High-frequency torsion and axial bidirectional impactor

Abstract

The invention relates to a high-frequency torsion and axial bidirectional impactor, and belongs to the technical field of oil and gas field well drilling and well repairing tools. The high-frequency torsion and axial bidirectional impactor comprises a housing, a connector, an alignment bearing, a turbine shaft, an upper hammer body and a lower hammer body, wherein the connector is mounted at one end of the housing in a threaded manner; the lower hammer body is glidingly mounted at the other end of the housing through an end cover and a buffer spring, and the turbine shaft is mounted in the housing through a nut; a turbine rotor and a stator are mounted at one end of the turbine shaft, and the upper hammer body is mounted at the other end of the turbine shaft. By adopting the high-frequency torsion and axial bidirectional impactor, contact stress between a drill bit and rock can be effectively increased, and crack expansion in a broken pit can be effectively improved, so that the rock breaking efficiency of the drill bit can be improved; the problems that when a conventional rotating well drilling mode is adopted, the well drilling efficiency is degraded, the service life of the drill bit is shortened, the well drilling period is long and the cost is high when a hard stratum is encountered can be solved; the high-frequency torsion and axial bidirectional impactor has active popularization meanings in well-drilling efficiency improvement and well drilling cost reduction.

Description

technical field [0001] The invention relates to a high-frequency torsional and axial two-way impactor, which belongs to the technical field of oil and gas field drilling and workover tools. Background technique [0002] Known as the "blood of the world economy", petroleum has always played a pivotal role in my country's industrial and economic development and is an important pillar of my country's national economy. In recent years, the global oil market has been sluggish, falling from more than 90 US dollars per barrel to more than 20 US dollars, but the cost of exploitation has increased year by year. With the depletion of shallow oil and gas resources in my country, oil and gas exploration will inevitably develop in the direction of deeper and harder formations . When the traditional rotary drilling method encounters hard formations, the drilling efficiency will be reduced, the life of the drill bit will be shorter, the drilling cycle will be longer, and the cost will be h...

AI Technical Summary

Problems solved by technology

When the traditional rotary drilling method encounters hard formations, the drilling efficiency will be reduced, the life of the drill bit will be shorter, the drilling cycle will be longer, and the cost will be higher; therefore, effectively increasing the drilling rate is an urgent problem in today's drilling engineering; and to explore Newer and more efficient rock-breaking drilling technology, increasing drilling speed, reducing drilling cost, and shortening the exploration and development cycle are urgent needs for the development of drilling technology
