沈北煤田的地层松散,岩石遇水膨胀,钻进时常漏水、掉块、挤夹钻,有时甚至埋钻,测井仪器放不下去。我队为了高速优质拿下沈北煤田,组织了工人、干部、技术人员三结合研究小组,经过多次试验,用合理选择冲洗液方法,初步解决了钻进中的地层坍塌、掉块、漏水等问题,基本上保证了钻探工程顺利进行。2009钻机用这一方法在1973年5月份进尺2868米,6月份又突破了5千米,实现了月进尺5032米。
Shenbei coalfield loose stratum, the rock water expansion, drilling often leaks, dropped pieces, pinch drill, and sometimes buried drilling, logging equipment can not let go. In order to win the Shenbei coalfield with high speed and high quality, our team organized a three-in-one research team consisting of workers, cadres and technicians. After several tests, the method of rational choice of flushing fluid was adopted to initially solve the problems of formation collapse, And other issues, basically ensure the smooth progress of drilling. 2009 drilling rig with this method in May 1973 footage of 2868 meters, in June and broke through 5 km, achieved a monthly footage of 5032 meters.
