摘要
产量递减曲线法是常用的上市储量自评估方法。由于递减趋势阶段性变化特征以及递减类型选取的灵活性,使得递减曲线法的应用较为复杂。根据多年上市储量评估经验,总结了如何在SEC(美国证券交易委员会)准则下合理运用产量递减曲线法进行储量评估,并对最小储量评估单元为单井、区块或全油气藏、常规油气藏及特殊油气藏等不同情况下的递减曲线法应用进行了描述。通过大量的实例分析,论述了应用产量递减曲线法进行储量评估时如何预判未来生产变化趋势,以及如何采用最可靠的评估,最终实现在确保储量"正增长"的同时获取最大合理评估储量,以满足"合理确定性"的要求。
The production decline curves method was commonly used in the listed reserves assessment.However,the actual application was more complex due to the stage changes of the production decline and the flexible selection of the decline types.The applications of production decline curves method to the listed reserves assessment under SEC(Securities and Exchange Commission) standards were systematically summarized based on many years of experience,including conventional reservoir and unconventional reservoir.Based on the production decline curves method,the future production trend would be pre-judged,and the most reliable assessment would be achieved to balance the positive growth and the most reliable assessment reserves,thus meeting the requirement of'reasonable certainty'.
