Description

Technical Field

[0001] This invention relates to the field of drilling fluid and gas logging technology, and is an automatic desanding drilling fluid quantitative collection and measurement and formation gas separation device. Background Technology

[0002] In oil exploration, logging measurements of drilling fluid parameters involve installing sensors in buffer tanks. Formation gas collection, on the other hand, relies on electrically operated degassing devices to separate formation gas. During operation, these sensors and devices are subjected to high-speed flow of drilling fluid containing large amounts of cuttings, similar to water cutting, which can easily puncture and damage the core components, rendering them inoperable. Buffer tanks often lack automatic sand removal capabilities, easily burying sensors and degassing devices, leading to data measurement and formation gas collection failures. Particularly problematic are complex drilling processes and circulation side effects, where low-flow circulation results in insufficient drilling fluid at the outlet, failing to reach the minimum operating capacity of sensors and degassing devices. This results in ineffective sensor measurements and ineffective formation gas collection, leading to data loss. Some wells even lack buffer tanks altogether, preventing proper installation of sensors and degassing devices. Furthermore, the drilling fluid level within the buffer tank is unstable due to variable flow rates and human factors, affecting the optimal operation of sensors and degassing devices and hindering quantitative collection and measurement.

Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0019] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1 , 3As shown in Figure 4, the automatic desanding drilling fluid quantitative acquisition and measurement and formation gas separation device includes a main body 25, a quantitative acquisition device, a quantitative detection device, a sand removal device, a formation gas separation device, and a control unit. The quantitative acquisition device includes an acquisition unit 2 and a drilling fluid deceleration chamber 1. The drilling fluid deceleration chamber 1 is located on the left side inside the main body 25. The upper part of the drilling fluid deceleration chamber 1 is square. The right side inside the square part of the upper part of the drilling fluid deceleration chamber 1 is provided with a first deceleration plate 23. The bottom of the drilling fluid deceleration chamber 1 is conical. The upper left side of the drilling fluid deceleration chamber 1 has a through hole that runs through both the inside and outside. A deceleration chamber inlet pipe 3 is fixedly connected to the side, and a fluid monitoring sensor 4 is installed on the deceleration chamber inlet pipe 3. A data acquisition unit 2 is installed on the lower left side of the main body 25, and the outlet of the data acquisition unit 2 is fixedly connected to the deceleration chamber inlet pipe 3. Both the data acquisition unit 2 and the fluid monitoring sensor 4 are connected to the control unit. The quantitative detection device includes a drilling fluid measurement chamber 5, a parameter monitoring module, and a second deceleration plate 24. The drilling fluid measurement chamber 5 is located in the center of the main body 25. The upper part of the drilling fluid measurement chamber 5 is square, and a parameter monitoring module is located on the upper side inside the drilling fluid measurement chamber 5. The bottom of the measuring chamber 5 is conical. A second deceleration plate 24 is provided between the upper square part and the bottom conical part of the drilling fluid measuring chamber 5. The lower outer part of the conical part of the drilling fluid measuring chamber 5 is fixedly connected to the bottom of the drilling fluid deceleration chamber 1. A sand removal device is provided at the bottom of the drilling fluid measuring chamber 5. The sand removal device and the parameter monitoring module are both connected to the control unit. The formation gas separation device includes a formation gas separation chamber 10, a formation gas separator, and a condensation and gas collection tower 9. The formation gas separation chamber 10 is located on the left side of the main body 25 on the left side of the drilling fluid measuring chamber 5. The upper part of the formation gas separation chamber 10 is square. The upper left side of the separation chamber 10 is provided with a connecting hole that connects to the upper right side of the drilling fluid measuring chamber 5. The upper side of the formation gas separation chamber 10 is provided with a formation gas separator. The top of the formation gas separation chamber 10 is provided with a condensation and gas collection tower 9, which has an inverted conical structure. The top of the condensation and gas collection tower 9 is provided with a formation gas outlet. The lower part of the formation gas separation chamber 10 is semi-conical. The bottom of the formation gas separation chamber 10 is provided with an automatic drilling fluid discharge port 13. The lower outer side of the cone-shaped formation gas separation chamber 10 is provided with a liquid level monitoring sensor 12, which is connected to the control unit.

