地热井钻进岩屑录井技术方法探讨

A Discussion on the Sieve Residue Logging Techniques and Methods in Geothermal Well Drilling

深井牙轮钻进不取芯的岩屑录井,是一项技术性很强的工作,关系到能否采全、采准深井岩层资料和标本。本文根据我院近年来地热井施工实践,总结出一套较为成型的录井技术方法,供从事此项工作的技术人员参考。

The sieve residue logging during the deep-well non-coring roller boring, is a job of high technology, and critical to whether the deep-well stratigraphic data and specimens can be collected completely and correctly. This paper sums up a set of the logging techniques and methods on the basis of the team＇s operation practices in geothermal well drilling in recent years, which can provide references for technical workers engaged in such work.
