摘　　要：目的研究分析影响B-A两油田储层物性差异的主要因素。方法通过岩心分析、测井资料综合解释和试井分析等手段研究B-A两油田白垩系的储层物性分布规律;通过岩性、成岩作用、沉积环境和构造运动等方面分析物性差异的影响因素。结果B油田白垩系具有高孔高渗的储层物性特征,而A油田为中孔低渗的特征。B油田为一套辫状河道沉积,沉积物胶结疏松且粗组分含量高而黏土矿物和碳酸盐胶结物含量低。A油田为三角洲沉积,沉积物细且碳酸盐胶结作用强烈,碳酸盐和黏土矿物含量高。结论沉积环境和成岩作用是造成两个油田白垩系储层物性差异的主导因素。Aim To study the reservoir physical property distribution characteristic in B and A oil fields and its influence factors. Methods Physical character has been studied by means of core analysis, well log interpretation and well test data. And their influence factors have been analyzed from lithology, diagenesis, sedimentary condition, structure movement and so on. Results High porosity and high permeability are the characteristic of the reservoir in B oil field, and A oil field is middle porosity and low permeability. B oil field belongs to braided - fiver sediment with loose bonding, high coarse content, low clay mineral content and low carbonate cement content. A oil field belongs to delta sediment with fine sediment, strong cementation, high carbonate cement content and high clay mineral content. Conclusion The sedimentary condition and diagenesis are the two main factors that influence the difference of physical property between the two oil fields.
