Abstract:
Based on the basic characteristics of multi-cycle, large flow, strong injection and strong production of gas storage, this paper focuses on the sealing mechanism of gas storage trap for reconstruction of depleted gas reservoir by means of laboratory experiments and numerical simulation techniques, and applies four key characteristic technologies of gas storage construction, including trap sealing evaluation, storage capacity parameter evaluation, injection and production capacity evaluation and gas storage operating parameter evaluation to improve the science and reliability of geological scheme design of underground gas storage for depleted gas reservoirs and optimize the operating parameters of gas storage.
