Problems solved by technology

These methods all have fatal flaws, or they cannot control the porosity and permeability parameters of a single fracture, or they cannot form a three-dimensional fracture network, or they cannot simulate the fracture-matrix interaction
Therefore, the previous methods are difficult to meet the needs of the physical simulation of fractured reservoirs for anisotropic seepage media with quantitative fracture distribution, making it difficult to realize the physical simulation of fractured reservoirs

Embodiment Construction

[0023] The invention proposes a method for making anisotropic seepage medium in fractures. The method uses natural formation rocks as raw materials to process small rock blocks, and then connects these small rock blocks in a predetermined manner to form a large-scale rock mass, so that the small rock blocks The cracks constitute a three-dimensional fracture system in the large rock body, and quantitatively control the distribution of cracks in the large rock body, forming a heterogeneous fracture anisotropic seepage medium with quantitative crack distribution.

[0024] Specifically, the manufacturing method may also include the following steps:

[0025] Calculate the anisotropic permeability of the reservoir: calculate the heterogeneous anisotropic permeability distribution in the reservoir according to the actual reservoir fracture test data;

[0026] Establish a heterogeneous anisotropic fracture model: According to the calculation results of the fracture permeability of the...

Abstract

The invention discloses a preparation method of an anisotropic seepage medium with slits. The method comprises the following steps: natural strata rocks are used as raw material to prepare small rocks, the small rocks are connected in sequence according to a preset mode to form large-scale rock masses so that the gap between the small rocks form a three-dimensional slit system in each large rock mass, the distribution of slits in large rock masses is qualitatively controlled to form the anisotropic seepage medium with heterogeneous slits in qualitative slit distribution. The preparation method of the invention can accurately control and establish slit distribution parameters in the model medium, such as direction and density.

Description

technical field [0001] The present invention relates to a new type of physical experiment method for the study of fractured medium seepage, in particular to a method for making fracture anisotropic seepage medium aimed at the seepage and development process of fractured oil and gas reservoirs in the field of oil and gas field development, and the method is also applicable to other A field of research related to fracture seepage phenomena. Background technique [0002] Fractured media oil and gas reservoirs are common all over the world, accounting for more than half of the proven undeveloped reserves. The basic characteristic of this kind of reservoir is that the movement of fluids such as oil, gas and water in the reservoir is mainly completed through fractures, and the seepage characteristics and seepage process of the fracture system directly determine the development effect of the reservoir. [0003] In order to ensure better results in the development of fractured oil ...
