摘要：
Parabolic Radon transform is widely used for suppressing and removing multiple waves in pre-stack seismic data.Although parabolic Radon transform in mixed domain can well suppress multiples,it still needs a long time when processing seismic gathers larger and larger.In this paper, first we use the GPU to optimize the parabolic Radon transform algorithm in parallel,and use the CUDA library and other optimizing techniques to accelerate the most time-consuming Fourier transform and algebraic operations to nearly 13x speedup over serial execution in the calculating process; then based on the CPU-GPU heterogeneous platform,we propose a CPU-GPU parallel scheme,which makes full use of computer hardware,to realize the parabolic Radon transform parallel algorithm through CPU multi-threading and multiple GPUs in parallel.The speedup can be nearly 30x over serial execution. © 2020, Editorial Department OIL GEOPHYSICAL PROSPECTING.
