摘　　要：塔中北斜坡奥陶系鹰山组的岩溶储层具有巨大的油气潜力。随着勘探和开发工作的细化,需要明确鹰山组内岩溶储层在空间上的展布形态。依据三维地震资料的反射特征,认为鹰山组顶部发育了四期次岩溶作用,经历了地层剥蚀—剥蚀与岩溶作用共存—岩溶发育—充填的成岩过程。各期次岩溶作用发生时潜水面逐渐上升,伴随有高构造部位的削蚀。提出了岩溶储层的多期次发育模式。The Ordovician Yingshan karst reservoirs are of great petroleum potential in Tazhong Northern Slope,Tarim basin. Further petroleum exploration needs to know more accurate spacial distribution of the karst reservoirs.According to reflection characteristics of 3D seismic data, it is shown that a serial of karstification have undergone inthe upper part of Yingshan Formation, which is a diagenetic process from denudation through coexisting denudationand karstification to karstification and then filling. Erosional truncation happened in structural highs as water tablesrose during every karstification. A multiphase development model of Yingshan karst reservoirs is proposed.
