摘要
在地质条件不稳定的岩土层山地钻井,容易出现塌井。通过为山地钻机配备跟管钻具,有效地解决了这一问题。本文介绍了跟管钻具的工作原理和特点,并进行了试验,取得了良好的实验效果。
Drilling in unstable rock and soil layers of mountain conditions often prone to collapse. Equipped with the pipe drill rigs proved to be an effective solution for this driling problem. This article describes the working principle and characteristics of the rig.
