摘要
为了满足煤矿井下随钻方位伽马测井在顺煤层钻进地质导向的应用需求,设计开发了矿用钻孔深度测量仪,为随钻方位伽马测井的数据资料解释提供精确深度数据支持。从组成、工作原理、结构设计、现场试验等几个方面介绍了钻孔深度测量仪在随钻方位伽马测井中的应用情况。通过在地面勘探孔及煤矿井下实钻孔中的试验,表明钻孔深度测量仪测量的深度数据稳定、可靠,可以满足煤矿井下方位伽马测井对钻孔深度测量的需求。
To meet the practical demand of the azimuth gamma logging tool while drilling in the geological guidance of the drilling along the seam in the ground mine,a drilling depth measuring equipment for coal mine was designed and developed,it could provide the accurate depth data of the borehole to support the azimuth gamma logging data interpretation.This paper introduces the application of depth measuring equipment in azimuth gamma logging while drilling from the aspects of composition,working principle,physical design and field test.Through the test of the exploration hole on the ground and the drilling in coal mine underground,it shows that the measurement data of the depth measuring equipment is stable,reliable and could meet requirement of the azimuth gamma logging while drilling in coal mine underground.
