The invention discloses a simple experiment device and method for shale gas adsorption and desorption. The simple experiment device comprises a gas tank, a shale sample tank, a constant temperature water tank and a gas weighing device. The gas tank is connected to the shale sample tank through a pipeline and is installed on a supporting table, and the shale sample tank is fixedly connected to a support, can be wholly placed in the constant temperature water tank and is connected to the gas weighing device through a vacuum pump. Shale gas adsorption and desorption experiments are realized by means of the simple experiment device formed by the gas tank, the shale sample tank and the vacuum pump. The operation method is easy and convenient, the experiment device is low in manufacturing cost and test cost, convenient to maintain and low in maintaining cost, the experiment method is simple, and data are accurate and reliable; the simple experiment device and method have the advantages that the structure is simple, and the data are reliable.
Description
technical field [0001] The invention belongs to the field of shale gas adsorption and desorption experimental devices, in particular to a simple experimental device for shale gas adsorption and desorption, and also relates to an experimental method for the simple experimental device for shale gas adsorption and desorption. Background technique [0002] my country's shale gas reserves rank among the highest in the world. With the great success of the United States in shale gas mining, my country attaches great importance to shale gas mining. Most of the shale gas is stored in the pores and fractures of shale in the state of adsorption, and a small part exists in the shale in a free state. The study of adsorption and desorption of shale is of great significance to improve the gas production of shale gas. At present, there are many experimental instruments for studying the adsorption and desorption of shale gas, but these instruments are quite expensive, and generally only avai...
