摘要
为探索断块油藏人工仿边水驱技术的可行性,采用先进的三维物理模拟实验设备,在相似准则基础上针对实际油藏进行了三维物理模拟实验。模型饱和度场分布与流体的渗流特征研究表明,边水模型的无水期采出程度明显高于点状模型,点状模型在改为边水驱后采出程度提高了16.6%。人工仿边水驱可扩大水驱波及体积,提高驱油效率,改善水驱开发效果。
In order to explore the feasibility of the simulated edge-water driving technique for fault-block oil reservoir, by means of the advanced 3 D physical simulating experimental equipment, on the basis of the similarity criterion, the experiment and test is conducted for the actual oil reservoir. The researches on the saturation field distribution of the model and seepage characteristics of the fluids show that the anhydrous recovery degree of the edge water model is significantly higher than that of the point model, the degree of the latter is up to 16.6% after inverted into the edge water drive. The simulated drive can enlarge the swept volume of the water flooding, enhance the swept efficiency and finally improve the development effects.
