【摘要】 恒流堵塞器是油田分层注水系统中的重要部件,在注水压力和地层压力变化时,它可以保证注水流量基本不变,从而达到恒流注水的目的。文中利用物理系统建模的通用方法—键合图法建立了恒流堵塞器的模型,通过仿真软件20-SIM进行了仿真,并且分析了物理参数对性能的影响。更多还原

【Abstract】 Constant flow blanking plug is an important component in the layered water injection system of oil field, when the injection pressure and strata pressure are changing, it can ensure that the flow rate of injection is nearly constant, so getting the purpose of constant flow injection. In this article, the model of constant flow blanking plug is established by the method of bond graph which is usually used in modeling of physical system, simulation is also performed using the simulation software 20- SIM, and the influence of physical parameters to performance are analyzed.更多还原
