| 英文摘要 | Multiple elimination using iterative inversion method includes two steps: prediction and subtraction. During matching subtraction, when multiple events are not orthogonal to primary events and the signal after multiple elimination has no minimum energy, the least-square adaptive matching filtering method can't get correct matching results and so multiple elimination will produce some deviation. In order to overcome the two problems above, I propose the equipoise multichannel adaptive matching filtering method using L1-norm in this paper. Through poising seismic records in the direction of space, this method avoids the assumption that multiple events are orthogonal to the primary events. Because L1-norm is robust to large amplitude differences, this method can effectively deal with the problem that the signal after multiple elimination has no minimum energy. Results of multiple suppression with simulated data and field data show that this method can effectively and correctly subtract multiples. |
