摘　　要：塔河油田碳酸盐岩储层分布的强非均匀性、储集空间连通关系的复杂性以及油气充注成藏的多期次性,导致塔河油田奥陶系油气藏的油水关系极为复杂。对塔河油田南部盐下各类流体资料研究表明,丰富的油源是油气藏形成的物质基础,有利的区域构造位置控制油气运移,岩溶缝洞储集体的发育控制油气富集,封盖作用控制油气藏的纵向分布,多期次的充注控制油气的平面分布以及不整合面及断裂控制油气的聚集成藏等。The strong heterogeneity of the reservoir of the carbonate rock, the complexity of the connected component of the pore space and the multiple stages of the petroleum filling to form reservoir resulted in very complicated oil-water relation of the reservoirs of the Ordovician system in Tahe Oilfield. The analytical result of the various fluid information show that the rich oil sources is the material basis of the reservoir forming, the favorable areal structure location control the petroleum migration, the development of the karst control the oil/gas concentration, the sealing gland control the longitudinal distribution of the reservoir, the multiple stages of the petroleum filling control the lateral distribution of the reservoir, and the uncomformable surface and fault control the reservoir forming.
