【摘要】 周期注采机理及数学模型研究是从以下四种注水和采油的生产状态出发:稳定注水—稳定开采;稳定注水—周期开采;周期注水—稳定开采;周期注水—周期开采,深入探讨周期注采的机理,建立完整的数学模型,为周期注采在油田开发中的进一步应用提供理论依据,最终达到提高采油效率和经济效益的目的。更多还原

【Abstract】 Injection-production mechanism and mathematical model study was from the following four types of water injection and oil production status: the stability of water-the stability of the exploitation;the stability of water-cyclical oil production;cycle of water injection-the stability of the exploitation;cycle of water injection-cycle oil production,discussing injection-production cycle mechanism and establishing of a complete mathematical modelwhich provide a theoretical basis for further applications for injection-production cycle in the oil field development theoretical Ultimately to improve oil recovery efficiency and economic efficiency.更多还原
