New processes for well completion, cementing, and development in super heavy oil reservoirs

Along with the oilield development, the development of super heavy oil reservoirs has been an important measure to enhance oil recovery and stabilize production. Since there are no mature development modes and systematic techniques matching with the development of super heavy oil in China, according to the characteristics of super heavy oil in Tuo 826 block, the sand control completion technique by using precision screen in horizontal wells, the cementing technique on the top of screen pipes, the sand control technique based on gravel packing and the technique of injection-production integration are applied, on the basis of casing perforating cementing of horizontal wells. As a result, the pollution of slurry to the oil zone is prevented, the working life of oil wells is prolonged, the thermal loss of thermal recovery is reduced, and the oil recovery is enhanced.
