Problems solved by technology

[0002] In recent years, with the development and development of shale oil and gas, geothermal resources, etc., drilling technology has also been rapidly improved and developed. The existing downhole power drilling tools can no longer meet the speed and development of drilling, and there is an urgent need for a downhole power tool. Tools can improve drilling efficiency, shorten the drilling cycle, and increase the ROP of new tools
The current downhole dynamic drilling tools have no axial impact function, the ROP is not high, the working life is not long, and the tripping time is increased.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0026] Such as figure 1 As shown, a single-screw rotary impact microseismic transmitter includes a filter bypass assembly 1, a filter safety assembly 2, a hydraulic assembly 3, and a transmission assembly connected by self-locking tapered threads from top to bottom. Into 4 and rotary micro seismic launcher assembly 5, the launcher uses drilling fluid to remove solid particles harmful to the motor in the filter bypass assembly 1. The filter safety assembly 2 ensures that the launcher can work safely and efficiently. At the same time, the nozzle split method is used to reduce the pressure drop of the motor. At the same time, the jet method assists in breaking the rock. The hydraulic assembly 3 converts the kinetic energy of the water into mechanical energy to form the eccentric movement of the hydraulic core 32 through the transmission assembly 4 The eccentric m...

Abstract

The invention relates to drilling equipment, in particular to a single spiral spin micro-seismic emitter which comprises a filter bypass assembly, a filter safety assembly, a hydraulic drive assembly, a drive assembly and a spin micro-seismic emission assembly which are sequentially connected from top to bottom. The assemblies are connected with each other in a threaded manner and conveniently assembled and disassembled. When drilling fluids pass the emitter, solid particles are filtered in the filter bypass assembly, the filter safety assembly protects safe and efficient operation of the emitter, operating pressure drop of a motor is reduced, and rock crushing is assisted by a jet method. The spin micro-seismic emission assembly forms axial impact in an impact source emitting mode, reacting force of a spring is applied to an emission impact body, and an axial impact function is achieved. Impact frequency can be changed by adjusting the rotating speed of an emission connecting rod, and the emission connecting rod can be used with motors with different rotating speeds.

Description

Technical field [0001] The invention relates to a drilling equipment, in particular to a single spiral rotary impact microseismic transmitter. Background technique [0002] In recent years, with the development and development of shale oil and gas and geothermal resources, drilling technology has also been rapidly improved and developed. The existing downhole power drilling tools can no longer meet the speed and development of drilling, and there is an urgent need for downhole power. Tools can improve drilling efficiency, shorten drilling cycle, and improve the new type of drilling speed. The current downhole power drilling tool has no axial impact function, the mechanical drilling speed is not high, and the working life is not long, which increases the time for tripping. Summary of the invention [0003] In order to solve the above problems, the present invention provides a single spiral rotary impact microseismic transmitter. The short section of the transmitter can be installe...
