Basin deep reservoir rock and fluid interaction simulation apparatus and application method

Abstract

The invention discloses a basin deep reservoir rock and fluid interaction simulation apparatus and an application method. The basin deep reservoir rock and fluid interaction simulation apparatus comprises an automatic control unit, a heating unit, a pressurizing unit, an analysis metering unit and a peripheral auxiliary unit, wherein an output end of the automatic control unit is separately electrically connected with input ends of the heating unit, the pressurizing unit and the peripheral auxiliary unit in a single direction, and an output end of the analysis metering unit is electrically connected with an input end of the automatic control unit in a single direction. By virtue of the cooperation of the automatic control unit, the heating unit, the pressurizing unit, the analysis meteringunit and the peripheral auxiliary unit, the basin deep reservoir rock and fluid interaction simulation apparatus solves the problems that the fluid pressure, static rock pressure and confining pressure of the reservoir rock are not matched with the actual geological conditions, resulting in unreasonable evaluation on the interaction of the basin deep reservoir rock and fluid, and reducing the accuracy and precision of parameters after the interaction of the rock and fluid.

Description

technical field [0001] The invention relates to the technical field of oil and gas accumulation mechanism and reservoir evaluation, in particular to a simulation device for interaction between rock and fluid in deep basin reservoirs. Background technique [0002] The interaction between reservoir rock and fluid is a very complex geochemical process, which is controlled by many factors such as minerals, formation water and physical and chemical conditions in the reservoir rock environment. The most critical is the interaction between minerals and pore fluids. effect. Fluid flow is the key factor affecting diagenesis. The distribution of diagenetic minerals in sandstone is related to particle size and effective porosity during deposition. The above parameters are also related to permeability and fluid flow. The diagenesis of reservoir rocks such as cementation and metasomatism is A function of the relationship between the solid phase and the pore fluid. This process is very ...

Problems solved by technology

[0005] The object of the present invention is to provide a rock-fluid interaction simulation device for deep reservoirs in the basin, which can realize the fluid pressure, rock-static pressure and confining pressure that match the actual geological conditions, and improve the accuracy and accuracy of rock-fluid interaction evaluation parameters. The advantage of accuracy solves the problem that the fluid pressure, static rock pressure and confining pressure of the reservoir rock do not match the actual geological conditions, which leads to unreasonable evaluation of the interaction between the rock and fluid in the deep reservoir of the basin, reducing the The problem of the accuracy and precision of the parameters after the interaction between the rock and the fluid is solved
