Two-dimensional survey line seismic data closure error correction method and processing terminal

The invention relates to a two-dimensional survey line seismic data closure error correction method and a processing terminal. The two-dimensional survey line seismic data closure error correction method comprises the steps of: step 1, acquiring two-dimensional survey line seismic data, sorting two-dimensional survey lines according to construction features, and enabling the two-dimensional surveylines with the same construction features to be the same in sorting; step 2, grouping all the survey lines according to a sorting result, so that the two-dimensional survey lines in the same group are not intersected, the two-dimensional survey lines in different groups are intersected, and a plurality of groups of survey lines are obtained; and step 3, calculating a correcting value between thecurrent group of survey lines and the next group of survey lines, performing correction between the current group of survey lines and the next group of survey lines according to the correcting value,combining the two groups of
