Statistics and analysis of drilling efficiency of geostress monitoring holes

摘要:

随着地应力监测台站的不断建设，地应力监测孔钻探施工技术在实践中不断得到改进。本文简要介绍了地应力监测孔的钻探技术要求、钻探设备选型及钻进工艺，对施工完成的地应力监测孔的钻进时间和钻进效率进行了系统的统计和分析。通过分析研究，总结了影响地应力监测孔钻进效率的几个因素，包括监测孔选址、钻进过程管理、钻进工艺和试验配合等。并针对这些影响因素，提出了通过强化钻进过程管理、利用技术套管和分级扩孔等关键技术、加强开孔和测斜等重要环节的技术管理、做好试验配合等措施提高钻进效率的建议，为今后实施类似钻探工程项目提高钻进效率提供了参考依据。

Abstract:

With the continuous construction of geostress monitoring stations， the drilling technology of geostress monitoring holes has been continuously improved in practice. This paper briefly introduces the drilling technical requirements， selection of drilling equipment and drilling technology of geostress monitoring holes， systematic statistics and analysis were conducted on the drilling time and drilling efficiency of the completed geostress monitoring holes. Through analysis and research， several factors affecting the drilling efficiency of geostress monitoring holes are summarized， including location selection for monitoring holes， management of drilling process， drilling technology， and test cooperation， etc. According to these influencing factors， suggestions were put forward to improve drilling efficiency by strengthening management of drilling process， utilizing key technologies such as technical casing and graded reaming technology， strengthening technical management of important links such as drilling and inclination measurement， and doing well in test cooperation， it provides reference bases for the implementation of similar drilling projects in the future to improve drilling efficiency.
