| Abstract: | The large diameter coring technology provides accurate and reliable core geological data for shale oil exploration. This paper mainly introduces the technical parameters of both Chuan7-4 and KT-194 conventional coring tools and ZYVC sealed coring drill tools, as well as the application of the core drilling tools in Well Songyeyou-2.In the process of coring, the technical measures were constantly improved which has contributed to the mechanical drilling rate, the core quality and the drilling efficiency, providing rich experience and methods for shale oil exploration and coring. |
