摘　　要：针对水驱特高含水期油田的开发特点,根据盈亏平衡原理建立了不同成本构成的油井经济极限含水计算模型。实际测算了大庆某区块不同油价下的经济极限含水,并将油井进行了经济效益分类。该方法为确定油井关井界限,指导油田经济有效开发提供了重要决策依据。According to the waterflooding characteristics in extra-high water cut stage of oilfield,a calculation model which is based on profit and loss balance principle has been created.This model can be used to identify the economic limit water cut of producers with different cost component.With the use of this model,the economic limit water cut in a development block of Daqing Oilfield with different oil prices has been calculated,and according to the economic benefit,producers have been classified into different group.This model is a significant basis of well shut-in and oil-field development.
