Description
Technical Field
The invention relates to the fields of petroleum, mineral products and geology, and provides an experimental method for providing true triaxial confining pressure for a large-scale true core flat plate model.
Background
The exploitation and utilization scale of the domestic low-permeability/ultra-low-permeability oil reservoir is continuously increased, and the method has important strategic significance for relieving the contradiction between supply and demand of the crude oil in China. The natural elastic energy content of most domestic low-permeability oil fields is very low, energy needs to be supplemented in time, and almost all domestic oil fields adopt a water injection development mode to maintain the pressure in the stratum. From the related experience of the oil field which is put into production in China, the seepage resistance of a low-permeability reservoir is large, and the extraction degree is small. After statistics of low-permeability oil field development data which are put into development at home, the injection pressure of most of the liquid production wells is more than 10 MPa.
In a reservoir, the pressure of an upper rock stratum is mainly born by a rock framework and fluid in a hole, and because the energy in the stratum is continuously consumed along with the increase of the exploitation time in the production development process of an oil field, the pressure born by the rock framework is continuously increased, and then the rock framework is compacted and deformed to cause the reduction of permeability, the influence of confining pressure on the production process should be considered for a flat plate experiment of a low-permeability or ultra-low-permeability rock stratum.
The method for describing the fluid seepage rule in the oil reservoir by using the physical simulation flat plate model manufactured by using the real core outcrop is an experimental method with low cost, simple method and excellent effect. The flat-plate model experiment mainly researches an oil displacement mechanism, optimizes a displacement system, evaluates injection capacity, oil displacement effect and the like. The real situation of the reservoir underground is restored according to a similar principle.
