Drilling Technology of JK-1 Deep Hole at Deep Exploration Experimental Base in Xingcheng of Liaoning

Abstract:

In order to verify the research results of field geological exploration and geophysical prospecting, 4 holes, more than 1500 meters in depth, were constructed at deep detecting experimental base in Xingcheng of Liaoning Province. The design depth of JK-1 is 1800 meters, but its actual depth is 1750 meters. By drilling through the basement of Yangjiazhangzi synclinal basin, the complete core of North China type Paleozoic strata in western Liaoning Province was achieved. The quality indexes of recovery rate and borehole verticality have reached high quality requirements. The smooth implementation of JK-1 will provide technical support for the subsequent drilling construction.
