Abstract

Abstract

The reservoir of Zhuang 75 block in Wuhaozhuang oilfield is characterized by high formation temperature, serious reservoir heterogeneity, high permeability zone development, and rapid water increase after water injection. For such a high temperature reservoir, the commonly used polymer gel profile control agent has low strength and is easy to dehydrate at high temperature, resulting in poor adaptability. Therefore, a profile control agent of silicone resin with high temperature resistance and high strength is developed. The formulation of profile control agent was optimized in laboratory experiment, and the dissolution time, gel forming time, curing strength, temperature resistance and salt resistance of profile control agent were evaluated. Through the core plugging experiment, the injection ability, plugging ability and water erosion resistance of profile control agent in the core were evaluated. The experimental results show that the silicone resin solution has low viscosity and is easy to be injected into the formation, the temperature resistance is 150℃, the salinity resistance is 200 000 mg / L, and the strength is more than 200 kPa. The silicone resin has a strong sealing performance and good water erosion resistance, after flushed 100 PV by the injected water, the core plugging rate is still above 92%, which meets the requirements of profile control in Zhuang 75 block and can effectively improve the development effect.
