Abstract

The invention discloses a commingling production physical simulation system and method of a permeability oil reservoir. The system comprises an injection device, a plurality of planar models and a measurement device, wherein the injection device is connected with each planar model, each planar model is connected with the measurement device, and the injection device is used for injecting a displacement fluid into the planar models; the planar models are formed by packaging natural low-permeability sandstone flat plates with different permeability and used for simulating different small layers of the multi-layer oil reservoir; a pressure measurement point is arranged on the front surface of each planar model and used for measuring the pressure field of a pressure measurement point of each planar model, and an electrode measurement point is arranged on the back surface of each planar model and used for measuring the flow field and the saturation field of each planar model; and the measurement device is used for collecting the pressure field, the flow field and the saturation field of each planar model.

Description

technical field [0001] The invention relates to a plane simulation experiment of geological development in the petroleum industry, in particular to a physical simulation system and method for multi-layer co-production of seepage oil reservoirs. Background technique [0002] At present, the experimental research for indoor physical simulation of oil field development and production mainly uses one-dimensional core and flat plate models. For 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. In order to study the difference in water flooding effect of each layer, fluid flow characteristics and distribution rules in ...
