Abstract

In order to overcome the disadvantages in the conventional prestack seismic data splicing processing , the post stack record was used to obtain shaping operators. Then the shaping matched filtering is perormed. This technique makes the seismic data with different characteristics consistent on frequency , phase and mplitude ,and carries out the prestack seismic data splicing. The practical application of the technique showed that it could provide high quality prestack gathers for subsequent processing , by which the shaping operators obtained are stable and easy to perform , and that it is assuredly a good choice for block-tie processing.

Key words： extra-low permeability; surface density; micro-fracture; Ordos Basin
