摘要
通过对原油开采过程中影响采收率的因素进行分析 ,结合影响采收率的机理研究 ,采用加权因子的方法计算采收率 ,并运用灰色关联分析法确定了油田开发中影响采收率各因素的权重 ,建立了一种对聚合物驱油区块整体评价的模糊综合评判方法并应用于中原油田聚合物驱油区的目的区块 ,明确了实施提高采收率技术的主要方向 ,给出了筛选区块的现场试验效果。
Based on the analysis of the factors related to the oil recovery and the mechanisms related to the flooding efficiency, weight definition is made to confirm the factors affecting the oil recovery with the relationship analysis,a method is set up in the comprehensive evaluation to the polymer flooding reservoir analysis and the evaluation of blocks in the Zhongyuan oil field is completed.The main methods of EOR are put forward and the pilot test results of the screened blocks are given.
