| Zusammenfassung: | A method for optimizing chemical cold recovery of extra-heavy oil reservoir includes as the steps of: S1, setting up a numerical simulation model of core scale chemical flooding, fitting water flooding experiment and chemical flooding experiment to numerical simulation model of core scale chemical flooding; S2, the using fitting core scale chemical flooding numerical simulation model to obtain single well group scale chemical flooding numerical simulation model, carrying out chemical combination flooding optimization research and designing numerical simulation prediction scheme; S3, establishing the three-dimensional geological model and the dynamic numerical simulation model of the test area, simulating and calculating the development effect of the test area according to the numerical simulation prediction scheme, and optimizing the chemical cold recovery method of the extra-heavy oil reservoir according to the results. A CMG numerical simulation software is use for numerically simulating that effect of inje |
