 目前国内外多采用浮力法测定页岩含气量，但这种含气量测试方法的精度不能满足科学研究和生产实践的需求。为了准确测量页岩的含气量，将实验模拟法和解吸法计算的页岩含气量进行对比，结果显示：应用表面张力原理的含气量解吸仪测试的页岩含气量与实验模拟法测试页岩含气量吻合性好，能够对非常规天然气尤其是页岩气进行快速、准确的含气量测试，在科学研究、生产实践及其他相关领域应用前景广阔。

 Buoyancy method is now widely used to determine the content of shale gas domestically and overseas. As the limit of the theories, the accuracy of the gas content test can’t satisfy the need of scientific research and practice of production. In order to calculate the content accurately, this article analyzed the experimental simulation method and desorption method, the result shows that the desorption calculation of shale gas content based on surface tension theory fits well with the shale gas content by the experimental simulation method. The gas content test system can test the unconventional natural gas, especially the shale gas quickly and accurately. It has broad application prospects in scientific research, practice of production and other related fields.
