In order to solve complicated faults imaging problem of the Dongpu oilfield,the authors utilized multi-step reverse time migration method and realized GPU accelerate parallel algorithm for overcoming the low compute efficiency disadvantage of RTM.The GPU accelerated multi-step reverse time migration method was successfully applied to complicated faults imaging processing.The RTM imaging result of Qianliyuan 3D data proved the technological advantage of RTM for complicated small faults imaging and Lanliao dip-angle faults imaging.Migration efficiency analyses demonstrate that RTM based on GPU accelerate algorithm can effectively improve the computational efficiency by 75 times.
