塔里木盆地构造演化与构造样式

Evolution and Tectonic Patterns of Tarim Basin

塔里木盆地的发展演化受不同时期板块构造背景的控制,形成了陆内裂谷、裂陷槽、克拉通内拉张盆地、克拉通内挤压盆地、被动大陆边缘盆地、弧后拉张盆地、弧后前陆和周缘前陆盆地等多种原型盆地并相互叠加和改造。盆地中存在挤压、引张、扭动和叠加构造样式,可以形成良好的圈闭构造。盆地中的大型隆起带是主要的油气聚集带,前陆盆地褶皱-冲断带具有较好的油气前景。

The evolution and development of Tarim basin were controlled by the background of the plate tectonics in different periods, forming various types of primary basins, such as intracontinental rift valleys, rifted trenches, tensional basins and compressional basins inside craton, passive continental margin basins, back-arc-torsiono-extentional basins and others, which were superposed and transformed by each other. In the basins exist compressional, extentional, torsional and superposed tectonic patterns, which could form favourable trap struc-tures. The uplifted zones in the basins are main oil -gas accumulated zones, and the fold -thrust zones in foreland basins show the better oil-gas prospects.
