【 摘 要 】

Sashing oilfield has entered the high water cut development stage, and the oil recovery has been obviously improved under the guidance of constantly improving subdivision water injection technology. However, some layers cannot be used effectively under conventional water injection conditions due to factors such as the development condition of oil layers. The stratified indicator curve can clarify the starting pressure of each water injection layer and the variation law of water absorption capacity of different layer under the same pressure conditions, which can effectively guide the injection test adjustment or pressurized water injection of multi layers, and shallow profile control or plugging with fine selection of strong water absorption layer. The stratified indicator curve has a good site application effect, and is of great guiding significance for optimizing the adjustment scheme of injection wells and improving the development degree of oil layers.
