摘要
通过观察岩心、裂缝监测并运用主曲率法裂缝定量计算等手段 ,对文东油田A区盐间低渗透油藏的裂缝性质、类型和分布规律进行了综合研究。发现A区沙三段中亚段储集层发育大量天然裂缝 ,具有构造垂向上分带性及平面上分片性等特征。根据裂缝分布规律 ,优化了A区注采井网 。
Features, type and distribution rule of the fractures in low?permeability oil reservoir of A area in Wendong oilfield are studied synthetically through observing cores, monitoring fractures and quantitative calculating fractures using principal curvature method. It is found that a lot of natural fractures developed in the reservoir of middle Es 3 in A area with the features of vertical zoning and plane parting on structure. The flooding pattern of A area is optimized according to the distribution rule of the fractures. Productivity and waterflooded sweep efficiency of this oil reservoir raised effectively.
