摘　　要：塔河油田南部地区自震旦纪以来发生过多期岩浆喷发活动,尤其是二叠纪岩浆作用面积大、影响范围广。岩浆活动带来大量热液流体,在侵位运移过程中对碳酸盐岩产生溶蚀改造,形成以溶蚀缝孔洞为主的储集空间。其发育分布主要受断裂带控制,岩性控制作用也较明显。为进一步认识这类储层,以钻井岩心和薄片观察为基础,从储层岩石学特征、储集空间类型及储层类型、储层发育分布特征等方面研究认识了塔河油田南部奥陶系热液成因碳酸盐岩储层的特征。Since Silurian, multiple magmatic eruption events have emerged in southern Tahe oilfield. Especially, magmatism during the Permian is characterized by a large area and extensive influence. Generating from these events, large amounts of hydrothermal fluid made carbonate-rock dissolution and reconstruction,and further formed many reservoir space dominated by dissolution fractures and caves during an invasion migration. For these fractures and caves, the development and distribution were affected by fault zones and lithology. In addition, based on some data from core analysis and thin-section identification, the Ordovician carbonaterock reservoirs with hydrothermal origin, southern Tahe Oilfield,are explored in terms of petrology, reservoir-space type, reservoir type, and reservoir development.
