Description

Technical Field

[0001] This invention relates to the field of downhole testing instrument technology, and in particular to a probe with pump stop measurement function. Background Technology

[0002] The rotary steerable technology integrates drilling, logging, and reservoir engineering, allowing for simultaneous logging and identification of oil and gas layers during drilling operations. In existing technologies, rotary steerable tools in horizontal wells require measurements of wellbore inclination and azimuth. Each measurement necessitates activating the pump to power the generator within the tool, which generates electricity from the well fluid to power the measuring instrument and measure parameters. With increasing demands for drilling cycles and mechanical drilling speeds, supermotors are often added to the steerable system to provide stronger power to the rotating steerable device. To shorten drilling cycles, the rotary steerable system needs to be able to stop the pump for measurement during drilling, reducing the time spent repeatedly switching the pump on and off. However, current helical steerable systems lack this pump-stop measurement capability, failing to provide power to the measuring instrument when the pump is shut down. Therefore, to address these shortcomings, a probe with pump-stop measurement functionality is proposed. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner", "outer", "top", and "bottom" are based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this invention and to simplify the description. It is not intended to indicate or imply that the component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0026] like Figure 1-5 As shown, the present invention provides a probe with a pump stop measurement function, specifically comprising: The pressure-resistant cylinder assembly 19 includes a pressure-resistant cylinder 1910, with an upper connector and a lower connector at its upper and lower ends, respectively. The pressure-resistant cylinder assembly 19 serves as the main body of the device. After the various components of the device are installed on the pressure-resistant cylinder assembly 19, it is connected to the rotary guide device. As the rotary guide device operates, it is lowered into the well, protecting the internal components and preventing downhole pressure from directly acting on them, thus preserving their integrity. The pressure-resistant cylinder 1910 is cylindrical and is the main pressure-bearing part of the pressure-resistant cylinder assembly 19. After the various components are installed inside the pressure-resistant cylinder 1910, it is connected to the rotary guide tool and other downhole tools via the upper and lower connectors to form a complete tool string. A sensor 18 is installed inside the pressure-resistant cylinder 1910, and the sensor 18 is connected to the lower connector via a pin structure. The sensor 18 can detect and receive signals in the downhole environment and record the received signals. Depending on the model and type of the sensor 18 installed, it can measure and record various downhole environmental parameters during downhole operation. After the sensor 18 is connected to the lower connector via a pin structure, the lower connector connects to other downhole tools and transmits signals and energy through the pin structure. Only the pin structure needs to be adjusted before docking the tools; no additional wiring work is required, reducing the workload when connecting the device to other downhole tools. The pin structure includes a pin 15 and a pin holder 12 for mounting the pin 15. The pin holder 12 carries the pin and is inserted downward into the lower connector. The pin 15, as the medium for transmitting signals and energy, is installed in the pin holder 12 and then fixed inside the pressure-resistant cylinder 1910. At this time, the head of the pin 15 faces downward, and the tail of the pin 15 is connected to the components inside the pressure-resistant cylinder 1910 via wires. After connecting to other downhole tools through the lower connector, the head of the pin 15 extends out from the lower connector and docks with the downhole tool to complete the transmission of signals and energy.

[0027] A connecting sleeve 8 is provided between the top end of the pin holder 12 and the sensor 18. The top end of the connecting sleeve 8 is connected to the bottom end of the connecting sleeve 8 by a connecting bolt 17. The connecting sleeve 8 is used to connect the pin holder 12 and the sensor 18. The sensor 18 is connected to the pin holder 12 via a wire passing through the connecting sleeve 8 for signal and power transmission. It also serves as a buffer to prevent the sensor 18 and the pin holder 12 from being damaged by impact during downhole operation. A pin holder fixing sleeve 9 is provided between the bottom end of the connecting sleeve 8 and the top end of the pin holder 12 and is connected to the connecting sleeve 8. The pin holder fixing sleeve 9 is the same shape as the bolt. The pin holder fixing sleeve 9 passes through the pin holder 12 and fixes the pin holder 12 to the connecting sleeve 8 by threads, preventing the connecting sleeve 8 and the pin holder 12 from being separated by vibration and pulling the wire during downhole operation, and avoiding the impact of wire damage on the signal and energy transmission inside the device.

