摘要
In marine seismic exploration, a long array of sources efficiently transfers energy along the reflection path. Multiple reflection rejection is achieved by normal move-out discrimination at selected trace distances for each reflection. The length of the source array is changed in accordance with the geological characteristics of the sub-surface formations being explored and the reflection time of reflections from formations of interest. A split source array allows one section of the array to be moved with respect to the other to change the overall length of the array without changing the number of sources which are fired. Primary to multiple reflection enhancement is obtained by selecting only traces having source to detector offset distances with a primary to multiple amplitude response ratio greater than one.
