Title: Development of the Conglomerate Reservoirs by Converting Water Injection Into Steam Injection
Abstract: The Ⅲ conglomerate reservoirs in Kalamayi Oil Field are characterized by high reserve, better physical property and high crude oil viscosity. The avarage oil recovery factor of the reservoirs is only about 23%. They are sensitive to the change of temperature due to the high viscosity. Therefore, the recovery factor of them can be increased by steam injection in the late stage of water injection development. The testing result in Kexia formation, Liuzhong area of the oil field shows that, the oil recovery factor can be increased by thickening flooding network in the areas with high remaining oil saturation, replacing water injection with steam injection in the late stage of water injection dovelopment, and injecting steam intermittently after soaking a cycle.
