摘要(Abstract)：

一般认为柴西地区的扎哈泉油田新近纪砂坝储层的物源与古近纪的物源一致，但前人对古近纪的物源有不同的观点，从而造成扎哈泉地区新近纪物源认识不清，影响了该区沉积相与储层构型的研究。运用SPSS软件，对该区新近纪有限的重矿物资料进行聚类分析，进而研究不同类别样本的重矿物分布特征，并与铁木里克物源和祁漫塔格—东柴山物源进行了对比。研究结果表明：扎哈泉地区新近纪的物源来自祁漫塔格—东柴山，不存在两大物源在此交汇混合的情形，且该区内部又可以分为两个次级物源，一个仅仅覆盖扎2井区、扎401井区和扎7井区，另一个覆盖全区，两个次级物源存在交汇混合。该项研究厘清了扎哈泉地区新近纪物源的归属，为该区砂坝构型研究，特别是砂坝的迁移叠置方式研究提供了有力的参考。
