Description

Technical Field

[0001] The invention relates to the technical field of oilfield drilling equipment, in particular to a full-rotating eccentric cylinder push-type high-temperature resistant guide tool. Background Art

[0002] Steering devices play a vital role in oilfield drilling and are widely used in directional drilling, horizontal well drilling, and the control of complex wellbore trajectories. Existing steering technologies include conventional steering tools and dynamic steering systems. Some equipment, such as screw motors and elbows, mainly achieve directional adjustment through fixed angles or simple eccentricity, but their flexibility is limited in complex formations. In addition, with the increasing complexity of drilling tasks, intelligent steering equipment has also developed in real-time monitoring, data processing, and automated adjustment, but the technical cost is high and its applicability still needs to be further optimized. Existing steering devices have achieved improvements in accuracy and adaptability in some areas, but the performance stability and diversified requirements in complex environments are still not fully met.

[0003] First, existing technologies typically rely on a single-level control method for eccentricity adjustment in directional drilling equipment, making it difficult to balance large-scale directional adjustments with small-scale precision corrections. This single adjustment method exhibits significant limitations in complex geological conditions. For example, when rapid direction changes or refined trajectory corrections are required, the equipment often fails to meet operational requirements. This technical shortcoming not only affects the accuracy of the drilling trajectory but also limits the equipment's adaptability in variable formations, resulting in reduced drilling efficiency and increased operational difficulty.

[0004] Furthermore, traditional drilling equipment lubrication systems typically utilize a fixed-volume lubrication system, maintaining a constant lubricant release rate regardless of eccentricity. This inflexible lubrication method is prone to two issues during operation: insufficient lubrication, which leads to severe wear of the eccentric barrel and key components due to excessive friction during high-intensity operation; and excessive lubricant waste. Excessive lubricant release not only increases operating costs but can also negatively impact other equipment components. Furthermore, existing equipment lacks intelligent lubrication control, making it difficult to adapt to the harsh, high-temperature, and high-pressure downhole environment.

[0005] Finally, existing guidance equipment has significant deficiencies in the accuracy and real-time performance of eccentricity adjustment. Traditional guidance control mostly relies on manual operation or simple preset parameters, lacking the ability to accurately calculate and provide feedback on real-time eccentricity changes. This technical limitation can easily lead to guidance deviations in complex formation conditions, which in turn affects the accuracy of the drilling trajectory. Furthermore, due to the lack of data recording and analysis capabilities, traditional equipment struggles to optimize subsequent guidance operation plans based on historical data, resulting in low guidance adjustment efficiency and poor operational safety. This is particularly inadequate in scenarios requiring high-precision continuous guidance. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a fully rotating eccentric cylindrical push-type high-temperature resistant guiding tool, which solves the problems of insufficient flexibility of existing guiding tools in complex formations, low eccentric adjustment accuracy, and the inability of the lubrication system to intelligently adapt to eccentric changes.

The equipment can dynamically capture the eccentricity changes, combine the accumulated offset and lubrication requirements for calculation, and optimize the guiding adjustment scheme. At the same time, real-time data is transmitted to the ground display screen, which facilitates the operator to intuitively monitor and adjust the drilling parameters. This refined guiding control not only improves the adaptability in complex drilling environments, but also provides a scientific basis for subsequent operations through data recording and analysis functions, thereby improving the intelligence level and safety of the operation.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] Please see the attached Figure 1-Attached Figure 4 The embodiment of the present invention provides a fully rotating eccentric cylindrical push-type high-temperature resistant guide tool, comprising:

[0053] Housing 1, which serves as a protective shell for the device and is used to protect the internal structure;

[0054] a drill bit 2, which is disposed at the bottom of the housing 1 and is used for drilling operations;

[0055] An outer frame 4 is provided on the outer wall of the housing 1 and is used to protect delicate components;

[0056] A PLC module 22, which is arranged inside the outer frame 4 and is used for equipment control;

