盆地基本构造样式与天然气成藏

文章概述了近２０ 年来大陆构造与构造样式的研究进展。提出按照断裂的基本类型并结合大地构造环境的控制作用， 将沉积盆地分为伸展盆地（ 引张型） 、走滑盆地和克拉通盆地三种主要类型，并分别简述了它们各自的构造样式。然后，对不同构造样式的成藏特征、成藏类型及成藏带（ 区） 分布进行了总结。并强调指出，在不同性质的盆地和盆地演化的不同阶段，可以形成不同的构造样式；而不同的构造样式组合，又相应地形成不同类型的天然气藏。

THE STRUCTURAL PATTERNS AND GAS RESERVIORS-FORMING IN SEDIMENTARY BASINS

Research advances of continental structures and structural pattern for the past two dacades are reviewed in this paper.In terms of basic types of fracture and in combination with control of geotectonic environment,sedimentary basins can be divided into three main types:tensional(extension-type),strike-slip and craton basins,and their structural patterns are briefly described respectively.Secondly,characteristics,types and belt(zone)distribution of oil and gas accumulation-forming of different structural patterns are summed up.It is emphasized that,in different stages of basins of different properties and basinal evolution,different structural patterns may be formed;and different associations of structural pattern can form different types of gas reserviors correspondingly.
