摘要

致密糯米团储层结构复杂,矿产类型多,多为非达西定律流动 基于糯米团水淹渗流的有限元 COMSOL 模拟,本章主要探讨了几个相关因素对位移采收率的影响。随着润湿角的增大,润湿性使得胶凝岩中固体和流体的多孔状态稳定,水很容易将油挤出,从而导致水淹采收率的提高 注水速率越高,短时间内的截水量越大,使得油水两相位移加速,位移采收率越高 随着砾石直径的增大、小砾石颗粒对水驱前端影响小,没有明显的主导通道,采收效果差。

Study on the Simulation Law of Two-Phase Seepage in Gravel Based on Phase Field Simulation

Tight glutenite reservoir structure is complex, mineral types are multi-seepage, and most of them are non-Darcy’s law flows Based on the finite element COMSOL simulation of seepage flow in glutenite water flooding, this chapter mainly explores the influence of several related factors on displacement recovery. With the increase of wetting angle, the wettability makes the porous state of solids and fluids in glutenite stable, so that water can easily push oil out, which leads to the increase of water flooding recovery The higher the injection rate, the higher the water cut in a short time, which makes the oil-water two-phase displacement accelerate and the higher the displacement recovery With the increase of gravel diameter, the oil saturation decreases less and more crude oil is bound by the pore structure surrounded by large particles, which is not conducive to displacement Small gravel particles have little influence on the front of water drive, and there is no obvious dominant channel, which leads to the recovery effect.
