Abstract:We have developed a deformable-layer tomography method with the joint use of first breaks and shallow reflections (Joint DLT) to calculate static corrections. The method is tested with a synthetic model and a field dataset from Tarim Basin,Western China. The synthetic test shows that our joint DLT method can provide velocity interface geometries with high resolution. The field test result indicates that the method can yield a geologically reasonable near-surface velocity model,and an improved stack section in comparison with the sections from the DLT (using only first breaks) as well as two other kinds of commercial tomostatics software.
