Rock samples with permeability less than 1 × 10~-3 μ m~ 2 are used to conduct an experimental study on the effect of start-up pressure gradient of in-place oil percolating through rocks. 利用渗透率小于1×10-3μm2的油层岩样,试验研究了地层油通过岩石渗流启动压力梯度的影响。
An Analysis of Difference of In-Place Oil and Gas Property 地层油气性质的差异原因分析
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;
