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.
