摘要
介绍了基于无线电磁波传输的随钻伽马测井系统在顺煤层瓦斯预抽采钻孔受控钻进施工中的应用,主要介绍了系统组成、工作原理及其应用开展情况。在山西伯方煤矿对电磁波随钻伽马测井系统进行了煤矿井下随钻应用,结果表明:仪器能够满足随钻测量的实际生产需求,指导钻具沿煤层钻进,有效提高钻进效率,降低施工成本。
This paper introduces the application of gamma logging system while drilling based on wireless electromagnetic wave transmission in controlled drilling of gas pre-drainage borehole along coal seam,and the analytic process includes the composition,working principle and application of the system.The system is applied in Bofang Coal Mine,the results show that the system can meet the actual production requirements of measurement while drilling,ensure drilling along coal seam,effectively improve drilling efficiency and reduce construction cost.