[0028] It should be noted that the pin seat 12 is stepped, wider at the top and narrower at the bottom. The bottom end of the pin seat 12 is inserted into the top end of the lower connector from top to bottom. The diameter of the stepped structure at the top of the pin seat 12 is usually larger than the inner diameter of the lower connector. When the pin seat 12 moves downward, the stepped structure at the top can contact the top end of the lower connector, thereby preventing the pin seat 12 from sliding down the lower connector and separating from the pressure cylinder assembly 19. At the same time, when the stepped pin seat 12 is connected to the connecting sleeve 8, the pin fixing sleeve 9 only needs to pass through the step at the top of the pin seat 12 to connect the pin seat 12 and the connecting sleeve 8 together, reducing the installation difficulty of the device. During the assembly process, the insertion depth of the pin seat 12 in the lower connector changes depending on the downhole tool connected to the lower connector. Therefore, an adjusting sleeve 10 is provided between the bottom end of the step of the pin seat 12 and the lower connector. Changing the height of the adjusting sleeve 10 adjusts the length of the pin seat 12 inserted into the lower connector. After the pin socket 12 falls into the lower connector, the adjusting sleeve 10 is positioned between the pin socket 12 and the lower connector to separate them and raise the position of the pin socket 12 to a suitable height. Depending on the required installation height of the pin socket 12, an adjusting sleeve 10 with the required model and width should be selected before assembling the tool.

[0029] Furthermore, after the pin holder 12 is lowered into the well along with the pressure-resistant cylinder 1910, an anti-rotation groove is provided on the inner wall of the lower connector and the outer wall of the pin holder 12. The two anti-rotation grooves are positioned correspondingly, and an anti-rotation key 16 is provided between the two anti-rotation grooves to fix the position of the lower connector and the pin holder 12. At this time, a portion of the anti-rotation key 16 is located in each of the two opposing anti-rotation grooves. Under the action of its own structure, the anti-rotation key 16 fixes the position of the pin holder 12 and the lower connector through the anti-rotation groove, preventing the pin holder 12 and the lower connector from rotating relative to each other due to vibration in the well. This avoids the pin holder 12 and the lower connector from twisting the wires in the device after rotation, which would affect the transmission of signals and energy in the device, thus improving the stability of the device's operation.

[0030] The pin holder 12 has an annular spring plate 13 between its outer wall and the lower connector. The spring plate 13 helps to straighten the pin holder 12. The spring plate 13 is fitted onto the outer wall of the pin holder 12 and is in a compressed state. During the installation or operation of the pin holder 12, if the pin holder 12 is tilted to one side by force, the spring plate 13 will contact and compress the inner wall of the lower connector. Under its own elasticity, the spring plate 13 pushes the pin holder 12 in the opposite direction, so that the direction of the pin holder 12 is always in the center of the lower connector. This helps to straighten the direction of the pin holder 12 and prevents the tip of the pin 15 installed on the pin holder 12 from being damaged by force if the pin holder 12 is tilted.

