摘要：

挤压构造的动力学为板块与板块碰撞形成造山带,在造山带一侧或造山带内部形成挤压型盆地,这些盆地在挤压应力作用下,形成叠瓦逆冲、复合逆冲、多层次滑脱逆冲、多产状逆冲断裂构造组合。文中对与挤压逆冲有关的褶皱构造样式——断弯、断展、 断滑褶皱构造进行了描述，指出在加强非背斜构造样式勘探的同时,也应加强背斜构造样式的勘探。油气资料显示80%~90％的油气生产来自背斜构造样式的油气田,面积大、幅度高的挤压构造是形成大、中型油气藏的地质条件。

Abstract:

 Contraction structural stress resulted from plate to plate collision causes the formation of orogenic belts and contractive basins forming in the one side of the orogenic belt or the interior of it. Under the effect of the contractive stress, various structural styles are formed, including imbricate thrusting, complex thrusting, multiplelevel detachment thrusting, and composite thrust structures with various attitudes. The paper describes the fold structural styles related to contractive thrusting: faultbend folds, faultpropagation folds, and detachment folds, and proposes that we should not only consider the nonanticline structure as the main exploration targets, but also pay more attention to the anticline in future exploration because 80%90% of total oil production came from anticlines, especially for contractive structures with larger closure area and high amplitude that are the basic geologic conditions for the formation of larger and medium reservoir.

Key words: contractive fractured structure, seismic interpretation, anticline, nonanticline structure, petroleum structural style
