摘要

With the increase of natural gas production in China and its increasingly common in industry and daily life, Gas storage plays an increasingly important role in regulating natural gas seasonal peak and coordinating supply and demand, Oil reservoir type gas storage has two functions of storing natural gas and enhancing oil recovery.In the operation of oil reservoir type gas storage, the method of gas injection and oil recovery is the key factor affecting the economic effect of gas storage.Take XX reservoir gas storage as an example, the gas injection mode and oil recovery mode of gas storage are numerically simulated, the influence of injection-production mode on storage capacity of reservoir gas storage is discussed, the results show that the method of injection first and circulation injection production, mid-term pressure boost drainage can form larger storage space and improve oil recovery.The research results have a certain guiding significance for the design of gas storage injection-production operation scheme.
