The analysis of seismic data comes to the conclusion that the shortening of formations in a compressional basin mainly results from faulting and folding.

由地震资料分析认为，造成压性盆地地层缩短的原因主要有两方面：①断裂作用；②褶皱作用。

The sedimentary process of compressional basin is the peak period of hydrocarbon generation of middle and shallow formation, being favorable for the hydrocarbon preservation.

压陷盆地的沉积过程为中浅层生烃高峰期也有利于油气的保存；

Dayangshu Basin experienced multistage deformations, which is characterized mainly by extensional structures, and was superimposed by compressional structures and positive inversion structures.

大杨树盆地经历了多期变形作用，具有以伸展构造为主、并被挤压构造和反转构造叠加的构造特征。
