摘要
Combined the wire-line coring and hydro-hammer technologies,the drilling speed of wire-line coring hydro-hammer technology increases 30%-150% than that of traditional wire-line coring drilling,especially in hard,brittle and slipping formations.The paper introduced the application of wire-line coring hydro-hammer technology in Liberia and discussed the application effects.
