Study on Reasonable Injection-Production Parameters of Water-Flooding Reservoir: A Case Study of Daqing Oilfield

This paper, by conducting comprehensive analysis on water-flooding reservoir, intensively studied and discussed the characteristics of geological development, determined evaluation indexes development effect, carried out research from five steps, first is introduction part, it conducted indepth study discussion background, significance, literature review, methods four aspects. The second outlined related theory optimization principle mechanism injection-production parameters, distribution remaining oil two third analyzed current situation reasonable reservoirs in Daqing Oilfield reservoir deposition. fourth evaluated effect combined water cut, changing conditions production predicted recovery ratio. fifth parameters water- flooding oilfield design separated layer injection plan, maintaining level formation pressure, plan ratio rate three aspects, provides theoretical guidance for later targeted excavation reservoirs.
