摘　　要：大庆肇州油田州57区块位于松辽盆地北部中央坳陷区三肇凹陷内,为多条断层切割的非均质砂岩油藏。主要含油层位是葡萄花油层,沉积时期处于松辽盆地北部大型三角洲沉积体系的前缘相带到湖相的过渡带上。截止2010年12月,采油井综合含水48.4%,有23口井含水已达90%以上,占采油井总数的23.4%。分析认为,储层的高渗条带是影响开发效果的主要因素。研究了高深条带的形成机理,并从岩心及测井资料入手,结合沉积相及生产动态对高渗条带进行了识别及分布预测,为高渗条带的治理及注采井网的调整奠定了基础。Zhou57 area in Zhaozhou Oilfield locates in Sanzhao depression of central depression belt in northern Songliao Basin,developing sandstone reservoir truncated by large numbers of faults.The main layer is Putaohua Formation,deposited in the transition zone from a large delta front to lake in northern Songliao Basin.By Dec.2010,the water cut in study area reaches 48.4%,of which 23 wells exceed 90%,with a proportion of 23.4%.Research suggests that the existence of high-permeability belt is the main reason of influencing the reservoir development.Genetic mechanism of high-permeability belt is studied,made out the belt and predicted its distribution combining the core analysis,well data,faces results and production performance,which provides a guide for the adjustment of oilfield exploration.
