摘要
建立了深部调驱平面均质纵向非均质以及平面非均质纵向非均质三维物理模型。在该模型上布置了压力传感器和饱和度测量器,测量了不同模型不同井距下的注入压力、出液量、出油量和各点含油饱和度,计算了水驱采收率、注调驱剂后采收率和最终采收率,绘制了驱油效果图和含油饱和度场图,得出了在经济条件允许的情况下,井距越小、水驱效果越好、注入调驱剂后效果越好、总采收率越大的结论,从而为油田在深部调驱情况下合理井距的选择提供理论依据。
Some 3-D physical modelings of plane homogeneous vertical heterogeneity and plane heterogeneity vertical heterogeneity for deep profile control were established. Pressure sensors and saturation measuring apparatuses are arranged in these models,injection pressure,fluid output,oil output and oil saturation of each point were measured,the recovery after water flooding,the recovery after injecting profile control agent and the ultimate recovery,manufacture the oil displacement effect diagram and the oil saturation distribution diagram was calculated. In the case of economic conditions permit the conclusion was obtained that the better effect of water flooding,the better effect after injecting profile control agent,the bigger of total recovery with the well spacing is smaller,to oil field in deep profile control and flooding reasonable well spacing selection provides a theoretical basis. Thereby the theoretical basis for oil field in selecting the reasonable well spacing when implementing deep profile control is provided.
