摘要(Abstract)：

塔里木盆地塔中隆起奥陶统鹰山组岩溶类型多样、结构复杂。以成像测井为主要手段,综合野外露头、岩心薄片和常规测井资料,研究塔中北斜坡中下奥陶统鹰山组岩溶结构特征;根据成像测井资料对单井进行刻画,分析岩溶结构垂向发育特征,提出鹰山组岩溶为潜水面控制的碳酸盐岩岛发育模式。结果表明:研究区整体识别出溶洞、溶孔、裂缝和溶孔—裂缝4种主要的岩溶结构单元,每种结构单元在成像测井及常规测井资料上响应特征不同。溶洞发育段在常规测井资料及解释数据交会图上响应特征明显。研究区发育至少3套溶洞,分别位于距不整合面5.0~20.0、40.0~100.0、150.0~200.0m埋深处。该研究结果为进一步研究鹰山组岩溶发育模式提供依据。
