Description
Technical Field
[0001] This invention relates to the field of oil drilling technology, specifically to a high-performance, fully hydraulic shock absorber with intelligent control. Background Technology
[0002] In the field of oil drilling, with the continuous increase in drilling depth and difficulty, stuck drill bits occur frequently, seriously affecting extraction efficiency and cost control. In underground drilling operations, due to complex geological conditions and significant differences in rock hardness and structure, drill bits are highly susceptible to getting stuck during drilling, preventing the drill string from rotating and advancing normally. This not only halts the drilling progress but can also damage drilling tools, increasing maintenance costs and extending the drilling cycle.
[0003] Currently, there are many drawbacks to the tremor devices used on the market to solve stuck drill bit problems. Traditional mechanical tremor devices rely on the direct collision of mechanical parts to generate impact force. However, in actual operation, this method has low energy transfer efficiency and limited impact force. Due to the limitations of the mechanical structure, it is difficult to provide sufficient force to free the drill bit when facing strong stuck resistance under complex geological conditions. Moreover, frequent collisions of mechanical parts are prone to wear, resulting in high equipment failure rates, high maintenance costs, and seriously affecting the continuity and stability of drilling operations. Although some hydraulic tremor devices have improved in terms of impact force, they have serious deficiencies in hydraulic oil management and intelligent control. On the one hand, their hydraulic oil circulation system design is not reasonable enough, and it is impossible to achieve efficient and orderly flow of hydraulic oil. During the tremor process, the hydraulic oil cannot flow precisely into the designated area, resulting in low energy utilization efficiency and failing to fully utilize the advantages of the hydraulic system. On the other hand, these hydraulic tremor devices lack intelligent control functions and cannot adjust the tremor parameters in real time according to the actual situation of stuck drill bit. Because there is no system for effectively monitoring and analyzing key parameters such as hydraulic oil pressure, flow rate, and drill pipe displacement, operators find it difficult to accurately grasp the working status of the shock absorber and make timely and reasonable adjustments. This results in the shock effect failing to meet expectations, severely impacting the efficiency and reliability of drilling operations. Furthermore, existing shock absorbers generally cannot flexibly control the hydraulic oil flow rate. They cannot provide sufficient hydraulic energy when needed, and cannot guarantee smooth hydraulic oil flow when not needed, further reducing their effectiveness in resolving stuck drill bits. Therefore, a high-performance, fully hydraulic shock absorber with intelligent control is needed. Summary of the Invention

[0012] Preferably, an impeller is fixedly connected to the outer wall of the second gear, and the outer wall of the impeller is provided with fan blades. The impeller is disposed inside the first infusion tube.
[0013] Preferably, the system for intelligent control of the high-performance fully hydraulic shock absorber includes: The sensor is disposed on the outer wall of the inner tube, and the sensor includes a pressure sensor, a displacement sensor, and a flow sensor; A central controller, located on the top side of the sealing plate, is used to dynamically generate shock parameter commands based on sensor data. A servo motor is mounted on the outer wall of the outer tube to drive the lifting of the outer tube and the inner tube.
[0014] Preferably, the pressure sensor is installed on the outer wall of the inner tube to monitor the hydraulic oil pressure in real time; the displacement sensor is installed at the sliding connection between the slide rod and the scraper ring to detect the displacement and movement frequency of the scraper ring; and the flow sensor is installed inside the liquid pipe and connected coaxially with the impeller to calculate the hydraulic oil flow rate by measuring the impeller speed.
