Description

[0002] Rotary steerable systems are advanced equipment that highly integrates drilling technology, logging technology, and reservoir engineering technology. By measuring geological and engineering parameters in real time and using drilling control methods, it ensures that the drilling trajectory can accurately pass through the reservoir to reach the optimal position. This system not only has the ability to identify oil and gas layers while drilling, but also has a powerful steerable function. It is a high-tech technology in the drilling field in the 21st century. In practical applications, rotary steering systems can significantly improve drilling efficiency and accuracy, especially in complex formations. However, in the development of shale oil and shale gas, due to the special characteristics of these formations, existing intelligent steering systems often face the problem of low rotation speed during operation, which directly affects drilling speed and construction efficiency, limiting their large-scale application. To address the issue of low operating speed of the intelligent guidance system, the conventional approach is to add a straight motor to the rear end of the intelligent guidance system to increase drilling speed.

The wire enters the drive assembly through this channel and passes through the wire channel provided on the outer wall of the lower drive shaft 17 to exit the speed-up device for geological tools.
[0030] The following is a detailed description of the actual working scenario of a speed-up device for geological tools.
[0031] The geological tool is assembled with a speed-up device and placed in the rotary guide tool, and connected in series with the rotary guide tool. Typically, the speed-up device for the geological tool needs to be installed in the middle and front section of the rotary guide tool. During the operation of the rotary steering tool, drilling fluid enters from the left end of the acceleration device for geological tools. First, it passes through the guide element 3 in the switching short-connector frame 1. The guide element 3 guides the flow direction of the drilling fluid, ensuring the fluid enters subsequent components via the optimal path. The drilling fluid continues to flow, passing through the length adjuster 4 and the rotary connector 5. The turbine rotor 21 on the outer wall of the extension rod 6 begins to rotate due to the impact of the drilling fluid, initially accelerating it. The initially accelerated drilling fluid then enters the anti-drop connection assembly, the annular section between the anti-drop connector 7 and the anti-drop frame 8. The channel allows the drilling fluid to continue flowing. The drilling fluid enters the motor assembly, where the rubber stator 10 and rotor 11 further accelerate the drilling fluid. The spiral structure design of the rotor 11 optimizes the flow path of the drilling fluid, enabling it to achieve higher speeds in a short time. The drilling fluid then enters the universal guide 16, which transforms the liquid in the annular liquid channel into a columnar structure, thereby pressurizing the drilling fluid. The pressurized drilling fluid enters the drive assembly through the inclined through-hole in the universal guide 16 and is ejected from the center of the drive assembly.
[0032] It is understood that the various embodiments mentioned above in this invention can be combined with each other to form combined embodiments without violating the principle and logic. Due to space limitations, this invention will not elaborate further.
[0033] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.
[0034] This invention provides a speed-up device for geological tools. By placing the speed-up device in series with a rotary steerable tool, the flow direction of the liquid entering the device is guided by a guide member 3 at the inlet end. The drilling fluid passing through the center of the device is accelerated by an extension rod 6 and several turbine rotors 21 on its outer wall. The drilling fluid is further accelerated by a motor assembly, which further increases the speed of the drilling fluid. The liquid channel in the universal guide 16 at the outlet end pressurizes and discharges the accelerated liquid. By accelerating the drilling fluid through its internal structure, this device increases the mechanical rotational speed of the drill bit in the rotary steerable tool without increasing the overall torque of the drill string, effectively improving the mechanical drilling speed of the rotary steerable tool and thus significantly increasing construction efficiency.
