基于流线数值模拟研究高含水后期油田的剩余油分布
Application of streamline numerical simulation method to study of remaining oil distribution in high water-cut stage oilfield
摘要
Abstract
According to the geologic and developmental features of the Ng6 3+4 of Neogene Guantao Formation in western No.7 district in Gudong Oilfield,one experimental zone in Ng63+4 unit is used to study the distribution of remaining oil in high water cut stage oilfield.The history matching of the reserves,pressure,moisture content and single drilling well water cut in the experimental zone produces a fine 3D geological model and parameters mode of less than 5% errors for 85% single-drilling wells. With the help of streamline numerical simulation technique, it obtains the characteristics of fluid migration under the condition of dense well pattern in high water-cut stage and divides remaining oil distribution patterns.It shows that large channel and high permeability zone are formed in the underground reservoir and the fluid migrates mostly along the high permeability zone. At the same time,oil displacement efficiency decreases obviously.The remaining oil distribution is controlled by sedimentary facies,sedimentary rhythm intraformational heterogeneity and drilling well network,the remaining oil occurs in the top of micro-structures,low permeable section in the plane and mainly concentrates on the top of the positive rhythm in the thick oil layer.关键词