[0015] Working Principle: Upon encountering a stuck drill, the servo motor mounted on the outer wall of the outer sleeve immediately activates. Driven by its powerful force, the outer sleeve and inner sleeve rise together. At this moment, the firmly stuck drill generates a counterforce, causing the drill rod and transmission rod to slowly move downwards along the inner wall of the inner sleeve. This movement further propagates, causing the sealing plate and piston head to also begin their downward stroke along the inner wall of the inner sleeve. During the downward movement of the sealing plate, spring one between it and the top side of the circular fixed plate is compressed, storing elastic potential energy; simultaneously, when the piston head presses down, it also compresses spring two between the base and itself. As the sealing plate continues to move downwards, the hydraulic oil originally sealed between the sealing plate and the rubber ring flows through pre-designed oil holes to the area between the piston head and the oil inlet plate under the pressure difference, continuously replenishing the lower chamber with hydraulic oil. Meanwhile, as the piston head moves downward inside the inner tube, the connected traction rope is tightened, which in turn drives the scraper ring to move flexibly along the outer wall of the inner tube and the outer wall of the slide rod, efficiently scraping the hydraulic oil adhering to the outer wall of the inner tube into the lower chamber, avoiding waste and residue of hydraulic oil. When the outer tube and inner tube stop rising, the previously compressed springs one and two return to their original position due to their elasticity. Combined with the pressure difference generated by the flow of hydraulic oil in the upper and lower chambers, the sealing plate begins to rise upward on the inner wall of the inner tube. During this process, the elastic rope tightly pulls the plug, allowing it to slide smoothly on the outer wall of the limit rod until it precisely blocks the inner wall of the oil inlet cylinder. At this point, the hydraulic oil in the lower chamber can only enter the upper chamber through the single channel of the oil inlet on the outer wall of the oil inlet plate, which pushes open the rubber ring. The flow rate of the hydraulic oil will suddenly increase, and under the drive of the powerful hydraulic energy, the outer tube, inner tube, and base drive the impact head to strike the bottom of the drill rod with great force, bringing a powerful shock to the drill bit and helping it get out of the stuck drill bit situation. In addition, as the distance between the sealing plate and the rubber ring gradually decreases, the traction effect of the elastic rope on the plug disappears. At this time, the spring three on the outer wall of the limit rod pushes the plug out from the inner wall of the oil inlet cylinder through the compression and reset, allowing the hydraulic oil in the lower chamber to flow smoothly into the upper chamber through the inner wall of the oil inlet cylinder. At the same time, the relative displacement change between the sealing plate and the inner wall of the top of the inner tube causes the connecting rod to swing back and forth between the sealing plate and gear one, driving gear one to rotate on the inner wall of the inner tube. With the help of the meshing relationship with gear two, the impeller inside the infusion tube one also rotates at high speed. The rotating impeller provides a driving effect, and together with infusion tube two, it orderly guides the hydraulic oil in the upper chamber between the sealing plate and the rubber ring into infusion tube one, and then precisely flows into the cavity between the sealing ring and the scraper ring along infusion tube three. Driven by the hydraulic oil, the scraper ring rises steadily, scraping the hydraulic oil in the cavity into the lower chamber between the piston head and the oil inlet plate, creating favorable conditions for the servo motor to more easily lift the inner tube and the outer tube. The system is also carefully equipped with a variety of advanced sensors and an intelligent central controller.Sensors are neatly mounted on the outer wall of the inner tube to detect minute changes in hydraulic oil pressure. Displacement sensors are precisely positioned at the sliding connection between the slide bar and the scraper ring, providing real-time and accurate monitoring of the scraper ring's displacement and frequency. Flow sensors are located inside the infusion pipe, coaxially connected to the impeller, and accurately measure the dynamic information of hydraulic oil flow based on impeller speed. The central controller, located on top of the sealing plate, dynamically generates the most suitable shock parameters based on the continuously collected data from the sensors. This coordinates closely with all components within the system, ensuring the entire process from stuck drill bit to successful shock removal is accurate, stable, reliable, efficient, and smooth.
[0016] This invention provides an intelligently controlled, high-performance, fully hydraulic shock absorber. It offers the following advantages: 1. This invention uses a servo motor to drive the outer and inner tubes to lift in tandem. Combined with the flow of hydraulic oil and the restoring effect of the spring, the device can generate a strong shock force, helping the drill bit to quickly get out of a stuck situation, and significantly improving the efficiency and reliability of drilling operations.
[0017] 2. This invention uses the relative displacement change between the sealing plate and the inner wall of the top of the inner tube to drive the connecting rod to swing, drive the gear to rotate, and then make the impeller rotate at high speed. In conjunction with the infusion tube, the hydraulic oil in the upper chamber is orderly introduced and accurately flows into the designated cavity, and then scraped into the lower chamber by the scraper ring, creating favorable conditions for subsequent lifting.
