海上多层合采油藏原油性质评价方法——以PL油田M区为例

Crude oil properties evaluation method of offshore multilayer commingled oil reservoirs——a case study of PL oilfield M area

以PL油田M区为例,将"归一化"思想引入到地面原油性质评价的同时,采用统计回归分析方法评价地层原油性质,二者有机结合最终确定了评价区原油性质。理论计算值与实测值的对比分析证实,本文所提出的原油性质评价方法体系具有较强的适用性。

By taking M area of PL oilfield as an example,for the introduction of the 'normalization' into the ground crude oil properties evaluation,the statistical regression analysis method is adopted to evaluate the nature of in-place crude oil.With the combination of these two methods,the crude oil properties in the area have been finally determined.Through comparison between the theoretical and measured values of the analysis,the methodology of crude oil properties proposed in this article is of strong applicability.
