Abstract

The invention provides a carbon dioxide flooding multi-stage streamline injection production simulation device and simulation method, and relates to the technical field of carbon sequestration and petroleum exploitation. The carbon dioxide flooding multi-stage streamline injection production simulation device comprises a shell, a simulation reservoir module for simulating a displacement process, and a tubular column module for forming an injection production channel with the simulation reservoir module, the simulation reservoir module and the tubular column module are stacked and arranged in the shell, the shell is provided with an opening for mounting the simulation reservoir module and the tubular column module, the simulation reservoir module comprises a simulation reservoir and at least three injection production hole tubular column modules in communication with the simulation reservoir, the tubular column module is further configured to change a multi-stage injection production relationship by controlling opening and closing of a plurality of valves, thereby completing simulation of a current well pattern to a target well pattern. The carbon dioxide flooding multi-stage streamline injection production simulation device and simulation method can simulate carbon dioxide flooding and dynamic geological sequestration processes in a complex well pattern environment.

Description

technical field [0001] The embodiments of the present invention relate to the technical fields of carbon sequestration and oil exploitation, and in particular to a carbon dioxide flooding multi-stage streamline injection-production simulation device and simulation method. Background technique [0002] Carbon dioxide flooding technology is not only a widely used carbon sequestration and utilization technology, but also one of the relatively mature enhanced oil recovery methods. Carbon dioxide has the characteristics of easy miscibility with crude oil and low viscosity, which makes carbon dioxide have good fluidity in the reservoir, and can reduce the viscosity of crude oil and the interfacial tension of oil and gas, thereby improving the fluidity of crude oil and oil displacement efficiency; therefore, carbon dioxide is used as an oil displacement agent , not only helps to enhance underground oil recovery, but also realizes the dynamic storage and utilization of carbon dioxid...
