The Joint Imaging of Primary and Internal Multiples

Abstract

Summary Multiples are real reflections from the underground interface, and if internal multiples can be effectively used, it can assist in illuminating shadowed areas that cannot be reached by primary., which is of great research value for the exploration and development of complex structural reservoirs. The single internal multiples imaging method is difficult to extract remove the illusion. Therefore, it is of great significance to study the joint imaging method of primary and internal multiples. In this paper, the feasibility of the joint imaging of primary and internal multiples is firstly verified. Then, the problem of opposite polarity between primary and internal multiples imaging is studied, and the problem of inconsistent polarity is well solved, so that the energy at the imaging interface is effectively compensated.
