Research the larger volume of heterogeneous reservoir seismic wave equivalent theory. Using the "short-range exact  and long-range equivalent" multi-scale method to carry out simulation, imaging and inversion method and technical research of oil reservoir of seismic response. 

Main results: Asymmetric travel-time pre-stack time migration theory, prediction of multi-scaled internal multiples and fluctuations equivalent theory, 3D pre-stack time migration method and technology based on GPU, 3-D reverse-time migration method and technology based on GPU, 3D TTI media reverse-time migration method and technology based on GPU, 3D full waveform inversion method and technology based on GPU.  

Oriented cooperation: Oriented oil exploration and exploitation, cooperating with CNPC, CNOOC, and SINOPEC.
