摘要
喇萨杏油田进入高含水后期开发以后,部分区块层系注采系统不适应的矛盾越来越严重。针对高含水后期注采系统的主要特点,研究建立了高含水后期注采系统适应性评价方法,对喇萨杏油田高含水后期注采系统的适应性进行了评价,研究确定了注采系统调整的主要方式,对典型区块的调整效果进行了分析。喇萨杏油田高含水后期注采系统调整可以归结为反九点面积井网、四点法面积井网及注采井网不完善等3种类型的调整模式。高含水后期进行注采系统调整可以取得较好的调整效果,提高水驱采收率0.9个百分点左右。成果对油田高含水后期注采系统调整工作具有重要的指导作用。
According to the key features of the injection-production system in the late period of high water cut stage, the evaluation method of its adaptability has been developed and applied in Lasaxing Oilfield. The main adjustment pattern of injection-production system is studied and determined and the adjustment effect of the typical blocks is analyzed. The results have important guidance to injection-production system adjustment in later period of high water cut stage.
