辽宁兴城深部探测实验基地JK-1深孔钻探技术

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

摘要:

为了验证野外综合地质和地球物理探测研究成果，在辽宁兴城深部探测实验基地施工了4口1500 m以深的科学钻孔。其中，JK-1孔设计孔深1800 m，实际孔深1750 m。该钻孔钻穿了杨家杖子向斜盆地基底，取得了完整的辽西地区华北型古生代地层岩心。岩心采取率和钻孔垂直度等质量指标均达到优质孔的要求。JK-1孔的顺利实施为后续钻孔的施工提供了技术保障。

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.
