Abstract

The invention provides a simulation system and simulation method of hydrocarbon generation, adsorption and desorption of shale. The simulation system comprises a shale gas self-generation device, a shale gas self-absorption device and a shale gas yield counting device which are connected in sequence. The shale gas self-generation device is used for simulating the hydrocarbon generating process of shale, the shale gas self-absorption device is used for simulating the adsorption and desorption processes of hydrocarbon gas, and the shale gas yield counting device is used for counting simulation parameters of the hydrocarbon gas released by desorption of the shale gas self-absorption device. The simulation system further comprises a control device connected with the shale gas self-generation device, the shale gas self-absorption device and the shale gas yield counting device. The control device is used for controlling the work pressure and temperature of the shale gas self-generation device to simulate the hydrocarbon generating process under different temperatures and pressures, controlling the work pressure and temperature of the shale gas self-absorption device to simulate the adsorption and desorption processes of the hydrocarbon gas under different temperatures and pressures, and controlling the shale gas yield counting device to count the simulation parameters of the hydrocarbon gas released by the shale gas self-absorption device. The simulation system can effectively, quickly and conveniently guide shale gas exploration and development practice.

Description

technical field [0001] The invention relates to the technical field of gas volume measurement, in particular to a shale hydrocarbon generation, adsorption and desorption simulation system and simulation method. Background technique [0002] Shale gas is a kind of natural gas with non-structural control and large-scale accumulation. The generation, accumulation, decompression and desorption production of shale gas have different accumulation processes and exploration and development processes from conventional natural gas. Shale gas is divided into adsorbed gas and free gas. Shale gas has typical self-generation and self-storage characteristics. The generation of shale gas mainly comes from the diffusion and desorption of gas from the shale matrix. With the prospect of commercialization, the data of hydrocarbon generation and adsorption accumulation of shale gas in this area should be simulated first. [0003] However, at present, there is no shale gas hydrocarbon generation...
