摘要
对深孔小直径绳索取心钻进技术设计进行了简要分析,论述了钻孔结构设计和施工中的技术风险因素和钻孔安全问题。同时,对合理选用金刚石绳索取心钻头、提高绳索取心钻杆使用寿命及其评价方法提出了建议。
The paper briefly analyzes the technical design of wire-line core drilling for deep geological hole and discusses the borehole structure design,technical risk factors and drilling safety. At the same time,the suggestions are made on the reasonable selection of diamond wire-line core drilling bit,the improvement of service life of wire-line core drill pipe and the evaluation method.
