摘要
对SEC标准下的水驱曲线法评估上市储量的基本原理与评估要点进行了分析,以渤海S油田H区为例对水驱曲线法评估结果进行了应用分析,并与递减法预测结果进行了对比,结果表明:水驱直线段的选择、单井产液能力、有效生产井数对水驱曲线法上市储量评估结果有较大的影响,水驱曲线法评估过程较递减法更灵活,评估结果也更符合油田长期开发的实际情况。建议在SEC上市储量评估中尽量引入水驱曲线法作为递减法的重要补充。
The basic principles and evaluation points were analyzed for the application of the wa- ter drive curve method in evaluating listed reserves under the SEC standards, and H area in Bohai S oilfield was taken as a case to analyze the evalua- tion results from the water drive curve method and make a comparison with the results from the de- cline curve method. These analysis and comparison have shown that. （1） The selection of linear por- tion in a water drive curve, the single-well liquid productivity and the active number of production wells may have greater impacts on the evaluation results of listed reserves from the water drive curve method; （2） Compared with the decline curve method, the water drive curve method may be more flexible in its evaluation process and more conformable to the oilfield reality of long-term de- velopment in its evaluation results. It should be suggested to introduce the water drive curve meth- od as an important complement of the decline curve method in the listed reserves evaluation under the SEC standards.
