oil phase; ΔV o is the cavity volume between two adjacent probes; Δt o is the time taken by the oil phase to immerse two adjacent probes. o is the volume flow rate of the oil phase, ΔV o is the cumulative volume of the oil phase in the cavity measured by the conductivity probe array; Δt o is the cumulative time corresponding to the cumulative volume of the oil phase in the cavity.

[0126] Step 3: single-phase flow measurement of water phase under mode 3 (the first cavity is in a water phase state and the second cavity is in an oil phase state).

[0127] Fig.12 A schematic diagram of a three-phase single-phase flow measurement chamber (the first chamber is in the water phase state and the second chamber is in the oil phase state) is shown. Fig.12 As shown, Fig.12 (a) is the early stage of water phase single-phase flow measurement Fig.12 (b) is the late stable stage of the water phase single-phase flow measurement; the gray is the oil phase liquid surface, and the white is the water phase liquid surface.

[0128] like Fig.12 As shown in (a), the ground sends a third preset position instruction to drive the first rotary drive motor 25 and the second rotary drive motor 14 to rotate respectively. At the same time, the ground monitors the output values ​​of the first position sensor 24 and the second position sensor 13. When the output values ​​show that the liquid inlet 7 is adjusted to the top of the first phase-regulating rotary cavity 6 (the first side), and the liquid outlet 10 of the phase-regulating rotary cavity is adjusted to the bottom of the second phase-regulating rotary cavity 21 (the second side opposite to the first side), the first rotary drive motor 25 and the second rotary drive motor 14 are stopped. At this time, the instrument enters the water phase single-phase flow measurement mode. This measurement is performed on the basis of the oil phase single-phase flow measurement, that is, it is performed under the premise that the cavity is almost full of oil.

[0129] like Fig.12As shown in (b), when the oil-water miscible fluid flows into the cavity, due to the liquid outlet 10 being located at the lower right side of the second phase state regulating rotating cavity 21, the original oil phase in the cavity is not easy to flow out due to the influence of gravity, and is driven to flow out from the position of the liquid outlet 10 by the liquid flowing in from the phase inlet 7, and the newly flowing oil phase will merge with the original oil phase in the cavity and continue to flow according to the flow law of the above-mentioned oil phase. After the water phase enters the cavity, it will naturally fall and flow into the cavity on the left side of the phase state regulating plate 18 under the influence of gravity, and gradually accumulate from the bottom. When the water phase accumulates on the left side of the cavity (the first cavity) to the upper edge of the phase state regulating plate 18, it will flow down along the phase state regulating plate 18 to the bottom of the right side of the cavity (the second cavity) and flow out from the liquid outlet 10. It should be noted that the whole process of water phase accumulation in this state is not affected by the flow of the oil phase. In this control state, the accumulation process of the water phase on the left side of the phase control plate 18 is fully recorded by the conductivity probe array 3-1 installed on the phase control plate 18. Before the water phase single-phase flow measurement under mode three begins, the response value of the conductivity probe array 3-1 shows the highest value when it is completely immersed in the oil phase. As the water phase enters the left side of the phase control plate 18 of the cavity, the water phase begins to immerse the conductivity probe array 3-1. Each time the water phase liquid surface immerses a conductivity probe array 3-1, the instrument response value decreases by one step. The response value begins to decrease continuously with the increase in the number of immersions, and finally reaches the lowest value when it is completely immersed in the water phase, such as Fig.11 Therefore, the height of the water phase liquid level in the cavity can be obtained in real time by using the 8 conductivity probe arrays 3-1.

[0130] Fig.10 FIG. 2 shows a schematic diagram of the cumulative cross-section of the water phase in the first phase state regulation rotating chamber (first chamber) according to an embodiment of the present disclosure. Fig.10 As shown, Fig.10 (a) is the case where the water phase surface is lower than the radius; Fig.10 (b) is the case where the water phase surface is higher than the radius; the gray is the oil phase surface, and the white is the water phase surface.

