马36 井区长岩心气(氮) 水交替非混相驱替试验主要用于对比和确定注水、注气(氮) 交替驱替方式下的驱油效率和驱油效果。在完成油藏流体相态拟合之后,利用多组分模型软件^{[1～3 ]} ,对马36 井区的2 组长岩心气水交替驱替试验数据进行了数值模拟研究,取得了良好的拟合效果。数值模拟研究的主要目的是根据试验数据,对相对渗透率曲线和毛管压力曲线^{[4 ]}等参数进行修正,并为油藏数值模拟研究提供符合实际的基本渗流特征数据。

The long core flooding of water alternate gas displacement experimentation on Ma 36 is mainly used to compare and determine the displacement effect between the pattern of water injection and gas injection. Following the fluid phase behavior modeling , the numerical simulation research of the long core flooding of water alternate gas (nitrogen ) displacement experimentation for the Ma 36 reservoir is completed by using a multi-compositional model software. A good matching is reached ; The main purpose of the research is to modify the relative permeabillity curve and the capillary pressure curve ,and provide the practical data of percolation characteristics for the whole reservoir numerical simulation.
