Fine reservoir numerical simulation has been performed for Hu-12 block reservoir in this paper, and a method to determine the remaining oil in-place is presented based on economical residual oil saturation from water-oil relative permeability relations at 98% water-cut underground. 本文以精细油藏数值模拟的计算结果为基础,通过油水相对渗透率关系反求出含水率为98%时的残余油饱和度,建立了计算剩余可采储量分布的方法;
On the consideration that the solid particle in wastewater invades into formation and plugs the pores so that reduces the in-place permeability, a mathematical model that is summarized as problem 1 and problem 2 has been developed. 考虑污水中固体颗粒侵入地层,堵塞孔隙降低地层渗透性,对其建立数学模型,将模型归结为问题1和问题2。
