Problems solved by technology

[0002] The currently used combustion displacement physical simulation device adopts a long cylindrical structure, which can simulate the combustion displacement situation, but it also has the following shortcomings or deficiencies: ① only one-dimensional simulation experiments can be carried out, and the research parameters are limited to the basic combustion parameters of the oil layer , such as: crude oil ignition point, fuel content, H / C ratio, air consumption, one-dimensional simulated recovery factor, etc.; ② can only study the axial propulsion law of the fire front, and cannot evaluate the planar propulsion and distribution of the fire front ③The mechanism of combustion flooding cannot be deeply explored, and it has little guiding effect on on-site reservoir management, which directly affects the development prospect of combustion oil recovery technology