[0018] 3. This invention achieves flexible switching of the hydraulic oil in the lower chamber into the upper chamber channel by controlling three pairs of plugs: elastic rope and spring. When needed, it accelerates the hydraulic oil flow rate and provides strong hydraulic energy, while ensuring smooth flow of hydraulic oil into the upper chamber when not needed.

Detailed Implementation
[0021] 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.
[0022] Example: Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 6 This invention provides an intelligent control high-performance fully hydraulic shock absorber, comprising: A base 1 has a drill rod 2 slidably connected to its middle end. The connecting assembly includes a connecting head 16 fixedly connected to the bottom side of the base 1, a connecting head 27 fixedly connected to the bottom end of the drill rod 2, the connecting head 27 being disposed on the outer wall of the connecting head 16, an impact head 28 fixedly connected to the middle end of the bottom side of the base 1, a spring 28 disposed on the outer wall of the drill rod 2, a piston head 5 fixedly connected to the outer wall of the top end of the drill rod 2, a transmission rod 3 fixedly connected to the top side of the drill rod 2, a sealing plate 4 fixedly connected to the top end of the transmission rod 3, a spring 13 disposed at the middle end of the transmission rod 3, a slide rod 19 fixedly connected to the top side of the base 1, and an oil scraper ring 15 slidably connected to the outer wall of the slide rod 19. Specifically, in the event of a stuck drill, the servo motor mounted on the outer wall of the outer sleeve 11 immediately starts. Under its powerful drive, the outer sleeve 11 and the inner tube 10 are lifted together. At this moment, the stuck drill generates a reverse force, causing the drill rod 2 and the transmission rod 3 to slowly move down along the inner wall of the inner tube 10. This movement is further transmitted, causing the sealing plate 4 and the piston head 5 to also begin their downward stroke along the inner wall of the inner tube 10. During the downward movement of the sealing plate 4, the spring 13 between it and the top side of the circular fixed plate 25 is compressed, storing elastic potential energy; at the same time, when the piston head 5 presses down, it also compresses the spring 18 between the base 1 and itself.
[0023] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 5 The inner tube 10 is fixedly connected to the top side of the base 1. A circular fixing plate 25 is fixedly connected to the middle end of the transmission rod 3. The oil inlet assembly includes an oil inlet plate 22 fixedly connected to the outer wall of the circular fixing plate 25. A rubber ring 23 is provided on the top side of the oil inlet plate 22. An oil inlet is provided on the outer wall of the oil inlet plate 22. An oil hole is provided at the middle end of the inner tube 10. An oil inlet cylinder 21 is fixedly connected to the inner wall of the upper oil hole. The elastic component includes a limiting rod 30 fixedly connected to the outer wall of the oil inlet cylinder 21. The plug 27 is slidably connected to the outer wall of the limiting rod 30. The outer wall of the limiting rod 30 is provided with a spring 31. An elastic rope 24 is connected between the inner wall of the plug 27 and the sealing plate 4. A sealing ring 14 is fixedly connected to the inner wall of the inner tube 10. The traction assembly includes a guide roller fixedly connected to the inner wall of the lower oil hole. A traction rope 20 is connected between the top side of the piston head 5 and the top side of the oil scraper ring 15. The traction rope 20 is provided on the outer wall of the guide roller. An outer sleeve 11 is provided on the outer wall of the inner tube 10. Specifically, as the sealing plate 4 continues to move downwards, the hydraulic oil originally sealed between the sealing plate 4 and the rubber ring 23 flows through the pre-designed oil hole to the space between the piston head 5 and the oil inlet plate 22 under the action of pressure difference, continuously replenishing the lower chamber with hydraulic oil. At the same time, due to the downward movement of the piston head 5 inside the inner tube 10, the connected traction rope 20 is tightened, which in turn drives the scraper ring 15 to move flexibly along the outer wall of the inner tube 10 and the outer wall of the slide rod 19, efficiently scraping the hydraulic oil adhering to the outer wall of the inner tube 10 into the lower chamber, avoiding the waste and residue of hydraulic oil.
