| 摘 要： | 中国西北部发育有塔里木、准噶尔、柴达木、吐哈等四大含油气沉积盆地和众多的中小型含油气沉积盆地.现今盆地均是周缘造山带隆升后形成的地理型盆地,盆地基底均老于周缘造山带隆升时期,沉积盆地均具有造山型盆地性质.前人的研究表明周缘造山带的造山运动不仅给盆地提供了丰富的沉积物,同时控制了形成、改造和调整盆地的构造.笔者以相邻造山带构造演化对沉积盆地沉积、沉降、构造活动和热活动等特征的影响,特别是盆地边缘的影响研究为基础,在造山型盆地概念的基础上,系统讨论了造山带构造演化对含油气盆地油气生、储、盖、圈闭、运移和保存等方面的影响.

| Abstract: | There are four petroleum basins including the Tarim, Junggar, Qaidam and Turpan-Hami basins, and a number of medium- and small-sized petroleum basins in northwestern China. Nowadays, all the basins are geographic basins formed following the uplifting of peripheral orogenic zones. The authors contend, on the basis of the tectonic effects of the orogenic zones on deposition, subsidence, tectonism and thermal activity of sedimentary basins in integration with the previous data, that the orogenesis of the peripheral orogenic zones have not only provided abundant sediments for the basins but also exerted an important effect on the formation and evolution of the structures in the basins, especially the orogenic effects on the source rocks, reservoir rocks and cap rocks as well as the trapping, migration and preservation of oil and gas. |
