Embodiment Construction

[0031] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0032] Bottom water reservoirs in my country account for a large proportion of all types of reservoir reserves, and the reserves are quite abundant. In addition to a large number of natural bottom-water reservoirs, as oilfields enter secondary and tertiary production, the development characteristics of more oilfields tend to tend to bottom-water reservoirs. Bottom water reservoirs have the characteristics th...

Description

technical field [0001] The invention relates to the technical field of oil and gas development, in particular to a system and method for realizing recovery simulation experiments of edge and bottom water reservoirs. Background technique [0002] Bottom water reservoirs in my country account for a large proportion of all types of reservoir reserves, and the reserves are quite abundant. In addition to a large number of natural bottom-water reservoirs, as oilfields enter secondary and tertiary production, the development characteristics of more oilfields tend to tend to bottom-water reservoirs. Bottom water reservoirs have the characteristics that all oil-bearing areas are in contact with bottom water. This is not only the advantage of bottom water reservoirs in development than other reservoirs, but also the difficulty in the development of bottom water reservoirs. [0003] According to the development experience of bottom water oilfields at home and abroad, the key technolog...
