Description

technical field [0001] The present invention relates to the fields of petroleum exploration and development and reservoir engineering, in particular to the field of reservoir engineering experiments, specifically a high-pressure outcrop plane model experiment system, which is suitable for detecting real underground pressure environments in laboratory reservoir fluid displacement simulations The pressure field changes and flow field changes in . Background technique [0002] In order to study the mechanism of fluid seepage in reservoirs, fluid displacement experiments in the laboratory, core displacement experiments and plane model displacement experiments have become the main means to study the law of subsurface fluid flow and development characteristics. [0003] For medium-high permeability reservoirs, due to the high permeability of the model and core, the displacement pressure of the experiment is relatively low, so high pressure is not required in the experiment, so the...

Problems solved by technology

[0004] At present, many people have tried to carry out high-pressure experiments of two-dimensional physical models in high-pressure chambers, but due to the complicated operation of the process and unsuitable experimental methods, this type of experiment cannot be promoted, and it is impossible to conduct batch experiments and provide complete sets of data for scientific research.
