Zusammenfassung: | The invention discloses a quantitative injection-production balance adjustment method based on water drive leading edge control, which comprises the following steps: judging a high-pressure region, abalance region and a low-pressure region in different strata of an oil field, and performing systematic adjustment on the high-pressure region and the low-pressure region according to injection-production balance adjustment key indexes; performing plate drop point drawing on current development injection-production flow pressure and injection-production quantity, adjusting a well group to be in abalanced state under repeated or multi-moment rule adjustment, and releasing the maximum productivity; considering Injection-production wells in a block systematically, determining the positions of the front edges of well groups with different water contents according to the water flooding front edge oil displacement theory, forming an injection-production balance index adjustment matrix, and realizing injection-production |
