摘要(Abstract)：

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.