[0057] A driving mechanism 3 is provided on the top of the housing 1 and is used to drive the drill bit 2 to perform operation;

[0058] an eccentric cylinder 6 , which is disposed inside the housing 1 and is used to control the drilling angle of the drill bit 2 ;

[0059] An eccentricity control mechanism is provided inside the eccentric cylinder 6 and is used to adjust the degree of eccentricity according to needs;

[0060] An oil storage cylinder 16 is provided on top of the eccentric cylinder 6 and is used to store lubricating oil and to spray and deliver the lubricating oil through the pump body;

[0061] A counting mechanism is provided inside the eccentric cylinder 6 and is used to convert the eccentricity of the eccentric cylinder 6 into the number of revolutions for measurement;

[0062] The eccentricity control mechanism includes an electric push rod 8, which is arranged inside the eccentric cylinder 6. An eccentric block 9 is fixed to the output end of the electric push rod 8. Slide blocks 10 are fixed on the upper and lower sides of the eccentric block 9. The slide blocks 10 are all slidably connected to the inside of the eccentric cylinder 6. The inside of the eccentric cylinder 6 is rotatably connected to a threaded column 11 symmetrical in upper and lower directions. The threaded column 11 is threadedly connected to the inside of the slide block 10.

[0063] An electric push rod 2 12 is provided inside the eccentric block 19, and an eccentric block 13 is fixed to the output end of the electric push rod 2 12. Slide blocks 2 14 are fixed on the upper and lower sides of the eccentric block 13. The slide blocks 2 14 slide inside the eccentric block 19. The inside of the slide blocks 14 is threadedly connected to a threaded rod 2 15, and the threaded rod 2 15 rotates inside the eccentric block 9.

[0064] Specifically, when the equipment is performing a steering operation, to meet the requirement for precise control of the drilling angle, the electric push rod 18 first drives the eccentric weight 19, and the sliding action of the slider 10 causes the eccentric weight 19 to shift along a predetermined trajectory. This adjustment is mainly used to achieve a large range of directional eccentricity changes, providing a general adjustment direction for the overall steering. Subsequently, according to more precise steering requirements, the driving action of the electric push rod 2 12 controls the eccentric weight 2 13 to slide and shift along the slider 2 14 within a small range, thereby achieving fine-tuning and optimization of the offset angle. The synergistic effect of the dual eccentricity adjustment design not only enables rapid adjustment of the general direction, but also allows the eccentric angle to be adjusted to an extremely precise level through detailed control. When the drive mechanism 3 drives the rotating shaft 5 and the eccentric barrel 6 to rotate, the eccentric state of the eccentric barrel 6 directly affects the drilling angle of the drill bit 2, thereby changing the drilling direction. This dual-layer control design not only improves steering accuracy, but also enhances the adaptability of the equipment in complex formation conditions, ensuring that the drill bit 2 can accurately perform the drilling task of the target trajectory.

[0065] Please see the attached Figure 5 The counting mechanism includes a connecting rod 18, one end of the connecting rod 18 is rotatably connected to a swivel 20, the other end of the connecting rod 18 is provided with a detector 19, the outer wall of the swivel 20 is provided with a docking device 21 distributed in a ring array, there are multiple swivels 20, one end of the threaded column 11 and the threaded rod 2 15 are each provided with one for synchronous rotation, there are multiple connecting rods 18, and one is fixed inside the eccentric cylinder 6 and the eccentric block 9.

[0066] Specifically, during the process of the eccentric block 1 9 and the eccentric block 2 13 performing the offset adjustment, the slider 1 10 and the slider 2 14 driven by each will jointly drive the threaded column 11 and the threaded rod 2 15, so that the threaded column 11 and the threaded rod 2 15 drive the rotating ring 20 to rotate synchronously through the rotational motion; while the rotating ring 20 rotates, the connected docking device 21 will also rotate accordingly, and this rotation process will be captured in real time by the detector 19 and converted into a corresponding signal, and the number of rotations will be accurately calculated through continuous reception and processing of the signal; then, the number of rotations is analyzed by a preset formula, and the total offset generated by the eccentric block 1 9 and the eccentric block 2 13 is further converted; this design ensures the high-precision acquisition of offset data, provides refined parameter input for the guidance system, can significantly improve the flexibility and accuracy of the equipment in guidance operations, and enables it to achieve highly controllable guidance adjustments even under complex formation conditions, thereby completing drilling tasks more efficiently.

