Underground gas storage reservoir simulating experimental device and experimental method

Abstract

The invention discloses an underground gas storage reservoir simulating experimental device and an experimental method, aiming to solve the technical problem that a traditional gas storage reservoir simulating experimental device is incapable of well analyzing running and gas mixing mechanisms of a gas storage reservoir. The underground gas storage reservoir simulating experimental device comprises a gas container, a gas booster pump, a visualized sandstone pore model and a separator, wherein the gas container is connected with the gas booster pump through a pipeline, the visualized sandstone pore model is arranged in a calorstat and is connected with the gas booster pump through a pipeline, a camera is arranged above the visualized sandstone pore model, and the separator is connected with the visualized sandstone pore model through a pipeline. The underground gas storage reservoir simulating experimental device combining data monitoring results of the camera and a computer is capable of observing related percolation phenomena visually, analyzing displacement and mixing mechanisms during all processes effectively and computing fractal dimensions and diffusion coefficients of pore media accurately by simulating gas storage reservoir building, injection production and gas mixing processes.

Description

technical field [0001] The invention belongs to the field of underground gas storage construction, in particular to an underground gas storage simulation experiment device and experimental method Background technique [0002] Natural gas is a country's strategic resource. In order to ensure national energy security, countries around the world have established underground gas storage. At present, the research on the construction, operation mechanism and gas mixing mechanism of gas storage has never stopped in various countries. Especially in the past few years, under the international background of tight oil supply and fluctuating oil prices in the world, the strategy of natural gas in the development of the national economy increasingly prominent status. In the process of production, transportation and use of natural gas, there are fluctuations in gas demand and particularity of storage. With different time periods and seasons, there will be peaks and low peaks of gas consu...
