本文主要针对常规的气体钻井取心技术中常见的岩心收获效率非常低、气体钻头进入尺寸小及气体外形的岩心质量不高等相应难题,经由研究和改进气体钻井取心技术的取心工具、钻头结构、选用切削齿及气体钻井取心的相关工艺流程,研究出适应气体钻井的使用工具和配套取心工艺,期待本文的阐述能为我国的常规的气体钻井取心技术的应用提供有效参考和借鉴。
This paper is mainly aimed at the common core drilling gas coring technology common core harvesting efficiency is very low, the gas drill into the small size and gas shape of the core quality is not high and the corresponding problems, through the research and improvement of gas coring coring tools, bit Structure, the choice of cutting teeth and gas drilling coring related process, research and development of tools and supporting coring technology suitable for gas drilling, expectation of this article can provide an effective reference for the application of our country’s conventional gas drilling coring technology and Learn from
