Light Hydrocarbon Analysis and Evaluation Technique of Reservoir Produced Fluid Property

轻烃分析技术是近几年发展起来的辅助性储层评价技术,该技术通过对储层样品进行90℃温度条件下的色谱分析得到C9以前的饱和烃及芳烃。根据有机化学的基础理论———在相同的物理条件下同碳数的饱和烃及芳烃在水中的溶解性有明显区别的特点,初步建立了松辽盆地中浅层油水层的识别及评价技术。

Light hydrocarbon analysis is a new technique for reservoir evaluation,which develops in recent years.It is used to obtain saturated hydrocarbon and aromatic hydrocarbon before C9 through chromatographic analysis on reservoir samples with a temperature of 90℃.Based on theory of organic chemistry-in same physical conditions,saturated hydrocarbon and aromatic hydrocarbon with same carbon number have apparent different dissolving characteristics in water,this paper establishes identification and evaluation technique for middle-shallow oil and water layers in Songliao Basin.
