渤海油田上市储量通常采用SY/T 5367-2010 《石油可采储量计算方法》中第三种水驱曲线进行评估,由于评估时不考虑未来投资、井数变化等影响,不符合SEC准则“获得分年产量进行经济评价”的要求。针对这一问题,对该常规水驱曲线部分参数计算进行了四方面改进,改进后的水驱曲线法经C油田实际生产资料采用历史追溯评估和多方法评估验证符合SEC准则。6个高含水油田的推广应用表明,该方法减少了评估工作量，提高了评估效率,同时增加了已开发储量，降低了折旧摊销成本。
The third water drive curve in "SY / T5367-2010 The Estimated Method of Oil Recoverable Reserves" is usually adopted for the assessment of listed reserves of Bohai oilfield company. Not considering the effect of the future investment and changes of the number of wells, the evaluation does not meet the SEC guidelines - "To obtain the annual output for economic evaluation".Concerning this issue, part of the parameters of the conventional water drive curve is improved in four aspects.After improvement, the water drive curve method is verified by historical retrospective and multi-method evaluation in the actual production data of oilfield C, which meets the SEC guidelines.The application in the six high waterflooded fields shows that the method has a small workload and improves the efficiency of the assessment, while increasing the developed reserves and reducing the depreciation and amortization costs.
