摘要(Abstract)：

海上普通稠油油藏具有储层厚度大、非均质性强和岩石胶结强度低等特点,水驱开发效果较差。为了加快油田开发速度和提高原油采收率,以物理化学、高分子材料学和油藏工程为理论指导,以化学分析、仪器检测和物理模拟为技术手段,以渤海某油田储层地质特征和流体为研究对象,开展了Cr~(3+)聚合物凝胶储层适应性及作用机理研究。结果表明:随储层平均渗透率和渗透率变异系数增加,聚合物凝胶调驱增油效果变好;随聚合物凝胶注入时机提前,聚合物凝胶调驱效果变好;随原油黏度增加,聚合物凝胶调驱效果变差。
Offshore common heavy oil reservoirs are characterized by big thickness,strong heterogeneity,low rock cementation strength and so on,so the water flooding effects are rather poorer.In order to speed up the development and enhance the oil recovery,guided by the following theories i.e.physicochemistry,high-molecule materials and oil reservoir engineering,taking chemical analyses,instrument detection and physical simulation as the technical methods,regarding the geological characteristics and fluids as the studying objects for the reservoirs in an oilfield of Bohai Bay,the reservoir adaptability and its acting mechanism of Cr~(3+) polymer gel are researched.The results show that with the increase of the average permeability and permeability variation coefficients of the reservoirs,the oil incremental effects of the profile-controlling and flooding become much better;with ahead of the time of the injection opportunity,so are the above effects;on the contrary,with the rise of the oil viscosity,the effects become rather poorer.
