通过实验研究了润湿性对采收率及相对渗透率的影响,还研究了利用原油老化控制岩石润湿性的方法。
The effect of wettability on recovery and relative permeability by waterflood test and the method of controlling rock wettability by aging crude oil are studied in this paper.
岩芯的X射线光电子能谱分析显示,纳米聚硅和表面活性剂能吸附在岩石表面上,改变岩石表面的润湿性,提高水相相对渗透率。
According to the result of XPS, the nanometer polysilicon and the surfactant can adsorb on the rock surface, change its wettability, and enhance the water relative permeability.
地层岩石相对渗透率的变化会影响地层中油水的流动,因此对试井曲线形态的影响也很大。
It is well known that the change of the rock relative permeability will effect on oil and water flow in the formation, therefore, the change will greatly effect on the shape of well test curve.
