AS/P交替注入矿场试验效果及认识
EFFECTS AND COGNITION ON THE FIELD TEST OF AS/P ALTERNATING INJECTION
摘要
Abstract
Aiming at the problems of the serious decrease of injection-production capacity and high-cost chemicals etc. exposed in the industrial tests of ASP flooding in Daqing Oilfield, the injection patterns of ASP system are optimized by the methods of physical and numerical simulations. The study show that the chemicals dosage of AS/P alternating injection can be cut down by 22. 06% comparing with ASP overall injection in the same conditions of production effects and furthermore the recovery factor can be enhanced 2. 7% in the same chemicals dosage. AS/P alternating injection field test show that the maximum water cut of those central wells are decreased by 16. 7% , the oil recovery factor is enhanced by 11. 85%. And moreover the production cost is greatly reduced, thus the achievements above have provided an evidence for the development effects of the further improvement of ASP flooding.关键词