[0020] The aforementioned control unit is a known technology and can be an STM32 series microcontroller. In use, the control unit is connected to an external host computer. The control unit controls the acquisition unit 2 to quantitatively collect drilling fluid. The collected drilling fluid enters the drilling fluid deceleration chamber 1 through the deceleration chamber inlet pipe 3. The high-speed flowing drilling fluid is firstly decelerated by the first deceleration plate 23 on the right side inside the drilling fluid deceleration chamber 1, and then secondly decelerated by the conical structure at the bottom of the drilling fluid deceleration chamber 1, allowing the drilling fluid to enter the drilling fluid measurement chamber 5 at a uniform speed. The second deceleration plate 24 inside the drilling fluid measurement chamber 5 performs a third-stage deceleration on the drilling fluid. The decelerated drilling fluid slowly enters the upper part of the drilling fluid measurement chamber 5 until it submerges the parameter monitoring module. The parameter monitoring module monitors parameters such as the temperature, density, and conductivity of the drilling fluid. The parameter monitoring module outputs the monitored drilling fluid parameters to the control unit, which then outputs them to the host computer. The drilling fluid enters the formation gas separation chamber 10 through the connecting hole. The formation gas separation chamber 10 separates the formation gas contained in the drilling fluid. After being condensed by the condensation and gas collection tower 9, the formation gas is output to other external equipment for analysis and processing through the formation gas output port. The drilling fluid in the formation gas separation chamber 10 is discharged into the formation gas separation chamber 10 through the drilling fluid automatic discharge port 13. At the same time, the liquid level monitoring sensor 12 installed on the lower side of the formation gas separation chamber 10 monitors the drilling fluid level in the formation gas separation chamber 10 and outputs it to the control unit. The control unit outputs it to the host computer, which facilitates the adjustment of the drilling fluid collection volume of the acquisition unit 2 based on the signal, and also facilitates later inspection. Meanwhile, the amount of drilling fluid entering the formation gas separation chamber 10 is based on the position of the liquid level monitoring sensor 12, and the drilling fluid is always kept covering the position of the drilling fluid automatic discharge port 13, isolating the drilling fluid automatic discharge port 13 from the upper gas separation part to prevent the formation gas output from the upper part from being diluted.

[0021] The first deceleration plate 23 is provided with multiple raised surfaces to facilitate deceleration of the drilling fluid after contact; the second deceleration plate 24 is provided with multiple through holes to achieve deceleration of the drilling fluid. In summary, this invention uses a quantitative acquisition device to quantitatively acquire drilling fluid parameters, a quantitative detection device to monitor drilling fluid parameters, and a formation gas separation device to separate formation gas from the drilling fluid. This effectively solves the problems caused by factors such as damage to the parameter monitoring module and degassing device due to high-speed flowing drilling fluid, sand accumulation, inability to install, small discharge rate, and unstable fluid level, which prevent the parameter monitoring module and degassing device from working properly or being damaged. It not only realizes the quantitative acquisition and monitoring of various drilling fluid parameters, but also effectively achieves the physical separation of formation gas, improving the authenticity, continuity, and quantification of logging parameters.

The outer side of the cone-shaped drilling fluid measuring chamber 5 is provided with an electromagnetic stirrer 16. Both the sand removal electric valve 14 and the electromagnetic stirrer 16 are connected to the control unit.

[0023] In the above embodiment, the drilling fluid filters large rock cuttings through the acquisition unit 2, but fine rock cuttings still enter. These fine rock cuttings will settle at the conical bottom of the drilling fluid measurement chamber 5. The control unit controls the electromagnetic stirrer 16 to stir the fine rock cuttings by rotating in real time to prevent sand from caking. The control unit controls the sand discharge electric valve 14 to open and automatically discharge the bottom sand through the automatic sand discharge outlet 15 to the bottom of the drilling fluid measurement chamber 5. By automatically discharging the sand, the parameter monitoring module is protected, and the accuracy and authenticity of the logging parameters are improved, providing a strong basis for ensuring the timely discovery of oil and gas reservoirs and rapid drilling. The opening time of the electromagnetic stirrer 16 and the sand discharge electric valve 14 is changed by the signal output from the fluid monitoring sensor 4 to the control unit, or the control unit fixes the opening time of the electromagnetic stirrer 16 and the sand discharge electric valve 14, and automatically starts the electromagnetic stirrer 16 and the sand discharge electric valve 14 after the fixed time is reached.

