摘要: 通过对吐哈盆地台北凹陷红南—红西地区负压系统流体封存箱形成的综合研究表明:在不具备增压作用的地质条件下,没有大幅度剥蚀的地区负压系统的成因主要与烃类扩散作用有关;而超压实作用与小幅度构造抬升加剧了负压系统的形成。此外,油气的运聚和成藏与负压系统的成因及封存箱的形成密不可分、相互依存。

Abstract: A comprehensive analysis of the underpressured fluid compartments in Hongnan-Hongxi area of the Turpan-Hami Basin indicated that, within this area which had not experienced prominent denudation, the genesis of underpressured compartments were mainly related to hydrocarbon diffusion. In addition, over-compaction and small-range tectonic uplifting had intensified the underpressure. It is shown by this work that petroleum migration and pool formation has a close relationship with these underpressured compartments.

Key words: underpressure, compartment, genesis, light hydrocarbons, diffusion, Turpan-Hami Basin
