川南页岩气藏具有分布广、易发现、丰度低、难动用的特点。针对页岩气藏的以上特点,利用现场录井资料,采用微钻时、岩石可钻性、气测、岩石热解、岩屑显微图像、随钻伽马等配套综合录井技术对页岩气储集层进行综合评价,在快速发现和解释钻井中页岩气显示方面取得了较好的效果,为安全钻井和试油层段的选择提供了依据。
The South Sichuan shale gas reservoir has the characteristics of wide distribution, easy to find, low abundance and difficult to use. According to the above characteristics of shale gas reservoirs, we use the logging data of the site, the micro-drilling, rock drillability, gas measurement, pyrolysis of rock, microsection of debris, Gamma logging, Comprehensive evaluation of rock gas reservoirs has yielded good results in the quick detection and interpretation of shale gas in drilling and provides the basis for the selection of safe drilling and test reservoirs.
