| description | The invention provides a seismic integral method time migration method based on Spark. The seismic integral method time migration method based on Spark comprises the following steps: step 1, setting parameters for performing integral method pre-stack time migration; step 2, segmenting the input data and the output imaging range according to the parameters to form an input RDD; step 3, carrying out integral method time migration processing on the input RDD; and 4, merging the temporary imaging results RDD to obtain a final imaging result. According to the seismic integral method time migration method based on Spark, the defects in the aspects of temporary file processing, network communication and the like in the prior art are overcome, the parallel efficiency is further improved, and processing of mass data can be supported more stably.
