注水开发油田的采收率为注入水波及系数与驱油效率的乘积。其是衡量油田开发水平高低的重要指标,是指在一定的经济级限内和现代工艺技术条件下,从油藏中能采出的石油量占石油地质储量的比率,其大小与采出程度和驱油效率密切相关。其中,采出程度是指油田开发过程中任何时间内累积采油量占地质储量的比率,驱油效率是指从波及区中驱出的油的体积与油藏原始含油体
Oil recovery development of oilfield injection of water and the coefficient of flooding the product of the efficiency. It is a measure of the level of oilfield development is an important indicator refers to the economic level within a certain period and under the conditions of modern technology, can be extracted from the reservoir of oil in the proportion of petroleum geological reserves, its size and degree of recovery And oil displacement efficiency is closely related. The recovery rate refers to the ratio of accumulated oil production to geological reserves at any time during oilfield development. The displacement efficiency refers to the volume of oil driven out of the affected area and the original oil-bearing body
