松辽盆地十屋—德惠含气带反转构造分析

ANALYSIS OF INVERSION STRUCTURES IN SHIWU DEHUI GAS BEARING ZONE OF SONGLIAO BASIN

松辽盆地,十屋—德惠含气带自早白垩世以来经历了裂谷期末和坳陷期末两期构造正反转，形成了众多反转构造，主要有６种构造样式和两种组合类型。分析认为本带反转构造的形成演化机制有滑脱褶皱和断弯褶皱两种。文章分析了主要反转构造的反转强度。

Since K 1 Shiwu Dehui gas bearing zone of Songliao Basin has went through two positive structural inversion terms and formed many inversion structures which have 6 structural styles and 2 combination types. The authors suggust that there are two mechanism of formation and evolution for the inversion structures in the zone, they are detachment fold and fault bend fold. The inversion extent of some major inversion structures is calculated and the relationship between inversion structure and hydrocarbon is chiefly probed in this paper.
