Description

Technical Field

[0001] This invention relates to the field of oil drilling, specifically to a pressure boosting and speed-up device for oil drilling. Background Technology

[0002] Extractable oil and gas resources are buried in deep strata, and drilling is gradually developing towards deep and ultra-deep wells. However, drilling in deep and hard strata presents challenges such as slow drilling speed, long drilling cycle, and high drilling cost.

[0003] Existing drilling pressurization technologies include surface pressurization and downhole pressurization. However, surface pressurization has high requirements for the sealing of the entire pressurization pipeline, and field applications require matching with the corresponding drilling system, resulting in poor safety. Furthermore, the pressure loss of mud flowing in the pipeline is large, the energy efficiency ratio is poor, and the pressurization capacity is limited.

[0004] Downhole pressurization includes static pressurization and jet pressurization. For example, Chinese utility model patent with authorization publication number CN215761497U discloses a pressurization device for drill pipe, which includes a first power device connected to the drill pipe collar and a second power device that is rotated relative to the drill bit, and also includes a control device connected between the first power device and the second power device. Under the power of drilling fluid flow, the first power device and the second power device rotate in opposite directions. The second power device pressurizes part of the drilling fluid and discharges it through the drill bit, thus achieving pressurization without power.

[0005] Downhole boosting typically involves a complex reversing valve system and numerous flow channels. These numerous flow channels can cause larger particles of mud and sand to enter the boosting chamber, affecting the service life of the booster pump. Summary of the Invention

[0006] To avoid the aforementioned problems in the prior art, the purpose of this invention is to provide a booster and speed-up device for oil drilling, which can increase drilling speed while reducing energy consumption and wear, and extending the service life of the equipment.

[0007] To address the aforementioned problems, the present invention provides the following technical solution: a pressure boosting and speed-up device for oil drilling, comprising an impact head, drill pipe, a pressure boosting component, a main crushing component, a secondary crushing component, and an auxiliary pumping component; the bottom of the drill pipe is connected to the impact head; the main crushing component is disposed within the drill pipe, and includes a drive assembly and a main crushing roller, the main crushing roller being connected to the drive assembly; the secondary crushing component includes a secondary crushing roller driven by the drive assembly, the main crushing roller and the secondary crushing roller being configured together to form a crushing structure for crushing drilling fluid; the auxiliary pumping component is disposed on the secondary crushing component, and the crushed drilling fluid is guided by the auxiliary pumping component to the pressure boosting component disposed within the impact head.

[0008] The invention is further configured such that the oil drilling booster and speed-up device also includes a mounting frame, which is detachably mounted on the inner wall of the drill pipe.

[0009] The present invention is further configured such that the drive assembly includes a drive motor, a shaft and a worm gear, a connecting rod and a turbine; the output end of the drive motor is connected to one end of the shaft, and the other end of the shaft is connected to the worm gear; the shaft extends into the mounting frame, and the worm gear at the end of the shaft is rotatably connected to the mounting frame;

[0010] The first connecting rod extends into the mounting frame and is rotatably connected to the mounting frame. The first connecting rod is provided with the turbine, which meshes with the worm gear. The end of the first connecting rod away from the mounting frame is connected to the main crushing roller.

[0011] The present invention is further configured such that the drive assembly includes a drive gear, which is disposed on a connecting rod between the main crushing roller and the turbine and rotates synchronously with the connecting rod.

[0012] The drive motor drives the worm gear connected to the shaft to rotate, and the turbine meshes with the worm gear to drive the turbine to rotate. The turbine drives the connecting rod and the main crushing roller to rotate together, and cooperates with the secondary crushing roller to assist in crushing the input drilling fluid, preventing large particles of mud and sand from entering the pressurization chamber and affecting the service life of the pressurization components.

[0013] The present invention is further configured such that the secondary crushing component further includes a second connecting rod and a driven gear; the second connecting rod extends into the mounting frame and is rotatably connected to the mounting frame, the driven gear is provided on the second connecting rod, and the driven gear meshes with the driving gear.

[0014] The present invention is further configured such that the end of the connecting rod two away from the mounting frame is connected to the secondary crushing roller, and the position of the secondary crushing roller is matched with the position of the main crushing roller.

[0015] The present invention is further configured such that the auxiliary liquid pumping component includes a rotating rod, multiple sets of negative pressure impellers, a negative pressure box, an input pipe, and a discharge pipe; one end of the rotating rod is connected to the connecting rod 2, and the other end is connected to multiple sets of negative pressure impellers, the negative pressure impellers extend into the negative pressure box, and the negative pressure box is mounted on the mounting frame; the input pipe and the discharge pipe are connected to the negative pressure box.

[0016] The present invention is further configured such that the negative pressure impellers are arranged in a ring at equal intervals along the rotating rod with the rotating rod shaft as the center.

[0017] The rotating rod rotates synchronously with the connecting rod 2, driving multiple sets of negative pressure impellers to rotate from inside the negative pressure box to generate negative pressure. The negative pressure acts on the filtered drilling fluid through the input pipe and is transported to the booster pump through the discharge pipe to distribute and deliver the drilling fluid, maintain borehole stability, control formation pressure, and improve drilling efficiency.

[0019] The invention is further configured such that both the pressure sensor and the booster pump are connected to the controller signal. The booster pump is used to compress and pressurize the conveyed drilling fluid, and then convey the pressurized drilling fluid to the high-pressure nozzle position of the impact head.

[0020] The pressurization and speed-up method of the present invention is applicable to various drilling conditions, whether it is a deep well, a shallow well, a hard formation or a soft formation, and can improve drilling speed and increase drilling operation efficiency.

[0021] In summary, the beneficial effects of the above-mentioned technical solution of the present invention are as follows:

[0022] This invention, through its interconnected primary and secondary fracturing components, significantly reduces energy consumption and wear compared to traditional methods of increasing drill bit speed and drilling pressure, thereby lowering drilling costs. The auxiliary fluid extraction component rotates synchronously with the secondary fracturing component, driving multiple sets of negative pressure impellers to rotate within the negative pressure tank, generating negative pressure. This negative pressure acts on the filtered drilling fluid through the input pipe and is then transported to the booster pump through the discharge pipe, distributing and delivering the drilling fluid to maintain borehole stability, control formation pressure, and improve drilling efficiency.

[0023] This invention increases the drilling fluid pressure by incorporating a pressurization component, thereby improving the drilling efficiency of the drilling tool and ultimately increasing the drilling speed. Furthermore, the pressurization component is equipped with a pressure sensor to detect the drilling fluid pressure. By adjusting the drilling fluid pressure, the drilling speed can be precisely controlled and flexibly adjusted according to different drilling conditions. Attached Figure Description
