ZT2油藏开发数值模拟研究

Research on numerical simulation of ZT2 oil reservoir development

首先对ZT2油藏流体高压PVT实验数据进行拟合计算,确定了适合描述该油藏流体相态行为的流体组分特征参数;利用地质资料及其研究成果所得到的地层物性参数,并且通过油藏精细描述提供的物性数据,建立了相应的三维地质模型;在完成了油藏地质储量拟合以后,为了研究ZT2油藏未来的开发动态,从井数、采油气速度、边水侵入强度、注采比等多个方面对该油藏的开发指标进行了数值模拟对比研究,其研究结果为该油藏的生产开发提供了可靠的依据。

The PVT experiment data of ZT2 oil reservoir with high fluid pressure are matched and the fluid component characteristic parameters, which can describe the phase behavior of condensate gas reservoir, are determined in this paper. According to the stratigraphic petrophysical parameters and the result of oil reservoir description, the three-dimensional geological model is built. After the match of oil reservoir geologic reserves, in order to study the performance of development, the numerical simulation research of the oil reservoir is completed from the aspects of well number, oil and gas production rate, intensity of fringe water invasion and injection-production ratio. The study results provide a reliable foundation for the oil reservoir development.