[0024] Please see the appendix Figure 3 Appendix Figure 5 and attached Figure 7 The connecting rod 6 is rotatably connected to the top side of the sealing plate 4. The gear set includes a gear 7 rotatably connected to the inner wall of the inner tube 10, and a gear 8 rotatably connected to the top inner wall of the inner tube 10. The gear 7 and gear 8 are meshed. The top of the connecting rod 6 is rotatably connected to the outer wall of the gear 7. The top side of the sealing plate 4 is fixedly connected to the infusion tube 12. The infusion assembly includes an infusion tube 12 fixedly connected to the top side of the sealing plate 4, and an infusion tube 9 fixedly connected to the top side of the infusion tube 12. The outer wall of the sealing ring 14 is fixedly connected to the infusion tube 26, and the top of the infusion tube 26 is fixedly connected to the outer wall of the infusion tube 9. The outer wall of the gear 28 is fixedly connected to the impeller 29, and the impeller 29 is provided with fan blades on its outer wall. The impeller 29 is located inside the infusion tube 9 for transporting hydraulic oil between the inner tube 10 and the outer tube 11. Specifically, when the outer tube 11 and inner tube 10 stop rising, the previously compressed springs 13 and 18 return to their original position due to their elasticity. Combined with the pressure difference generated by the flow of hydraulic oil in the upper and lower chambers, the sealing plate 4 begins to rise upwards along the inner wall of the inner tube 10. During this process, the elastic rope 24 tightly pulls the plug 27, allowing it to slide smoothly along the outer wall of the limit rod 30 until it precisely blocks the inner wall of the oil inlet cylinder 21. At this point, the hydraulic oil in the lower chamber can only enter the upper chamber through the single channel of the rubber ring 23, which is the oil inlet port on the outer wall of the oil inlet plate 22. The flow rate of the hydraulic oil will suddenly increase, and under the powerful hydraulic energy, the outer tube 11, inner tube 10, and base 1 drive the impact head 28 to strike the bottom of the drill rod 2 with great force, bringing a strong and powerful shock to the drill bit and helping it get out of the stuck drill bit situation. In addition, as the distance between the sealing plate 4 and the rubber ring 23 gradually decreases, the traction effect of the elastic rope 24 on the plug 27 disappears. At this time, the spring 31 on the outer wall of the limiting rod 30, after being compressed and reset, pushes the plug 27 out of the inner wall of the oil inlet cylinder 21, allowing the hydraulic oil in the lower chamber to flow smoothly into the upper chamber through the inner wall of the oil inlet cylinder 21. Simultaneously, the relative displacement between the sealing plate 4 and the inner wall of the top of the inner tube 10 causes the connecting rod 6 to oscillate back and forth between the sealing plate 4 and gear 7, driving gear 7 to rotate on the inner wall of the inner tube 10. Through its meshing with gear 8, the impeller 29 inside the infusion tube 9 also rotates at high speed. The rotating impeller 29 provides a driving effect, working with the infusion tube 12 to orderly guide the hydraulic oil in the upper chamber between the sealing plate 4 and the rubber ring 23 into the infusion tube 9, and then precisely flow along the infusion tube 26 into the cavity between the sealing ring 14 and the scraper ring 15. Driven by hydraulic oil, the scraper ring 15 rises steadily, scraping the hydraulic oil in the cavity into the lower chamber between the piston head 5 and the oil inlet plate 22, creating favorable conditions for the servo motor to more easily lift the inner tube 10 and the outer tube 11.
[0025] Please see the appendix Figure 8 and attached Figure 9 As another aspect of the present invention, the present invention provides an intelligent control high-performance fully hydraulic shock absorber system, comprising the following systems: The sensors are installed on the outer wall of the inner tube 10, and include pressure sensors, displacement sensors and flow sensors. A central controller is located on the top side of the sealing plate 4 to dynamically generate shock parameter commands based on sensor data. A servo motor is installed on the outer wall of the outer tube 11 to drive the lifting of the outer tube 11 and the inner tube 10.
[0026] A pressure sensor is installed on the outer wall of the inner tube 10 to monitor the hydraulic oil pressure in real time.
