Gird platform for seismic data parallel processing and its application

To meet the demands of mass data processing and high performance integration of resources in geophysical prospecting field, a distributed parallel processing platform based on grid technology is constructed. The architecture and key technology of the platform is described in detail. The platform, which includes two virtual organizations, was successfully deployed. Wave field forward modeling of the Marmousi model, fuzzy clustering data division strategy based pre-stack depth migration, and integral method pre-stack time migration were parallelly processed on the platform. The stability of the platform and the effectiveness of the parallel task partition strategy were proved. The efficiency was comparable with the traditional parallel platform. The platform can be applied to larger scale resources to expand the scale of parallel processing, improve resource utilization, and reduce the time of data processing.
