地热勘探地质录井几个注意的问题

Some Problems to be Noted in Geological Logging During Geothermal Prospecting

目前,北京市地热井的性质以探采结合为主,首先是"探",其次是"采"。地质录井是地热勘探过程中获得原始资料最直接的方式,地质录井成果的质量对成井质量起着至关重要的作用。本文以北京市顺义区后沙峪地区顺后热一8地热井为例,针对地质录井工作中需要注意的岩样采集、钻进异常、地球物理测井和试井问题,进行了初步探讨。

At present, most geothermal wells in Beijing are dominated by combining prospecting with mining; prospecting comes first and mining second. Geological logging is the most direct way to obtain original data during the geothermal prospecting, the quality of which plays a very important role for the quality of well completion. With the Shunhoure-8 geothermal well in the Houshayu area of Shunyi District in Beijing as a study case, this paper discusses the problems concerning rock sample collection, anomalies during drilling, geophysical well logging and well testing.
