摘要
对空气洗井技术在硬岩大直径钻井工程中的应用进行了初步分析,给出了空气洗井系统参数设计的计算模型,同时提出了3种空气洗井设计方案。该项技术可用于寒冷地区冬季施工作业,为硬岩大直径钻井工程洗井的研究进行了有益的探索。
The paper generally analyses the application of shaft flushing with compressed air to the large-diameter drilling on the hard rock,and offers the model for calculating the parameters of air shaft flushing system.In addition,it proposes three kinds of designing scheme of air shaft flushing,which can be applied to the construction in cold areas in winter.The paper conducts beneficial discussion for the study of shaft flushing for the large-diameter drilling on the hard rock.
