本文根据常规气体钻井取心技术中岩心收获效率低、质量不高、以及气体钻头进入尺寸小等一系列问题,经过对取心工具、钻头结构、选用切削齿及相关工艺的改进,从而研制出一套完整的操作工具和取心工艺方法用以专门适应气体钻井。
Based on a series of problems such as low efficiency of core harvesting, low quality and small size of gas drill entering into the coring technology of conventional gas drilling, this paper developed a series of problems such as coring tools, bit structure, cutting teeth and related technology A complete set of operating tools and coring process to specifically adapt to gas drilling.
