摘要:
鄂尔多斯盆地下古生界风化壳储层是具有高度的非均质性及繁多的储集空间类型。下古生界风化壳气藏测井评价的关键是通过测井方法对储层进行精细分类划分有效储层,对工业性产层与低产、低效层的界定。基于储层分类的概念,根据常规测井响应,采用聚类分析和判别分析理论,将鄂尔多斯盆地靖边地区下古生界风化壳储层划分为裂缝-溶孔型(Ⅰ类)、孔隙型(Ⅱ类)、裂缝-微孔型(Ⅲ类)等3类;论述了各类储层的主要特征,分类方案考虑了测井资料的可分辨性。在此基础上建立基于聚类分析及判别分析的储层分类判识模型,对测井资料进行归一化、标准化处理,提取能有效反映储层特性的表征参数。实际应用效果表明,分类结果与试气结果吻合较好,判识符合率达到80%以上,使常规测井资料得到了更深入、更广泛的应用。
