摘要
Abstract
The use of DTH hammer air foam technology construction of water source well, signiifcantly improve the mechanical speed, shorten the drilling cycle;hole cleaning and cooling conditions, prolong the service life of bit, save the bit rate;the use of air hammer bit drilling pressure, small, low speed, small torque, inclining prevention effect is good;can effectively to avoid lost circulation of downhole complicated conditions, conducive to environmental protection.关键词