[0131] Under horizontal conditions, when the water phase liquid surface is lower than the radius, the cumulative volume of the water phase in the cavity is calculated as formula (6); when the water phase liquid surface is higher than the radius, the cumulative volume of the water phase in the cavity is calculated as formula (7):

[0132]

[0133]

[0134] Among them, h w is the height of the water phase liquid level; d is the diameter of the phase state regulating rotating cavity; L is the length of the phase state regulating rotating cavity.

[0135] Fig.11FIG. 2 is a schematic diagram showing the response law of the conductivity sensor array for measuring water phase flow according to an embodiment of the present disclosure. Fig.11 As shown in Figure 2, since the cavity volume V corresponding to the probe height is fixed, assuming that the flow rate and water content are fixed, the following can be obtained: Fig.11 Schematic diagram of the response law of the conductivity sensor of the water phase flow measurement array shown.

[0136] Since the cavity volume corresponding to the probe height is fixed, the water phase flow rate can be derived by calculating the cumulative amount and cumulative time of the water phase in the cavity. Therefore, the water phase flow rate of the measured layer section under the oil-water stratified flow conditions of a low-liquid production horizontal well can be effectively obtained according to the calculation formula shown in the following formula (8).

[0137] Q w =ΔV w / Δt w (8);

[0138] In the formula, Q w is the volume change law of the water phase; ΔV w is the cavity volume between the two probes; Δt w is the time taken by the water phase to immerse two adjacent probes. o is the volume flow rate of the water phase, ΔV o is the cumulative volume of water phase in the cavity measured by the conductivity probe array; Δt o is the cumulative time corresponding to the cumulative volume of water phase in the cavity.

[0139] After the measurement of the single-phase flow of the water phase is completed, one measurement cycle of the logging instrument is completed.

[0140] After the test cycle of this layer section is completed, if the measurement result is not ideal, repeat the measurement according to the above steps 1, 2, and 3 until you are satisfied with the measurement result. Finally, after all layers have completed the single-phase flow test, pull up the cable and recover the combination instrument and tractor.

[0141] In summary, the embodiment of the present disclosure includes: a first phase state regulating rotating cavity 6, an array conductivity sensor 9, a phase state regulating plate 18, a liquid inlet 7, a sealing ring 8, a first sealing surface, a second sealing surface 19, 27, a cavity sealing ring 20, a second phase state regulating rotating cavity 21 and a liquid outlet 10. The dual-rotation three-mode oil-water phase state regulating single-phase flow measurement combination instrument realizes the conversion between working modes one, two and three by the combined rotation of the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21, and then combines the measurement of the array conductivity sensor 9 to realize the function of time-sharing measurement of oil and water single-phase flow. The control of the first phase state regulating rotating cavity 6 and the second phase state regulating rotating cavity 21 and the measurement of the array conductivity sensor 9 are realized by the first circuit system 23 and the second circuit system 11 in the first circuit tube short circuit 22 and the second circuit tube short circuit 12.

[0142] The measuring instrument further includes: a controller; before the first driving mechanism and the second driving mechanism are used to drive the first cavity and the second cavity to rotate, so that the first cavity and the second cavity are in the initialized water phase state, the controller obtains preset horizontal position information; the first azimuth sensor and the second azimuth sensor respectively detect the first position information and / or the second position information of the first cavity and the second cavity in real time; the controller, according to the first position information and / or the second position information and the set horizontal position information, levels the first cavity and the second cavity, so that the first cavity and the second cavity are in a horizontal state. For details, please refer to the description of the above-mentioned single-phase flow measurement method.

[0143] At the same time, the instrument is suitable for testing single-phase flow rate of oil-water phase state regulation in horizontal wells in various transportation modes such as tractor transportation, oil pipe transportation, and continuous oil pipe transportation. The specific implementation method of the current collector short circuit can refer to the umbrella current collector method CN201020611183.8.

[0144] The present invention has the advantages of low flow measurement limit, high test accuracy, basically no moving parts in the sensor group, and high reliability. It can effectively solve the problems that the flow limit of the current horizontal well output profile logging instrument cannot meet production needs, the instrument reliability is poor, and the test accuracy is low. It is suitable for various logging processes such as tractor transportation and oil pipe transportation, can realize accurate measurement of downhole flow, and has broad application development prospects.
