稠油储集层地化分析与评价

Geochemical Analysis And Evaluation For The High Viscosity Oil Reservoir

根据目前胜利油田稠油分布较广的情况,从稠油地化特征入手,根据地化参数,计算含油饱和度,并应用Pg与OPI值判别稠油储层性质及含油级别,经试油对比该方法效果较好,提高了地化解释的符合率。

According to the large extension of the high viscosity oil zones in Shengli Oilfield,the paper presents a geochemical method for oil saturation calculation with high viscosity reservoir property and the oil-bearing grade with the data of P\-g and OPI.These methods has been verified to be very good compared with the well-testing result and they can increase the interpretation coincidence rate.
