江苏某盐矿勘探孔钻探技术分析

Technical analysis of exploration drilling holes in a salt mine in Jiangsu

为了确保在盐岩地层顺利钻探勘探孔,结合钻探工艺优化的原则对江苏地区某盐矿勘探孔施工进行了技术分析,根据地质报告设计孔身结构采用三级口径成孔并配备塔式钟摆钻具组合进行施工,通过确定合理的钻进工艺、采取严格的规程参数,顺利完成了该勘探孔施工任务。

In order to obtain a smooth exploration hole in the area of gypsum formation, technical analysis of the construction of a salt mine ex- ploration holes drilled in Jiangsu province based on the principles of process optimization. According to the geological report designed body structure would be used three bore holes into the hole and tower pendulum BHA. By the drilling process parameters determined reasonably and taking strict procedures, the exploration holes construction tasks were successfully completed.
