Study on Heterogeneity of Putaohua Reservoir in Block Zhao 35 of Songfangtun in Daqing Oilfield
摘要
Abstract
Based on the theory of reservoir heterogeneity, this study researched the characteristics of intra-layer heterogeneity, inter-layer heterogeneity, plane heterogeneity and micro-heterogeneity, and analyzed the controlling factors. The results showed that the intra-layer heterogeneities were controlled by the sedimentary structures, the permeability rhythms and the distribution of interbed. The distribution characteristics of physical property and interlayer were analyzed and the heterogeneities changed from weak to strong then to weak from bottom to top within Putaohua reservoir. The plane heterogeneities were mainly affected by the distribution of sandstones and sedimentary micro-facies. Along the extending direction of underwater distributary channel, the heterogeneity was good. The primary intergranular pore, secondary intergranular dissolved pore and intragranu-lar dissolved pore developed well in the study area, and the micro-pore structures were fine. The distribution of remaining oil was influenced by the heterogeneity in different aspects. The sedimentary facies types and diagene-sis were considered as the main controlling factors of reservoir heterogeneity. Finally, this study predicted the developing area and distribution range of favorable reservoir for the main productive layers of Putaohua reservoir, and the result provided a certain foundation for the future exploration in the study area.关键词
