塔里木盆地塔河油田成藏史与成藏机制

通过对塔河油田不同区块、层位油气藏的圈闭形成期、油气注入期进行分析,认为塔河油田不同性质的原油。成藏期始于海西运动晚期，延续至喜马拉雅运动期,分为海西运动晚期、燕山-喜马拉雅运动早期和喜马拉雅运动晚期三个阶段。归纳出塔河油田的成藏机制具有长期持续供油、多层位有效储盖组合匹配、多期成藏、油气面貌复杂的特点。

The Reservoir-Formed History and Mechanism of Tahe Oilfield in Tarim Basin

The reservoir forming stages with different properties of crude in Tahe oilfield are believed to originate from the late Hercynian movement and lasting to Himalayan Movement.It can be divided into the late Hercynian,Yan-shan-early Himalayan and late Himalayan movements,through analyses of the traping stages of different blocks and horizons of hydrocarbon reservoirs as well as their hydrocarbon-input stages.The reservoir-formed mechanism in Tahe oilfield is characterized by long terms of continuous crude supply,multi-horizon effective reservoir-seal assemblages,multistage formation of reservoirs and complicated hydrocarbon occurrences.
