摘要
在地质勘探中,经常遇到钻孔涌水,导致钻进施工困难,为了解决这个难题,在某探矿孔钻探施工中,通过对冲洗液、高压注浆、多层套管分级泄流等措施进行研究,保证高承压水下钻探施工作业的安全。
In geological exploration,drilling water gushing is often encountered,which leads to difficulties in drilling construction.In order to solve this problem,in the drilling construction of a prospecting hole,the safety of high pressure underwater drilling operation is ensured by studying the measures such as flushing fluid,high-pressure grouting and multilayer casing graded discharge.
