College of Geo-exploration Science and Technology��Jilin University��Changchun 130026��China
Conventional velocity analysis results of converted wave are inaccurate when amplitude change with offset existing in converted wave seismic record��especially polarity reversed�� Therefor��based on the consideration of AB similar coefficient velocity analysis of PP wave to resolve the AVO effection��the authors extend converted wave data with AVO phenomenon by AB similar coefficient method��and derive AB similar coefficient method to settle the converted wave with AVO phenomenon��which provide theoretical support to improve the accuracy in converted wave velocity analysis��
