Conveying mechanism and method of upper drilling platform and lower drilling platform of drilling pipe used for petroleum drilling

Abstract

The invention discloses a conveying mechanism of an upper drilling platform and a lower drilling platform of a drilling pipe used for petroleum drilling, which comprises a pipe distribution frame (1), a conveying device (2) and a rail (3), wherein the conveyance of the drilling pipe from the pipe distribution position to a small mouse hole of the drilling platforms is completed through the matching action of the pipe distribution frame (1), the conveying device (2) and the rail (3). The invention has simple operation. Through the mechanical integrated design, a large amount of traditional manual assistance conveyance operation is avoided, a drilling tool is efficiently and safely conveyed to the specified small mouse hole position from the automatic pipe distribution frame, and at the same time, when the drilling pipe is taken back and recovered form the small mouse hole, the operation can be completed through reverse operation according to the method steps by the mechanism.

Description

technical field [0001] The invention belongs to the field of equipment for oil drilling, and in particular relates to a conveying mechanism and method for drilling pipes used for oil drilling up and down the drill floor. Background technique [0002] With the development of the national economy, the demand for oil and natural gas is increasing, which requires that the speed and efficiency of exploration and development need to be improved. During the drilling process, it is necessary to continuously increase the drilling pipe. The traditional method is that the drilling pipe is in front of the drilling rig. On both sides of the ground, the casing and the drill pipe are arranged separately. The wire rope of the winch is manually wound on one end of the drill pipe, and the hemp rope wound on the other end is guided by manual traction. Loosen the hemp rope used for manual traction and guidance, and the winch will send the drill pipe to the drill floor along the anchor road and ...

AI Technical Summary

Problems solved by technology

[0003] It can be seen that this kind of drill pipe and casing work requires manual cooperation and adopts the steel index method. The degree of automation is low, there are many open-air operations, and there are many restrictions due to natural factors. The labor intensity is high, the efficiency is low, and there are potential safety hazards. The requirement of increasing the speed of the drilling rig, to some extent, this method has greatly hindered the drilling efficiency