[0067] Please see the attached Figure 2 and attached Figure 6A water pump is provided inside the oil storage cylinder 16, and an overflow frame 7 is provided on the outer wall of the eccentric cylinder 6. The bottom of the oil storage cylinder 16 is communicated with the water trough opened inside the eccentric cylinder 6 and passes through to the position of the overflow frame 7. There are multiple oil storage cylinders 16 distributed in a ring array, and an interconnecting ring 17 is provided between the oil storage cylinders 16. A rotating shaft 5 is fixed to the output end of the driving mechanism 3, and the rotating shaft 5 is connected to the eccentric cylinder 6. The bottom end of the rotating shaft 5 is connected to the drill bit 2. A high-temperature resistant layer 24 is provided inside the outer frame 4, and a wear-resistant layer 23 is provided on the outer wall of the high-temperature resistant layer 24.

[0068] Specifically, after determining the offset, the PLC module 22 will accurately calculate the total amount of lubricating fluid required for the guiding operation based on the received offset data, and transmit the instruction to the oil reservoir 16; the oil reservoir 16 uses the built-in water pump system to transport the calculated lubricating fluid in an appropriate amount to the position of the overflow frame 7, effectively lubricating the moving parts of the eccentric cylinder 6, thereby greatly reducing the mechanical loss caused by friction and extending the service life of the equipment; at the same time, during the drilling operation of the drill bit 2, the wear-resistant layer 23 exhibits excellent wear resistance due to its carefully designed titanium alloy composite aluminum nitride coating, effectively resisting the wear of high-strength formations on the equipment; and the high-temperature resistant layer 24 significantly improves the heat resistance and heat conduction efficiency through the filling of graphene materials, quickly dissipates heat in high-temperature environments, and ensures the stable operation of the core components of the equipment; this systematic lubrication and protection design not only reduces the energy consumption of the equipment in complex working conditions, but also greatly improves the operating efficiency and reliability, providing important technical guarantees for long-term drilling.

[0069] Please see the attached Figure 7 , the PLC module 22 is electrically connected to the oil storage cylinder 16, the PLC module 22 is electrically connected to the detector 19, the PLC module 22 is electrically connected to the electric push rod 1 8, and the PLC module 22 is electrically connected to the electric push rod 2 12;

[0070] The PLC module 22 includes:

[0071] An input signal unit, which is used to receive the adjustment-related signals of the eccentric block 1 9 and the eccentric block 2 13, and the pulse signal element sent by the detector 19;

[0072] A data processing unit, which is used to comprehensively calculate the eccentricity of the eccentric block 1 9 and the eccentric block 2 13, the change in the number of revolutions measured by the cumulative detector 19, and transmit the result to the control unit;

[0073] A control unit, which is used to control the opening time and flow rate of the lubricating oil in the oil storage cylinder 16 according to the results calculated by the data processing unit;

[0074] Display and communication unit, which is used to transmit calculation results to the ground display screen and record the system operation status;

[0075] A data storage unit for recording historical data for lubricant usage statistics, drilling trajectory recording and subsequent analysis;

[0076] The data processing unit converts the eccentricity of the eccentric block 1 9 and the eccentric block 2 13 into the number of revolutions using the following formula:

[0077]

[0078] R outer =N outer ΔR outer

[0079] R inner =N inner ΔR inner

[0080] Among them, R total is the comprehensive eccentricity, θ is the angle between the eccentric block 1 9 and the eccentric block 2 13, R outer 、R inner are the total eccentricity of eccentric block 1 9 and eccentric block 2 13, N outer 、N inner The number of revolutions measured by the eccentric block 1 9 and the eccentric block 2 13 respectively;

[0081] The lubricant requirement can be calculated based on the total eccentricity using the following formula:

[0082] L=k·R total

[0083] Where L is the lubricant demand and k is the lubricant demand coefficient.

