Problems solved by technology

[0002] The lithology and pressure system of the lower formations are relatively complex when oil drilling is drilled, the lower formations are poor in drillability, and the ROP is low. Some hydraulic impactors capable of volume crushing have high requirements for driving flushing fluid, and the use cost is too high and the practicability is poor

Abstract

The torsion impactor of the lever reversing valve of the present invention is composed of an upper casing, a manifold body and a lower connecting body. Connected with the manifold body, the inner wall of the upper housing is fixed with a diverter fixed plate, a reversing valve housing, a fixing plate and a lower gland in sequence from top to bottom, and a spacer ring is fixed in the upper housing of the upper part of the reversing valve housing , the liquid outlet at the bottom of the diverter corresponds to the liquid inlet of the reversing valve housing, and two centrally symmetrical throats are arranged at the liquid outlet at the lower end of the reversing valve housing, and the other end of the throat passes through The fixed plate is placed in the rotary hammer cavity formed between the fixed plate and the lower gland. The structure design of the torsion impactor of the lever reversing valve of the present invention is reasonable, and the use of the reversing piston mechanism makes the use of the whole mechanism more convenient. Ordinary drilling fluid can achieve the desired effect and reduce the cost of use.

Description

technical field [0001] The invention belongs to the technical field of petroleum operation equipment, and in particular relates to a torsion impactor for a lever reversing valve. Background technique [0002] The lithology and pressure system of the lower formations are relatively complex when oil drilling is drilled, the lower formations are poor in drillability, and the ROP is low. Some hydraulic impactors capable of volume crushing have high requirements for driving flushing fluid, and the use cost is too high and the practicability is poor. Contents of the invention [0003] The invention aims at overcoming the disadvantages of the prior art, and provides a torsion impactor for a lever reversing valve. [0004] The lever reversing valve torsion impactor of the present invention is composed of an upper casing, a manifold body and a lower connecting body. Connected with the manifold body, the inner wall of the upper housing is fixed with a diverter fixed plate, a rever...