[0031] like Figure 1-2As shown, the pressure-resistant cylinder 1910 contains a plate-shaped frame 4, which has a battery mounting bracket 6 and a battery 11. The frame 4 is installed inside the pressure-resistant cylinder 1910 to provide space for the installation and fixing of other components within the device, reducing the installation difficulty of each component. Simultaneously, the plate-shaped frame 4 allows for the installation of different components on its front and rear sides, thus separating different working components, tools, and their corresponding wiring. This prevents the signal and power wires of various components and tools from becoming entangled and affecting the normal operation of the device underground, and avoids situations where tangled wires pull against each other or even short-circuit, improving the safety of the device. The frame 4 is equipped with a circuit board, which switches the working state of the battery 11 according to the working status. Typically, rotary steerable tools need to be equipped with downhole power generation equipment. The fluid in the well moves under the impetus of a surface pump or underground energy. When the flowing underground fluid passes through the downhole power generation equipment, it drives the equipment to generate electricity to power the device. However, to ensure stable power, the device is usually stopped and the pump is turned on when measuring data from the target formation, using the downhole power generation equipment to power the measuring tool. The battery 11 can store the electricity generated by the power generation equipment when the surface pump is turned on. When the device is lowered to the required measurement location, the circuit board controls the battery 11 to discharge and power the measuring tool. At this point, it is no longer necessary to stop the device and turn on the pump to power the measuring tool, thus enabling downhole pump-stop measurement work, shortening the drilling and measurement process of the rotary steerable tool, and improving work efficiency.

[0032] The battery mounting bracket 6 consists of a fixing plate 14 fixed to the frame 4. The fixing plate 14 has a battery slot that matches the shape of the battery 11. The fixing plate 14 is connected to the frame 4 by fixing bolts 23. After the fixing plate 14 is installed on the frame 4, the battery 11 is placed in the battery slot of the fixing plate 14, and then the fixing bolts 23 are tightened. At this time, the fixing plate 14 is clamped to the frame 4 by the bolts 23, fixing the battery 11 to the frame 4. The frame 4 has several bidirectional wire clips 3 evenly distributed, and several unidirectional wire clips 5 on both the front and rear sides of the frame 4. The unidirectional wire clips 5 have vertically penetrating wire holes. The bidirectional wire clips 3 consist of two unidirectional wire clips 5 symmetrically arranged on the front and rear sides of the frame 4. The bidirectional wire clips 3 roughly fix the direction of the wires on both sides of the frame 4, preventing the wires on both sides of the frame 4 from tangling and reducing the workload during device disassembly. The unidirectional line clip 5 further fixes the direction of the wires based on the bidirectional line clip 3. Before assembling the device, the number and position of the unidirectional line clip 5 and the bidirectional line clip 3 need to be determined according to the number of components installed on the front and rear sides of the frame 4 and the number of their wires.

[0033] It should be noted that the front and rear sides of the frame 4 are each provided with several screws 20 perpendicular to the frame 4, and the circuit board is fixed by the screws 20; each screw 20 is provided with a nut 22, and a washer 21 is provided between the nut 22 and the root of the screw 20. When installing the circuit board, the screw 20 is inserted into the fixing hole of the circuit board, and then the nut 22 is tightened on the screw 20 to complete the installation of the circuit board. The washer is used to cooperate with the nut 22 to increase the clamping area of ​​the nut 22 and the screw 20 on the circuit board, thereby improving the stability of the circuit board fixing. The top of the frame 4 is provided with a frame support base 1, and the bottom is provided with a frame fixing frame 7 to fix the frame 4. The frame support base 1 and the frame fixing frame 7 are in contact with the upper connector and the sensor 18 respectively, thereby clamping the frame 4 in the device and preventing the frame 4 from shaking in the pressure-resistant cylinder 1910 under force.

[0034] In addition, to improve the aesthetics of the device's interior and further protect the circuit boards, battery 11, and corresponding wires installed on the frame 4, a tubular protective tube can be added to the outside of the frame 4. The frame can be inserted into the protective tube to prevent liquid leaking into the device from contacting the electrical components on the frame 4, thereby improving the device's safety.

[0035] Normally, battery 11 receives and stores power when the downhole generator in the rotary guide tool is working. When the predetermined measurement position is reached, the downhole generator stops generating power as the pump stops. At this time, the voltage in the power line of the device is 0V, which is lower than the voltage of battery 11. At this time, the circuit board controls battery 11 to start and supply power to the devices in the well. The measuring equipment performs periodic measurements of the surrounding formation data according to the preset frequency and measurement time. When the measurement time ends, the circuit board controls battery 11 to stop supplying power and return to the previous working state.

