摘要: 在修正水驱动态储量计算方法基础上,结合具体水驱开发油藏实例,提出水驱开发油藏高含水期采收率综合评价技术,合理评价油藏当前和最终的采收率,从而论证油藏开发极限潜力,为开发调整提供依据论证。Abstract: On the basis of modifying the calculation method of water -drive dynamic reserve,examples of water-drive reservoir are discussed for the study on the overall evaluation of recovery ratio at high water cut of water-drive reservoir to rationally evaluate the current and the finally recovery ration. Accordingly,the development limit of reservoir is demonstrated, which offers the basis for development adjustment.
