[0002] Shale gas is a natural gas resource that is contained in shale reservoirs and can be mined. With the rapid development of shale gas exploration and development in my country, the evaluation of the gas content of shale reservoirs is particularly important. The total content of shale lost gas in shale reservoirs is one of the parameters for evaluating the gas content of shale reservoirs. Therefore, a method for determining the total content of shale lost gas is urgently needed. When shale gas is mined, the core containing shale gas needs to be extracted from the shale reservoir to the ground and then loaded into a desorption cylinder.

[0003] When the existing shale gas formation sample storage equipment is used, the storage box cannot be enhanced to seal the shale gas formation samples, resulting in external gas entering the storage box, thereby reducing the accuracy of the detection. At the same time, when the shale gas samples are placed inside the storage tube, the sealing method is too simple and a good sealing effect cannot be achieved for the storage tube.