[0036] In this invention, the upper connector includes a connecting rod 1905 and a main support base 1909. The connecting rod 1905 is installed at the top of the pressure-resistant cylinder 1910, and a plug socket 1901 is provided at the top of the connecting rod 1905. The main support base 1909 is located at the bottom of the connecting rod 1905. The connecting rod 1905 is used to connect the pressure-resistant cylinder 1910 to other downhole tools above it. The main support base 1909 is used to connect to the frame support base 1 at the top of the inner frame 4 of the pressure-resistant cylinder 1910 and to support the frame 4, further fixing the position of the frame 4. The plug socket 1901 is connected to the wires extending from the frame 4 via wires. When connecting to the downhole tools above, it is only necessary to insert the pins of the downhole tools into the plug socket 1901 and align them to align and connect the downhole tools with the wiring inside the device, thereby transmitting signals and energy.

[0037] A support rod 1906 is provided between the main support base 1909 and the connecting rod 1905. The top end of the support rod 1906 is connected to the plug socket 1901, and the main support base 1909 is installed at the bottom end of the support rod 1906. The support rod 1906 acts as a buffer between the connecting rod 1905 and the main support base 1909, reducing friction between them. After the top of the main support base 1909 is connected to the plug socket 1901, the top of the main support base 1909 abuts against the plug socket 1901. The main support base 1909 is installed at the bottom of the support rod 1906. It can transmit the downward pressure exerted on the plug socket 1901 after the downhole tool above is connected to the upper connector to the main support base 1909, preventing the main support base 1909 from moving upward under the action of vibration and its own inertia during downhole operation. At the same time, it can also use the force of the main support base 1909 moving upward to push the plug socket 1901 upward, so that the plug socket 1901 is more tightly and firmly connected to the downhole tool above.

[0038] It is important to note that the main support base 1909 is equipped with a shock-absorbing mechanism on its side wall. During underground operation, the tool often vibrates after contacting the underground soil. This shock-absorbing mechanism can mitigate the vibration of the tool, thereby preventing the frame 4 and the components mounted on the frame 4 from loosening or even being damaged due to underground vibration. The shock-absorbing mechanism consists of multiple vertically and evenly arranged disc springs 1912 between the main support base 1909 and the support rod 1906. When the device comes into contact with the underground formation, causing the tool to vibrate, the vibration is transmitted to the main support base 1909 through the frame 4 and the frame support base 1. At this time, the vibration is transmitted to the disc springs 1912. Under the action of its own elasticity, the disc springs 1912 undergo elastic deformation of stretching or compression, and return to their original shape after the vibration ends. This maintains the stability of the frame 4 and the components mounted on the frame 4, ensuring the integrity of the device during underground operation and extending the service life of the device.

[0039] In addition, in order to improve the sealing of the device and prevent the fluid downhole from flowing into the pressure-resistant cylinder 1910 through the gaps between the components, sealing rings 2 are respectively provided between the outer walls of the skeleton support seat 1 and the skeleton fixing frame 7 and the inner wall of the pressure-resistant cylinder 1910.

[0040] like Figure 3-5As shown, an adjusting piece 1902 is provided between the plug socket 1901 and the connecting rod 5 to adjust the height of the plug socket 1901. When the upper connector is connected to other downhole tools, the connectors used for different downhole tools have different structures, and the required height of the plug socket 1901 varies. The adjusting piece 1902 is located below the plug socket 1901 and between it and the connecting rod 5, and can raise the height of the plug socket 1901 to meet the needs of the device connection. In actual installation, after determining the required installation height of the plug socket 1901, adjusting the thickness and number of adjusting pieces 1902 can change the installation height of the plug socket 1901, thereby achieving the effect of adjusting the plug socket 1901. The adjusting piece 1902 is usually made of metal and is relatively hard. To prevent the adjusting piece 1902 from scratching the connecting rod 1905 during operation, a rubber pad 1903 is usually provided below the adjusting piece 1902. The rubber pad 1903 can replace the connecting rod 1905 in contact with and wear against the adjusting plate 1902, thus preventing wear on the connecting rod 1905. Simultaneously, the rubber pad 1903 can also fill the surrounding gaps between the adjusting plate 1902 and the connecting rod 1905, further improving the sealing performance of the device.

