摘要

应用电阻率测井原理，建立了一套大型露头模型平面流场测量方法。在此基础上利用特低渗透天然砂岩露头制作大型露头模型进行流场分布规律研究。研究表明，对于平行岩样具有非线性渗流特征的大型露头模型，其井网单元内平面流场特征为注入流体沿主流线方向快速突进，但波及范围较小，且存在不流动区，驱替效果较差。分析了不同驱替倍数下流场的变化规律，对比研究了不同因素对流场以及有效驱动的影响。大型露头模型能直观地反映流场动态的变化过程和驱替效果，能够更好地模拟实际油藏渗流规律。

Abstract

Using the resistivity logging principles

a method for measuring the flow field of large-scale outcrop model is established. On this basis

flow field distribution regularity is studied by the model making by ultra-low permeability sandstone outcrops. The research shows that: for the large-scale outcrop model with nonlinear seepage characteristic

the flow field characteristic of the well pattern element is that the injection fluid advances rapidly along the main stream line but impact area is small; and non-flowing area exists

where displacement efficiency is low. The changing laws of flow field at different multiples are analyzed. The influences of different factors on flow field and displacement efficiency are studied. The large-scale outcrop model can reflect the dynamic process of flow field and displacement efficiency

and can simulate the seepage law of the real reservoir better.
