Title: Study on the Preferential Seepage Channels and Development Strategy in QHD32-6 Oilfield
Abstract: In allusion to the production situation of rapid increase of water cut and a low oil recovery level in QHD32-6 Oilfield,a comprehensive study showed that the injection performance of injection well and the production performance in the area were fully used to judge the preferential seepage channels.It was considered that viscosity ratio between oil and water,distance between wells,forced injection and production,long time and large-scale water flooding were the important factors controlling the preferential seepage channels of offshore heavy oilfields.On the basis stated above,some measures to improve the waterflooding effect of exploitation are proposed including mechanic water checking,water shutoff and profile control,zoning water injection and proration,better oil-stimulation and water-controlling effects are obtained.The method provides reference to other offshore heavy reservoir development by water-flooding.
