Abstract

The invention relates to a method and device for changing a power impact motor in the drilling engineering technology and the process technology, in particular to a method and device of a liquid powerimpact motor. According to the method and device of the liquid power impact motor, the upper portion of the drilling power motor is connected with a drilling tool, and the lower portion of the drilling power motor is connected with a PDC drill bit. Especially, the drilling power motor is directly connected to the drill bit and a drilling rod, no external force is needed, only drilling mud circulating pressure drives the drilling power motor, the drill bit is assisted in rock breaking, repeated rock debris cutting is reduced, a drill bit stick-slip phenomenon is eliminated, and the rock breaking efficiency is improved.

Description

technical field [0001] The invention relates to a method and a device for changing a power impact motor in drilling engineering technology and process technology, in particular to a method and a device for a liquid power impact motor. Background technique [0002] At present: There are many types in the United States and Canada, mainly including: air-medium rotary impact motors, low-density medium rotary impact motors, and mechanical rotary impact motors. The principles of these impact motors are different, and the adaptability is quite different, all of which require special processing for various power motors. Due to the complex structure, special treatment is carried out, which increases the manufacturing cost and time. Disadvantages of aerodynamic rotary impact motors: 1. Insufficient power. 2. The scope of application is small. The low-density medium rotary impact motor has a complicated structure and is unfavorable for maintenance. The tool is too long, which is no...
