仿真模型模拟储气库建库与气库运行实验研究

The Experimental Research of Gas Storage Building and Operating with Simulation Model

为了明确真实地层条件下枯竭油藏储气库中气、水、油三相运行机理和气库运行效率影响因素。利用渗流所自主研发的透明二维玻璃模型,模拟高温高压条件下枯竭油藏地下储气库的多周期注采,定性研究了气、水、油三相的渗流特征。实验结果表明:储层物性影响气库库容,储层非均质性越严重,库容和运行效率越低。合理提高注采压力能够增加气库库容和运行效率。

In order to make clearly of the operation mechanism of gas-water-oil and the Factors affecting effi- ciency of dry gas storage reservoir. This research simulates the multiple injection-production cycle under high pres- sure and temperature using two-dimensional transparent glass model develop independent by institute of porous flow. In addition, the experiment also discusses the seepage characteristics of gas, water and oil. The result shows the physical properties of the reservoir affect the capacity of gas storage. The more severe of the heterogeneity, the lower capacity and efficiency of the gas storage. What＇ s more, improve injection-production pressure reasonably can enhance the capacity and efficiency of underground gas storage.
