库车断层相关褶皱的切角检验

Testing of Cut-off Angles of the Kuqa Fault-related Folds

库车再生前陆盆地地下构造复杂,正确的构造解释就成为了解盆地成因机理和油气圈闭的关键所在。利用断层相关褶皱几何学理论建立的构造几何模型,对库车地震剖面断层相关褶皱进行了切角检验,结果表明切角实测角度值与理论角度值一致,从而证明了在库车地区所建立的断层相关褶皱构造模型的合理性。

The subsurface structures of the Kuqa rejuvenated foreland basin are really complex, so a correct interpretation of them is the key for understanding the genesis of the basin and hydrocarbon traps. With the geometry models of structures built on the basis of the theory of fault-related folds, the authors have tried to interpret and predict the complex structures effectively. The results show that measured cut-off angles of the fault-related folds of the seismic profiles in the Kuqa area agree well with the theoretical values. Thus the established fault-related folding structure models of the Kuqa rejuvenated foreland basin are verified to be reasonable.
