摘要:

针对渤海稠油油田原油黏度覆盖范围广、实施聚合物驱时机早晚不一的问题,需对预测水驱产油量的水驱特
征曲线方法进行适应性分析,以便筛选合适的增油量评价方法。根据渤海海域某稠油油田实际油藏数据,建立典型模
型,考虑不同聚合物驱时机和不同原油黏度情况下,分别用甲型、乙型、丙型、丁型水驱特征曲线预测不同含水阶段下
水驱产油量,从而得到相应的聚驱增油量,与数模计算结果对比,计算其平均误差和标准差,从而筛选出合适的增油量
评价方法。根据适应性分析结果,对渤海某聚合物驱试验区进行增油量分析,与数值模拟跟踪评价结果对比其结果误
差较小,准确性高。为准确计算渤海油田聚合物驱增油量提供了借鉴和指导。

Abstract:

Because of different oil viscosity and polymer injection time,it is necessary to analyze the adaptability of the
water flooding characteristic curves,which are used to predict oil production of water flooding,so as to select the suitable
incremental oil production evaluation method. Based on the actual reservoir data,typical models were built. Taking into
consideration different polymer injection time and oil viscosity,oil production of water flooding was predicted using different
water drive characteristic curves,thus the incremental oil production was determined. According to the results from numerical
simulation,average error and standard deviation were computed,and the appropriate evaluation method was selected. Based
on adaptability analysis results,incremental oil production of the polymer flooding trail in Bohai oilfield was calculated,and
the error was small compared with the results from reservoir simulation. This provides reference and guidance to accurate
calculation of incremental oil production for polymer flooding in Bohai Oilfield.
