Large diameter coring technology for shale oil exploration in Songliao Basin

摘要:

大口径取心技术为页岩油勘探提供了准确可靠的岩心地质资料，本文主要介绍了川7-4型、KT-194型大口径常规取心钻具和ZYVC型大口径密闭取心钻具的技术参数以及这3种取心钻具在松页油2井大口径取心中的应用情况，通过对取心钻具、取心钻头、取心钻进参数的调整和改进，机械钻速大幅度提高，岩心质量优良，提高了钻进效率，为页岩油勘探取心提供了丰富经验和技术方法。

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.
