As stick slip vibration easily causes drilling tool failure, and rate of penetration is caused to reduce.In addition, can larger journey using air drilling drilling
Degree improves rate of penetration, but easily causes down hole problem in the case of formation water output, and gas drilling corollary equipment
More, cost is relatively large.
In view of the above problems, having attempted multiple types of tools both at home and abroad, certain speed-increasing effect, medium-high frequency torsion are achieved
Impact class tool accounts for the leading position of speed-raising tool.Field experiment and theoretical research show that such tool can be attached to drill bit
Add high-frequency torsional pulse power, assist drill bit broken rock, reduce the stick-slip phenomenon of drill string, improve rate of penetration, reduces drilling cost, it is real
The economic benefit of existing bigger, while also better ensuring that the safety of drilling well, but torsion impact device is complicated, process and assemble
Difficulty is big.