[0041] Within the connecting rod 1905, a plug positioning seat 1913 is provided below the plug socket 1. The plug positioning seat 1913 is used to cooperate with the plug socket 1901. After the device is connected to the downhole tool connecting rod, the connecting part of the downhole tool extends into the plug socket 1901 and contacts the plug positioning seat 1913. At this time, the plug positioning seat 1913 will guide the connecting part in the correct direction and cooperate with the plug socket 1901 to fix the connecting part that has penetrated into the plug socket 1901, making the signal transmission between the device and other downhole tools more stable.

[0042] It should be noted that a baffle 1908 is provided below the support rod 1906 and the connecting rod 1905; a retaining spring 1911 is provided on the outer wall of the support rod 1906, which retracts inward to clamp the support rod 1906. The initial diameter of the retaining spring 1911 is usually smaller than the outer diameter of the support rod 1906. Under its own elasticity, the retaining spring 1911 will retract inward and clamp the support rod 1906, further fixing the position of the support rod 1906 and preventing the support rod 1906 from moving up and down under force during downhole operation, affecting the stability of the connection between the plug socket 1901 and the upper downhole tool. The baffle 1908 is fixed to the bottom of the support rod 1906 so that the bottom of the support rod 1906 and the connecting rod 1905 forms a flat contact surface with the skeleton support base 1, preventing the skeleton support base 1 from being damaged due to excessive local pressure when supporting the skeleton 4 under force.

[0043] An outer sleeve 1904 is provided between the outer sleeve 1911 and the inner wall of the connecting rod 1905. A positioning pin 1907 is provided between the outer sleeve 1904 and the sleeve 1911 to fix their positions. The outer sleeve 1904 is usually made of a soft or highly elastic material such as rubber or plastic to prevent the force received by the support rod 1906 downhole after the sleeve 1911 clamps the support rod 1906 from being directly applied to the inner wall of the connecting rod 1905, thus avoiding damage to the connecting rod 1905 and the sleeve 1911. The outer sleeve 1904 will wear out in place of the sleeve 1911 and the connecting rod 1905. After the work is completed, the outer sleeve 1904 can be replaced for the next operation. The outer sleeve 1904 and the retaining spring 1911 are each provided with a positioning groove. The two positioning grooves are in corresponding positions and the positioning pin 1907 is inserted into the two positioning grooves at the same time to fix the positions of the outer sleeve 1904 and the retaining spring 1911, preventing relative rotation between the outer sleeve 1904 and the retaining spring 1911.

[0044] The probe with pump stop measurement function provided by this invention can perform pump stop measurement during downhole operations. The specific operation process of the device is as follows: Step 1: After assembling the device according to its structure, connect it to the tool string of the downhole tools. At this time, the device is connected to other short circuits on the rotary steerable tool through the upper and lower connectors to transmit signals and energy. The rotary steerable device performs drilling and measurement work according to the operating program set inside the device.

[0045] Step 2: Upon reaching the measurement location, the circuit board controls the battery to supply power and initiates pump-stop measurement. During this process, after the device reaches the measurement location, the surface drive pump shuts down, and the downhole power generation equipment stops generating electricity. The voltage in the conductor is zero, lower than the battery voltage. After the circuit board detects the voltage in the conductor, it controls the battery to start and supply power to the components inside the device. At this time, the measuring tool, after receiving power from the battery, runs downhole measurements according to the pre-set working sequence.

[0046] Step 3: After the measurement work is completed, start the ground operating pump and restore the battery's operating status. At this point, after the measurement work is completed, the circuit board controls the battery to stop supplying power and starts the ground pump. The underground power generation equipment gradually resumes operation as the pump is turned on, providing power to the device.

[0047] Step 4: Repeat steps 2 and 3 until the drilling measurement work is completed.
