Application of diminishing curve method in SEC standard evaluation of oil and gas reserves:A case study in Wangji Oil Field

摘要: SEC上市油气储量评估中已开发储量的评估常用的是递减曲线法,主要应用于油田开发中后期剩余经济可采储量的评估.通过递减曲线法在王集油田的应用分析认为,对于开发中后期的油田,在应用递减曲线法进行评估时,应根据油气田已有的开发生产规律和目前所处开发阶段,合理选择产量递减曲线类型和递减率,使其符合目前开发阶段油田实际开发趋势,达到评估结果客观、准确.Abstract: In the evaluation of proved developed reserves of SEC,the diminishing curve method was commonly used to judge the remaining economic recoverable reserves during the middle and late periods of oil field exploration.A case study was carried out in the Wangji Oil Field and proved that proper curve type and diminishing rate should be chosen based on the present exploration principle and stage.In this way,evaluation results will be more objective and accurate.
