为定量表征泥页岩含气性,用解析法和测井法分别测定鄂尔多斯盆地中南部地区上古生界二叠系山西组泥页岩含气量,并对这2种方法的准确性和实用性做了对比和讨论。结果表明:解析法测定总含气量为1.189cm3/g,测井法得出的总含气量为0.958cm3/g,二者得出的结果基本一致。解析法可以通过分析测试实验直接测量泥页岩含气量,但只能确定取样井段含气量,而且测量结果易受取心方式及时间长短的影响。测井法可以确定全井段含气量,但应根据大量分析实验数据,选取合适的参数,才能建立可靠的数据计算模型。这2种方法对确定泥页岩含气量都有各自的优势,互为补充,二者结合可以为确定泥页岩含气量及有利区优选提供可靠依据。

The shale gas content plays an important role in quantitatively evaluating gas bearing potential.The desorption method and log interpretation method were used in this study to respectively determine shale gas content of Shanxi Formation in central and southern Ordos Basin.Results show that shale gas content is 1.189cm3/g by desorption method and 0.958cm3/g by log interpretation method.Results of the two methods are close.In addition,the accuracy and applicability of the desorption method and log interpretation method were compared and discussed.Gas content of shale can be directly measured by laboratory test in desorption method,but the result is easily influenced by coring methods and exposing time of cores.Consequently,effective coring is the key for exactly measuring gas content of shale.Gas content of shale for the whole well can be calculated by the log interpretation method,but that was based on abundant laboratory data and selection of appropriate parameters.Both methods have their own advantages and can complement each other.Combination of the two methods can provide an important basis for calculating shale gas content and searching for favorable exploration areas.
