约束L_1模反褶积

Restrained L_1 modulo deconvolution

基于层状介质地震道褶积模型的L_1模反褶积方法，在单道处理中，由于各道集中占有强反射层的程度不同，反射系数位置的确定也不唯一，使得反褶积的结果破坏了剖面原有的连续性。本文通过采用位置约束条件的方法，不仅能找出主要反射层，而且位置基本准确，从而克服了原方法中因主要层位找得不准而造成的剖面横向连续性差的缺陷。理论模型与实际资料的处理结果表明，该方法是可行的。

In L1, modulo deconvolution based on seismic trace convolution model in layered medium, the deconvolution result usually loses the continuity of original seismic section because strong reflection horizons are exhibited in different degrees in different gathers and because their reflection coefficient locations can not be determined consistently in single trace processing. The application of location restriction condition causes the location of ma jor reflection horizons to be determined desirably, thus removing the original defect that seismic section shows poor continuity due to inaccurate location of major reflection horizons. Theoretical model and real data result prove the method feasible.
