The application of pre-stack migration technique in complex Fault-blocks of Zhongyuan oilfield
叠前偏移技术在中原复杂断块区的应用

With further exploration and development of oil & gas and the development of relevant subject,Imaging in complex geological structure and seismic lithology has become urgent problem to be solved.Aiming at the characteristics of seismic data from complex fault-blocks in Zhongyuan oilfield,the selection of key parameters in pre-stack migration and migration approaches were meticulously studied.With the application of pre-stack migration technique in Zhongyuan oilfield,final results prove the effectiveness of this technique.
