摘要
介绍集贤煤田东辉勘查区,在钻探施工中漏水,引起孔壁坍塌,采用不分散低固相泥浆加入堵漏剂、DTR材料及改性沥青泥球堵漏配合的处理方法,起到了护壁堵漏的作用,提高了钻探经济效益。
The method of using non - dispersive low solid - phase mud joining with plugging agent, DTR materials and modified asphalt ball plugging to treat the drilling water leakage and causing the hole wall collapsing in Jixian Donghui coal exploration area, played the role of protecting the shaft wall, plugging the hole and raised the economic efficiency of drilling.
