摘要
QDT-MWD无线随钻测斜仪是一种比较先进的井眼轨迹跟踪控制设备,是优质高效地完成大位移井钻井施工的基本务件,介绍了该测斜仪的结构、工作原理及其对工作条件的要求。QDT-MWD无线随钻测斜仪在海南区块大位移定向井中的应用结果表明,该仪器能加快钻井速度,提高井身质量。该区块井身质量舍格率100％,剖面符合率99％,中靶率100％。
The QDT-MWD is an advanced well trajectory tracing instrument which is the necessary condition for completing drilling extended reach well with high quality. This paper presents its design, mechanisms and condition requirements. Its field applications to such wells in Hainan block show that it can speed up ROP, improve well profile with 100% qualified wellbore and 99% well profile, 100% striking target ratio.
