Embodiment 1

[0025] Embodiment 1 provides an intelligent hydraulic pulse jet vibration drilling device, and its structure will be described in detail below.

[0026] refer to figure 1 , the intelligent hydraulic pulse jet vibration drilling device includes a drilling tool body 1 .

[0027] The drilling tool body 1 is a hollow cylinder, and the top of the drilling tool body 1 is provided with an internal thread for connecting a drill pipe or a drill collar.

[0028] The middle part of the drilling tool body 1 is provided with a spacer ring device 6, and the spacer ring device 6 divides the drilling tool body 1 into an upper pulse jet part 11 and a lower vibration impact part 12.

[0029] The pulse jet part 11 is sequentially provided with a sealing ring 2, a guide body 3, an impeller device 4 and a self-oscillating nozzle 5 from top to bottom, forming a pulse jet passage for circulating drilling fluid.

[0030] refer to figure 2 , the upper part of the sealing ring 2 is provided with ex...

Abstract

The invention discloses an intelligent hydraulic pulse jet vibration drilling device, which includes a drilling tool body and an intelligent measurement and control system. The sensors include pressure sensor, triaxial acceleration sensor, dual axis inclination sensor and azimuth gamma spectrum logging tool while drilling. The intelligent hydraulic pulse jet vibration drilling device disclosed in the present invention can be self-adaptively adjusted according to the formation conditions, and adjusted to the most suitable pulse vibration frequency according to the characteristics of the rock at the bottom of the well, so as to improve the rock-breaking efficiency of the drill bit, thereby improving the efficiency of mechanical drilling. The speed ensures that the tool can better adapt to the formation, which not only improves the work efficiency, but also solves the problems that the tool cannot be self-adjusted in real time at the bottom of the well and the tool has poor adaptability to the formation.

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...
