摘要(Abstract)：

针对传统储层评价方法中人为主观性较强、计算过程复杂、结果分析不充分等问题,根据数据包络分析原理,探讨SBM-DEA模型在储层综合定量评价中的应用。实践表明,该模型在储层评价中具有以下优点:(1)能同时考虑多个正相关和负相关指标,无需事先给定评价标准及指标权重值,避免主观因素影响,具有较强客观性;(2)以线性规划为工具,无需进行指标无量纲化等数据预处理,有效简化评价过程;(3)评价结果介于0～1之间,除对评价单元进行排序、分类外,还可以提供评价非有效的原因及可改进信息。将其应用到苏里格气田苏X井区盒8下亚段低渗透气藏早期储层分类评价和刻画中,将研究区储层分为4类,其中Ⅰ,Ⅱ类为有利储层,总体评价结果与传统模糊综合评价结果具有较好对应关系,与气田生产实际及地质认识也基本吻合,并给出了评价实例非有效的主要差距及改进措施,表明该方法在实际应用中具有可信度及可行性,为实现类似高效、客观的储层评价提供了新的思路。
