Description
Technical Field
[0001] This invention relates to the field of drilling inspection technology, and in particular to a novel intelligent drilling logging downhole equipment's drilling sample pool. Background Technology
[0002] With the continuous advancement of oil and gas development technologies and the ongoing optimization of oil and gas exploration techniques, drilling-while-drilling hydrocarbon detection technology has been injected as a fresh element into this optimized approach in recent years, securing an unshakeable position in the domestic and international oil and gas development industry. Equipped with a drilling-while-drilling system, a large number of detection tools are used to collect signal data from the bottom of the well, and this data is compared, analyzed, and processed to further determine relevant measures.
[0003] Currently, the hydrocarbon logging methods commonly used in oil and gas development are quite cumbersome. They involve transporting the oil and gas from the wellbore mud to the surface, separating the oil and gas, and then sending the separated oil and gas to an analyzer for testing. This approach has several drawbacks: First, it only allows surface testing, significantly increasing workload. Second, the extensive sample transport process fails to demonstrate the real-time nature of monitoring while drilling. Third, the lack of real-time monitoring while drilling can lead to misjudgments of the downhole environment, resulting in inaccurate identification of oil and gas formations and ultimately, inaccurate drilling depth. Many current technologies, whether formation hydrocarbon detection or logging hydrocarbon analysis, cannot achieve drill bit-following monitoring, let alone real-time sample extraction. Errors in data extraction lead to inaccurate data and, seriously, misjudgments of the actual downhole conditions. Summary of the Invention

[0013] This invention relates to a novel and ingenious sample pool for drilling monitoring in oil and gas development—a novel intelligent downhole sampling pool for logging-while-drilling equipment. This invention solves the problem of difficult extraction of oil-bearing drilling fluid from the upflow well.

In this embodiment, the detection lens 122 is the detection lens 122 of a laser Raman detector.
[0031] Power output port 155 supplies power to the cam disc electromagnetic device 102, speed sensor 111, impeller disc power controller 115, cam disc signal processor 103, temperature sensor 121, one-way valve signal processor 120, reversing valve signal processor 106, flow sensor 110, level monitor 132, and central processing unit 151. The central processing unit 151 is externally connected to a signal monitor, a computer, and a signal alarm.
[0032] A novel intelligent downhole logging equipment's sample pool undergoes the following process in a single use:
[0033] This device is installed downhole, with 109g of oil-bearing drilling fluid flowing upwards between the device and the wellbore.
[0034] (1) The downstream oil-bearing drilling fluid flows through the inlet of the signal-controlled electromagnetic reversing valve 107. Part of the liquid flows to the inlet of the sample cell, and part of the liquid is diverted through the signal-controlled electromagnetic reversing valve 107 to the bypass channel.
[0035] (2) The liquid flowing to the sample cell inlet flows into the upper impeller cavity, pushing the upper blade 112 on the outside of the upper impeller 113. The upper blade 112 drives the upper impeller 113 to rotate around the drive shaft 261. The upper impeller 113 and the cam drive wheel 104 are connected by the connecting sleeve 105. The upper impeller 113 and the cam drive wheel 104 rotate on the same axis and at the same angular velocity. While rotating around the drive shaft 261, the cam drive wheel 104 drives the drive shaft 261 to move left and right under the action of the slipper 255. The drive shaft 261 moves left and right in the spline groove 263, and at the same time drives the piston 118 to move left and right.
[0036] (3) When the piston 118 moves to the left, it generates suction, which draws the upward oil-bearing drilling fluid 109 into the piston chamber through the filter screen 124. At this time, the signal control electromagnetic check valve 123 is closed. Therefore, under the suction of the piston 118, the upward oil-bearing drilling fluid 109 is sent into the detection lens 122. When the piston 118 moves to the right, it generates thrust, which sends the upward oil-bearing drilling fluid 109 in the piston 118 chamber out of the piston 118 chamber. At the same time, the sample liquid under the detection lens 122 is sent into the well wall 140 through the check valve and then through the piston 118 chamber.
[0037] (4) The upward-flowing oil-bearing drilling fluid 109 from the upper impeller cavity flows into the lower impeller cavity through the intermediate channel. The downward-flowing oil-bearing drilling fluid pushes the lower blade 135, which in turn drives the lower impeller 130. The lower impeller 130 rotates around the fixed shaft 129 under the action of the bearing. After pushing the lower blade 135, the downward-flowing oil-bearing drilling fluid flows towards the sample pool outlet.
