Improper initial value will result in errors of low frequency component, relative wave impedance and stratumthickness to cause pitfalls of seismic data interpretation.
Lithology, rock stratumthickness, fracture process, structural stress field, local structure, stratum load and karst process are all main controlling factors for the development of the rift.
岩性、岩层厚度、断裂作用、构造应力场、局部构造、地层负荷与岩溶作用是控制裂缝发育的主要因素。

Ordos basin is the second depositional basin and significant resource base in China. It is characteristic of widespread, mass oil-bearing stratum, great oil layer thickness and so on.
