Only good angular trace gather in AVO technique can be used to determine petrophysical parameters and to detect oil or gas. Presented here is iterative curved ray method, or straight line fitting method which converts CDP trace gather into angular trace gather. No matter how complicated a formation may be,this method can describe it approximately. An example of North China Oil Field proves it feasible that people use iterative curved ray method to produce angular trace gather.
