萨尔图北一、二排西上返区块采出程度分析

ANALYSIS OF THE RECOVERY DEGREE OF THE UPWARDS BLOCK OF THE WESTREN BEIYIER LINE IN THE SAERTU OILFIELD

大庆油田萨尔图中部开发区北一、二排西部区块主力油层葡萄花油层Ⅰ组结束聚合物驱油后即将上返到萨尔图油层萨Ⅱ10-萨Ⅲ10单元层注聚合物,这个区块是大庆油田第一个二类油层聚合物工业驱区块,其注聚合物前的采出程度的准确标定关系到大庆油田二类油层聚合物工业驱的效果评价和进一步推广应用。通过对该区块的动态、静态资料的四种不同计算采出程度方法优缺点加以分析对比,认为“静态资料法”比较合理,并将该方法计算结果标定为区块注聚合物前采出程度。

After polymer - flooding the chief reservoir in the Western Beiyier Line in the central Saertu Oilfied, polymer-flooding will be done upwards into Saertu reservoir SⅡ10-SⅢ10 witch is the second type oil layers where the polymer-flooding is first performed. For holding the accurate recovery degree prior to polymer- flooding concerns the result evaluation and application on polymer-flooding in the second type oil layers, on the basis of comparing the advantages and disadvantages by computing the static and performance data in 4 calculating methods, it was concluded that the static calculating method is more rational. We had taken the results calculated with static method as the recovery degree ahead of polymer- flooding.
