Abstract

The invention discloses an intelligent hydraulic pulse jet vibration drilling device. The intelligent hydraulic pulse jet vibration drilling device comprises a drilling tool body and an intelligent measurement and control system. The intelligent measurement and control system comprises a controller, a while-drilling azimuth gamma-ray spectrum logging instrument, a plurality of sensors and a wireless transmitter; the sensors comprise a pressure sensor, a three-axis acceleration sensor, a double-axis tilt angle sensor and the while-drilling azimuth gamma-ray spectrum logging instrument. According to the intelligent hydraulic pulse jet vibration drilling device, self-adaptive adjustment can be carried out according to stratum conditions, the most appropriate pulse vibration frequency can be adjusted according to the characteristics of well bottom rock, rock breaking efficiency of a drill bit is improved, therefore mechanical drilling speed is increased, and it is guaranteed that a tool can better adapt to the stratum; the working efficiency is improved, and the problems that the tool cannot be self-adjusted in real time at the bottom of a well, and the tool is poor in stratum adaptability are solved.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to an intelligent hydraulic pulse jet vibration drilling device. Background technique [0002] With the continuous development of drilling technology and the increase of proven reserves of oil and gas resources, drilling engineering is playing an increasingly important role. It has always been an important direction of drilling engineering to achieve drilling speed increase by optimizing speed-increasing tools. Through axial vibration shock To increase the ROP is a speed-increasing method that has been recognized and adopted for a long time. [0003] For a long time, researchers in relevant fields at home and abroad have conducted a lot of research on axial vibration impact drilling, and have designed many types of axial vibration impact drilling speed-increasing tools. As far as the current downhole vibration impact drilling methods are concerned, they can be divided int...
