摘要
薄差油层是厚度小于1 m的表内薄层以及表外油层,储层渗透率差,因此影响因素与主力油层不同。应用聚类分析方法对油水井进行了分类,通过单因素分析,评价了7个对薄差油层聚驱开发效果起主要影响的指标,利用主成分分析和统计学分析,建立了一套新的薄差油层聚合物驱油效果评价方法。
Thin and poor oil layer is thin layers with effective thickness less than 1 m,or untabulated reservoirs, and it has low permeability. So its influence factors are different from the main layers. In this paper, the oil and water wells were classified by applying the clustering method. By single factor analysis, seven main indexes affecting the development effect of polymer flooding in the thin and poor layers were evaluated. Using principal component analysis and statistical analysis, a new evaluation method for polymer flooding effect in thin and poor oil layers was established.