[0038] (5) The lower impeller 130 and the large gear 212 on the right are connected by a sleeve. Therefore, the impeller and the large gear 212 rotate coaxially and at the same speed. Since the large gear 212 meshes with the upper small gear 213, the large gear 212 drives the small gear 213 to rotate, completing the first-stage speed increase. Also, since the small gear 213 and the worm gear 214 are coaxial, the small gear 213 and the worm gear 214 rotate coaxially and at the same angular velocity. Also, since the worm gear 214 drives the worm 215 to rotate, completing the second-stage speed increase.
[0039] (6) After the speed-up of the gear worm gear 214, the generator rotor rotates at high speed. The high-strength magnets at both ends generate alternating current in the stator coil group. At the same time, the alternating current is converted into direct current after being rectified by electronic short-circuiting and then used to power the entire system through the power output port 155.
[0040] (7) The electricity generated by the generator is delivered through the power output port 155 to the electromagnetic device, speed sensor 111, impeller power controller, cam disk signal processor 103, temperature sensor 121, one-way valve signal processor 120, reversing valve signal processor 106, flow sensor 110, liquid level monitor 132 and central processing unit 151 respectively.
[0041] (8) A valve core, valve seat, valve body, and electromagnetic controller are respectively installed on the signal-controlled solenoid directional valve 107. When the valve core of the signal-controlled solenoid directional valve 107 is subjected to the impact force of unstable drilling fluid or aging, it is easy to generate excessive flow. When the flow sensor 110 senses the flow distortion, the flow sensor 110 transmits this signal to the central processing unit 151 through the directional valve signal processor 106. The central processing unit 151 performs self-identification and transmits the parameters that need to be adjusted to the directional valve solenoid device 108 through the directional valve signal processor 106. The directional valve solenoid device 108 drives the valve core to adjust the pressure required by the upper impeller 113.
[0042] (9) When the liquid level in the upper impeller chamber exceeds the specified liquid level, it indicates that there is hardware distortion. The liquid level monitor 132 will feed back this signal distortion to the central processing unit 151, and the central processing unit 151 will make the next adjustment.
[0043] (10) A signal-controlled solenoid check valve 123 is installed under the detection lens 122. The signal-controlled solenoid check valve 123 is equipped with a valve core, valve body, valve seat, solenoid controller, and temperature sensor 121. When the piston 118 moves to the right, if there is too much liquid around the signal-controlled solenoid check valve 123, the temperature sensor 121 will heat up. The temperature sensor 121 will send this signal to the central processing unit 151 through the check valve signal processor 120. The central processing unit 151 will make further signal adjustments and send this signal to the solenoid controller through the check valve signal processor 122 to adjust the valve core and eliminate liquid blockage.
[0044] (11) When the piston speed sensor on the piston 118 senses that the impeller speed is too slow, it indicates that the piston 118 is stuck in a certain place. The piston speed sensor will send this signal to the central processing unit 151 through the cam disk signal processor 103. The central processing unit 151 will send the appropriate adjustment parameters to the special motor 125 electromagnetic starting device through the cam disk signal processor 103 after self-identification. The electromagnetic controller will start the special motor 125 to eliminate the machine fault.
[0045] (12) When the speed sensor 111 on the upper impeller 113 detects that the impeller speed is too fast, it indicates that the detection lens 122 of the laser Raman detector cannot extract the spectrum of the sample, and further indicates that the force-bearing area of the impeller blades is too large. The speed sensor 111 transmits this distortion signal to the central processing unit 151 through the impeller disk power controller 115. The central processing unit 151 transmits an appropriate signal to the power controller, which uses the power of the controller to control the telescopic rod 114, thereby controlling the position of the upper impeller 113.
[0046] (13) When the central processing unit 151 is unable to handle all system distortions, it will send the distortion signal to the computer through the signal monitor, and at the same time send the distortion signal to the signal alarm to remind maintenance personnel to perform maintenance. The computer has a simulation system, and the workers will use the simulation system to further locate the distortion.
