Development and Field Test of the Same-Frequency Different-Phase Compound Impact Tool
A same-frequency different-phase compound impact tool was developed to improve the rock-breaking efficiency of PDC bits in hard formations, increase the penetration depth of cutters, and eliminate the “stick-slip” phenomenon of the downhole bit.The ...