[0024] Example 3: Further optimizations to Example 1 above, as shown in the attached figure. Figure 2 As shown, a condensation device is provided inside the condensation collection tower 9. The condensation device includes an annular condensation layer 20, a planar condensation layer 21, and a microporous condensation layer 22. The annular condensation layer 20, the planar condensation layer 21, and the microporous condensation layer 22 are attached to the inside of the condensation collection tower 9 from the inside to the outside.

[0025] In the above embodiment, the drilling fluid entering the formation gas separation chamber 10 flows downward, while the gas undergoes three layers of condensation: annular condensation layer 20, planar condensation layer 21, and microporous condensation layer 22. A large amount of water is condensed and discharged to the formation gas separation chamber 10. The gas after the three-layer condensation treatment is supplied to other external equipment through the formation gas outlet for analysis and processing. By setting up the three-layer condensation treatment, the dryness of the gas is improved.

Figure 1 , 4 As shown, the parameter monitoring module includes a temperature sensor 6, a density sensor 8, and a conductivity sensor 7. The probes of the temperature sensor 6, density sensor 8, and conductivity sensor 7 are all arranged in a triangular array. The temperature sensor 6, density sensor 8, and conductivity sensor 7 are all connected to the control unit.

[0027] The temperature sensor 6, density sensor 8, and conductivity sensor 7 mentioned above are all existing known technologies, used to monitor the temperature, density, and conductivity parameters of the drilling fluid inside the drilling fluid measurement chamber 5, and output the monitored signals to the control unit; wherein the temperature sensor 6, density sensor 8, and conductivity sensor 7 are integrated, and the bottom of the probes of the temperature sensor 6, density sensor 8, and conductivity sensor 7 does not exceed the second deceleration plate 24, and the top of the probes of the temperature sensor 6, density sensor 8, and conductivity sensor 7 is 200mm away from the horizontal position of the connecting hole.

[0029] The aforementioned metering electric pump and metering electric valve are both existing known technologies. In use, either the metering electric pump or the metering electric valve can be selected for metered drilling fluid collection according to the actual situation. The metering electric pump is used when the external drilling fluid is in a buffer tank or transition tank. The inlet of the metering electric pump is fixedly installed in the buffer tank or transition tank for drilling fluid collection, and the control unit controls the metering electric pump to perform metered drilling fluid collection. The metering electric valve is used when the external pipeline is an elevated pipe and forms a certain slope with the outlet. The inlet of the metering electric valve is fixedly connected to the bottom of the elevated pipe, and the control unit controls the electric valve to achieve metered drilling fluid collection. The amount of drilling fluid collected by the metering electric pump or the metering electric valve is changed by the signal output by the liquid level monitoring sensor 12 located at the bottom of the formation gas separation chamber 10.

Figure 1 , 4 As shown, the formation gas separator includes multiple gas separation plates 11, which are arranged in a sloping trapezoidal pattern with higher sides and lower center, and the gas separation plates 11 on the left and right sides are staggered vertically.

[0031] When the above embodiments are used, several diamond-shaped holes or several protruding surfaces can be opened on the gas separation plate 11 to increase the irregular flow of drilling fluid. At the same time, by setting multiple gas separation plates 11 in a sloping trapezoidal distribution with high left and right sides and low middle, and the gas separation plates 11 on the left and right sides are staggered vertically, the flow area of ​​drilling fluid is increased, thereby achieving the function of separating formation gas.

[0032] Example 7: Further optimizations to Example 1 above, as shown in the attached figure.