[0084] Specifically, the PLC module 22 integrates multiple functional units to ensure the efficiency and accuracy of the system in guiding operations; specifically, it includes the following components: First, the input signal unit is responsible for receiving the adjustment signals of the eccentric block 1 9 and the eccentric block 2 13 in real time, and transmitting the pulse signal captured by the detector 19; these signals are the key basis for the eccentricity calculation and lubrication control of the entire system; secondly, the data processing unit accurately calculates the cumulative number of detector 19 turns through a comprehensive analysis of the eccentricity of the eccentric block 1 9 and the eccentric block 2 13, and transmits the results to the control unit after processing, thereby realizing refined monitoring and dynamic adjustment of the eccentric movement; this unit ensures the efficiency of eccentricity adjustment, and provides accurate parameter support for lubrication and drilling operations. On this basis, the control unit dynamically adjusts the opening time and flow of the lubricating oil in the oil storage cylinder 16 according to the results provided by the data processing unit, and accurately delivers the lubricating oil to the required parts; through This mechanism can effectively reduce eccentric movement and friction loss during drilling, thereby extending the service life of the equipment and improving operating efficiency; at the same time, the display and communication unit transmits all calculation results to the ground display screen in real time through wireless or wired communication, so that the operator can grasp the system status at any time; in addition, the unit also records the operating parameters of the equipment, such as lubricant usage and drilling trajectory, providing basic data for subsequent optimization; finally, the data storage unit is responsible for saving the historical data of the system operation, including the total amount of lubricant usage, eccentric adjustment trajectory information and related operating parameters; these data can not only be used for subsequent analysis and equipment maintenance, but also provide a scientific basis for optimization and adjustment in complex working environments; through the organic collaboration of the above functional units, the PLC module 22 realizes efficient control and real-time response in guided operations, effectively improves the reliability and operation accuracy of the equipment, and provides strong technical support for drilling tasks under complex working conditions.

[0085] Working principle: When the equipment needs to perform a guiding operation, according to the guiding requirements, the electric push rod 18 drives the eccentric block 19 to offset along with the sliding of the slider 10, so that it has an eccentric change in a general direction. Then, according to specific needs, the electric push rod 2 12 drives the eccentric block 2 13 to slide along the slider 2 14 and then offset, and then the offset degree is slightly controlled. In this way, the eccentric direction is further controlled by the double offset setting. When the driving mechanism 3 drives the rotating shaft 5 and the eccentric cylinder 6 to rotate, the eccentricity of the eccentric cylinder 6 is controlled to change the drilling angle of the drill bit 2. At the same time, when the drill bit 2 is drilling, the corresponding wear-resistant layer 23 effectively performs wear-resistant operation through the titanium alloy composite aluminum nitride coating set by itself, and the high-temperature resistant layer 24 is filled with graphene. The eccentric block 19 and the eccentric block 2 13 are filled with heat, and the heat-proof and rapid heat dissipation effects are achieved. When the eccentric block 19 and the eccentric block 2 13 are performing offset operations, the slider 10 and the slider 2 14 driven by each of them will respectively drive the threaded column 11 and the threaded rod 2 15, so that the threaded column 11 and the threaded rod 2 15 can be driven by the rotating driving ring 20 to drive the docking device 21 set therein to rotate. During the rotation, the signal can be received by the detector 19, and the number of rotations can be calculated. The total amount of offset generated is then converted and measured through a formula, so as to perform more precise guidance settings. After determining the offset, the PLC module 22 will calculate the total amount of lubricant required, and then let the oil storage cylinder 16 input the lubricant to the position of the overflow frame 7 through the water pump, thereby reducing the loss caused by friction at the position of the eccentric cylinder 6.
