Seismic integration method time migration method based on Spark

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. 本发明提供一种基于Spark的地震积分法时间偏移方法，该基于Spark的地震积分法时间偏移方法包括：步骤1，设置进行积分法叠前时间偏移的参数；步骤2，根据参数，对输入数据和输出成像范围进行切分，构成输入RDD；步骤3，对输入RDD进行积分法时间偏移处理；步骤4，合并临时成像结果RDD，得到最终成像结果。该基于Spark的地震积分法时间偏移方法克服了
