Abstract

The invention relates to the technical field of oil drilling tools, in particular to an oil drill pipe with a protective structure and its processing technology. The oil drill pipe is detachably assembled with a wear-resistant casing on the periphery of the drill pipe body, and the wear-resistant casing The rod body is protected to improve the wear resistance of the drill pipe body and prolong the service life of the drill pipe body; the upper and lower adjacent oil outlet heads and oil inlet heads are fixed and installed through the end protection structure, and the fastening ring is fixed to the oil outlet head and the oil inlet head. The periphery of the oil inlet head is fastened and assembled to avoid oil leakage during the assembly and use of multiple drill pipe bodies. The fasteners further tighten the periphery of the oil outlet head and the oil inlet head to prevent the two drill pipe bodies from slipping after assembly; The oil drill pipe with protective structure has excellent stability and wear resistance, and the multiple drill pipe bodies are not easy to slip off after assembly, prolonging the service life; the processing technology obtains multiple oil drill pipes that are firmly connected to ensure the stability in the oil drilling process sex.

Description

technical field

[0001] The invention relates to the technical field of petroleum drilling tools, in particular to an petroleum drilling pipe with a protective structure and a processing technology thereof. Background technique

[0002] Oil drill pipes are usually used to connect surface equipment such as drilling rigs on the ground with drilling and grinding equipment or bottom hole devices at the bottom of the well, and cooperate with drill bits for drilling operations. In the field of oil production, oil drill pipe is one of the indispensable important tools in oil drilling operations. Since the depth of oil drilling is usually deep, as the drilling depth increases, it is necessary to use multiple drill pipes connected in sequence to ensure normal drilling operations. , and due to different geological conditions, the depth of some oil drilling can reach several thousand meters, and even the depth of oil drilling in some special areas can reach tens of thousands of meters; ...
