煤矿近水平定向钻孔测斜技术

Deviation Measuring Technology Used in Quasi-horizontal Directional Drilling Hole at Coal Mines

摘要:

在进行煤矿近水平钻孔的测量时，对于测斜仪的选型及输送方法都有别于垂直钻孔。以ZJS-1型钻孔监测系统和CQ-1A型单点测斜仪为例，介绍了煤矿近水平孔测斜技术。

Abstract:

While measuring quasi-horizontal drilling holes, probe types and the ways to put them down the holes differ from those used in vertical drilling holes. The Deviation measurement technology used in quasi-horizontal holes at coal mines was introduced taking ZJS-1 Borehole Monitoring System and CQ-1A Single Shot Inclinometer as samples.
