摘　　要：探井效果评价是勘探管理与决策分析中的一项基本内容,但目前常用的探井效果评价指标并不能真正反映当年探井的实际效果。根据济阳坳陷多年的勘探实际,综合考虑探井与储量之间历史关系的复杂性、勘探产出形式的多样性,提出了一种新的评价当年探井效果的指标——当年单井效果综合评价指标。其具体确定过程可分为3个步骤:①不同形式的勘探产出向探明储量的折算;②当年探井对预期探明储量的贡献分析;③当年平均单井效果计算。从实际应用对比来看,该指标能最大限度地反映出当年探井对储量的实际贡献,可对当年探井勘探效果作出更客观的宏观评价。Effect evaluation of exploration wells are very important for exploration management and decision analysis,but the present e-valuation index can not reflect the actual effect of the exploration wells in those years.Based on the fact of exploration in Jiyang Depression,and the complex relationship between exploration well and reserve,together with the pattern diversity of exploration output was taken into account,a new effect evaluation index of exploration wells named comprehensive effect evaluation index of single well in those years has been put forward.The value of the index has been calculated by three steps;①converting other patterns of exploration output into proven reserves;②analyzing the contribution of the exploration well the same year to the expected proven reserves;③calculating the average single-well effect at the same year.In contrast with the other evaluation methods,this index can show the practical contribution of the exploration well the same year to expected proven reserves at maximum degree,and can give more impersonal macroscopic effect e-valuation for the exploration well the same year.
