Problems solved by technology

[0009] CN203412578U discloses a heterogeneous physical model between layers of oil layers, which mainly solves the problem that the existing rock core resources in the prior art cannot meet the characteristics of a class of oil layers after polymer flooding
[0011] However, there are still many things to be improved in the above-mentioned prior art. For example, in CN103247215A, although the multi-layer co-production experiment is used to simulate the oil layer more realistically, the simulation degree of the real situation of the oil layer is still not high enough. The effect of pores, ignoring the effect of pores or cracks in the oil layer

Abstract

The invention discloses an oil layer simulation processing method. A system used in the method comprises an injection device, multiple planar model layers, and a measurement device. The injection device is connected with all the planar model layers, and all the planar model layers are connected with the measurement device. The injection device is used for injecting displacing fluid into the planar model layers. The planar model layers are packaged with natural low-permeability sandstone slabs of different permeability, and are used for simulating different sub layers of a multi-layer oil reservoir. The injection device includes a well penetrating the planar model layers, and the wall of the well is provided with one or more perforations horizontally extending into the planar model layers.

Description

technical field [0001] The invention relates to a plane simulation experiment method in the oil reservoir exploitation industry, in particular to an oil layer simulation processing method closer to real oil reservoir conditions. Background technique [0002] One-dimensional core and flat plate models are mainly used in experimental research for indoor physical simulation of oilfield field development and production. For many low-permeability reservoirs, one of the notable features is strong heterogeneity, with large differences in reservoir physical properties in different parts, and different control effects on fluid flow. Due to the existence of heterogeneity, the production degree of multi-layer reservoirs is quite different, the interference between layers is serious, and the water flooding effect of each layer is quite different. [0003] In order to study the difference in water flooding effect of each layer, fluid flow characteristics and distribution rules in this k...
