摘　　要：通过对塔河油田9区奥陶系凝析气藏试采和地震属性分析,9区奥陶系凝析气藏储层发育。可将塔河油田9区奥陶系碳酸盐岩储集空间类型划分为:溶洞、裂缝、孔隙3类。岩石薄片中偶见孔隙型储集空间类型,但发育较少,不具备有效储集条件。结合地震属性类储层预测,进一步将区内奥陶系储层划分为岩溶缝-洞型储层、洞穴型储层、裂缝-孔洞型储层3类。通过对研究区奥陶系储层发育控制因素的分析,表明区内奥陶系储层主要受断裂、裂缝、岩溶作用及储集体局部构造发育程度控制,这些因素相互影响,共同控制区内奥陶系储层的发育。By studying trial mining and seismic attribute analysis of Ordovician condensate gas reservoir in block 9 of Tahe oilfield,the reservoir of Ordovician condensate gas reservoir in block 9 of Tahe oilfield is developmental,the Ordo-vician reservoir and permeable space can be divided into cave,fracture,and pore.In the rock flakes,Porosity reservoir space occasionally found,but less developed,which does not have an effective reservoir conditions. Based on the classi-fication,the type of Ordovician reservoir can be divided into the reservoir of karstification fractured-vug,the reservoir of karstification cave and the reservoir of fracture.The Ordovician reservoirs in the region mainly are controlled by faults,fractures,karstification,and degree of development of local structures,which affect each other and commonly control the development and the distribution of the reservoirs.
