油水关系特征及油水分布状况是油藏描述的重要内容之一。正确认识油藏的油水分布特征，对于油藏的方案编制、注水开发等起着至关重要的作用。潜山油藏不同于碎屑岩油藏，由于其特殊的储层结构以及储集空间类型，导致该类油藏中流体空间分布更具复杂性。以塔里木盆地塔河油田奥陶系油藏为例，根据单井以及井组的开发特征，结合该区储层分布特点，总结归纳了缝洞型碳酸盐岩潜山油藏油水关系模式，主要有普通式、隔油式、隔水式、复合式以及纯油式；针对每一类模式，实例分析了典型井以及井组的生产或见水特征。

Oil water distribution is an important content for reservoir description, and it is important for the reservoir production. Buried hill reservoirs are not as same as clastic ones because of their special reservoir texture, and the distribution of liquids is more complex in them. Taking the Tahe reservoir as example and according to reservoir distribution and production data, this paper summed up several patterns of buried hill reservoir, including general mode, intersected water mode, intersected oil mode, multiplex mode, and pure oil mode. For every mode, production or water breakthrough characteristics in wells are analyzed.
