摘要： 西峰油田庄 19 井区长 82 储集层属低渗透储集层。采用真实砂岩微观模型水驱油实验(包括单模型和组合模型)对研究区的水驱油机理及影响水驱油效率的因素等进行了较为系统的分析研究,逼真、直观地模拟了水驱油过程中流体的渗流特征及残余油分布规律,为该井区及同类型油藏制定合理的注水开发方案提供了一定的依据。

Abstract: Chang-82 reservoir of Well block Zhuang-19 in Xifeng oilfield is of very low permeability and poor petrophysical properties, belonging to a low-permeability reservoir.The water-oil displacement mechanism and efficiency-affected factors in the studied area are analyzed systematically using real sandstone micro-model for water-oil displacement experiment (including single model and combination model), offering the realistic and visual percolation characteristics of fluids and remaining oil distribution in the process of water-oil displacement.This study can be as a guide for water flood scheme design of such a well block and other similar reservoirs.

Key words: micro pore structure, low permeability, micro fissure, oil-water displacement mechanism, oil-displacement efficiency, remaining oil
