摘　　要：通过对焉耆盆地油田水的基本特征及其在平面和纵向上的变化规律研究,阐述了油田水中元素与油气生成、运移、聚集和保存相关的一些特征,并依据油田水无机组份、化学系数以及总矿化度等因素,将焉耆盆地划分为四个水文地质区带。其中宝中、宝北三工河组为阻滞带,地层封闭性强,油气藏保存条件好;本布图构造带、种马场构造带、宝南区块为缓慢交替带,油气藏遭受了不同程度的破坏。The relationship between elements in oilfield water and hydrocarbon generation,migration,accumulation and preservation is discussed based on the basic features of oilfield water and the vertical and lateral changing pat-tern in Yanqi basin.According to the inorganic compo-nents,chemical factors and gross salinity of oilfield water,Yanqi basin is divided into four hydrogeological zones.The detention zone is located in the Sangonghe Formation in Baozhong and Baobei blocks where sealing potential is high and preservation conditions are good while the slow interchanging zone is located in Benbutu and Zhong-machang structural zones and Baonan block where oil and gas reservoirs are damaged to different degree.

关 键 词：焉耆盆地 油田水 油气聚集 水文区带 油气保存
