Abstract

The invention provides a hydraulic impact drill bit with rolling teeth. The hydraulic impact drill bit comprises a rotary disc track, a drill bit body, a first spiral blade, a rotary disc, a flow limiting disc, an impact hammer, a spring, a second spiral blade, a straight rod, a hollow cavity, the rolling teeth, a chain, a connecting gear, a drill bit body, a protrusion, a hollow bevel gear, a sealing ring, a water hole, cutting teeth, a bearing, a small gear, a large gear and bevel teeth. According to the hydraulic impact drill bit, by rotating the rolling teeth, heat and abrasion are reduced, the service life of the drill bit is prolonged, an impact tool is installed, and the well drilling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of drilling engineering, in particular to a hydraulic percussion drill bit with rolling teeth. Background technique [0002] With the development of oil and gas drilling to deep layers, the drillability of rocks in deep formations is poor, resulting in a decrease in ROP, increased tool wear, and increased drilling costs. The problem of drilling in hard formations has become increasingly prominent, and efficient rock-breaking technology has become a research hotspot at present. The quality of rock-breaking efficiency will determine the final benefits of drilling projects. At present, percussion rotary drilling technology is one of the effective methods to solve the problem of slow drilling speed in hard formations, and the percussion rotary drill bit has been proved in field tests that it can improve drilling efficiency without requiring additional energy loss, so it has gradually become the method for increa...