[0047] The working principle and flow of the reversing valve signal control system are as follows: Figure 6 As shown, when the flow sensor 110 senses that the flow rate to the impeller chamber is >30mL / s, the flow sensor 110 sends a fault signal to the reversing valve signal processor 106. The reversing valve signal processor 106 then sends the fault signal to the central processing unit 151. The central processing unit 151 provides data on the movement of the valve core of the signal-controlled solenoid reversing valve 107 and sends this data to the reversing valve signal processor 106. The reversing valve signal processor 106 controls the movement distance of the reversing valve solenoid device based on the newly received data. After correction, if the flow sensor continues to detect a signal fault, the system continues maintenance based on the directional valve signal processor 106, central processing unit 151, and directional valve spool. If the flow sensor still detects a fault after more than three maintenance attempts, the flow sensor 110 sends a fault signal to the directional valve signal processor 106, which then transmits the fault information to the central processing unit 151. The central processing unit 151 transmits the fault information to the computer via a signal monitor. Simultaneously, the signal monitor and signal alarm are connected; the signal alarm will sound as soon as a signal passes through the signal monitor, alerting the operator to resolve the fault.
[0048] The working principle and flow of the cam disc signal control system are as follows: Figure 7As shown, when the piston speed sensor detects a piston movement speed <3cm / s, it sends a fault signal to the cam plate signal processor 103. The cam plate signal processor 103 then sends the fault signal to the central processing unit 151. The central processing unit 151 provides the special motor 125 with the data to be started and sends this data to the cam plate signal processor 103. The cam plate signal processor 103 then starts the special motor 125 and corrects its rotation speed based on the newly received data. If the piston speed sensor continues to detect a fault signal after correction, the system continues to perform maintenance based on the data from the cam plate signal processor 103, the central processing unit 151, and the special motor 125. If the piston speed sensor still detects a fault after more than three maintenance attempts, it sends a fault signal to the cam plate signal processor 103. The cam plate signal processor 103 then sends the fault signal to the central processing unit 151. The central processing unit 151 transmits the fault information to the computer via a signal monitor. Simultaneously, the signal monitor and signal alarm are connected; the signal alarm will sound as soon as a signal passes through the signal monitor. Remind the operator to resolve the fault.
[0049] The working principle and flow of the impeller disk signal control system are as follows: Figure 8 As shown, when the speed sensor 111 senses that the rotational speed of the upper impeller 113 is greater than 20 r / s, the speed sensor 111 sends a fault signal to the impeller disk power controller 115. The impeller disk power controller 115 then sends the fault signal to the central processing unit 151. The central processing unit 151 provides data on the length to be released by the telescopic rod 114 and sends this data to the impeller disk power controller 115. The impeller disk power controller 115 controls the amount of electricity released based on the newly received data, thereby controlling the length to be released by the telescopic rod 114 and changing the force-bearing area of the impeller. After correction, if the speed sensor 111 continues to detect a signal fault, the system will continue maintenance based on the data from the impeller disk power controller 115, the central processing unit 151, and the telescopic rod 114. If the speed sensor 111 still detects a fault after more than three maintenance attempts, it will send a fault signal to the impeller disk power controller 115. The impeller disk power controller 115 will then transmit the fault information to the central processing unit 151. The central processing unit 151 will transmit the fault information to the computer via the signal monitor. Simultaneously, the signal monitor and the signal alarm are connected; the signal alarm will sound as soon as a signal is detected by the signal monitor, alerting the operator to resolve the fault.
[0050] The working principle and flow of the one-way valve signal control system are as follows: Figure 9As shown, when the temperature sensor 121 senses that the residual liquid in the detection lens cavity is >190°C, the temperature sensor 121 sends a fault signal to the check valve signal processor 120. The check valve signal processor 120 then sends the fault signal to the central processing unit 151. The central processing unit 151 provides the data on the movement of the check valve core and sends this data to the check valve signal processor 120. The check valve signal processor 120 controls the movement distance of the check valve solenoid device on the valve core based on the newly received data. After correction, if temperature sensor 121 continues to detect a signal fault, the system continues maintenance based on the one-way valve signal processor 120, central processing unit 151, and one-way valve core. If temperature sensor 121 still detects a fault after more than three maintenance attempts, it sends a fault signal to the one-way valve signal processor 120. The one-way valve signal processor 120 then transmits the fault information to the central processing unit 151. The central processing unit 151 transmits the fault information to the computer via a signal monitor. Simultaneously, the signal monitor and signal alarm are connected; the signal alarm will sound as soon as a signal passes through the signal monitor, alerting the operator to resolve the fault.
