| 摘 要： | 海底电缆（OBC）采集方式的出现，导致OBC采集与拖缆采集数据进行拼接成为三维连片地震资料处理中的一个重要环节.由于采集方式不同，数据在振幅、频率、相位等方面均存在较大差异.为了消除和减小这些差异，为后续的地质解释和油气预测提供便利，本文提出了一种在子波域的1范数匹配滤波方法来计算匹配滤波因子，以用来提高OBC数据和拖缆数据的匹配精度，改善连片处理的数据品质，为后续的地质解释和油气预测提供便利.通过实际资料检验，子波域匹配滤波方法在OBC与拖缆数据拼接应用中取得了较好的效果.

| Abstract: | With the emergence of OBC (Ocean-Bottom Cable) the combination of OBC and cable acquisition data becomes a key step in large 3D seismic data joint processing. Because of different acquisition methods, there is a lot of differences in the amplitude, phase, and frequency of OBC and cable data. In order to eliminate these differences and get a good result for geological interpretation and hydrocarbon prediction, in this paper we present a wavelet domain L1-norm minimization matching filter method to improve OBC and cable data's matching precision, enhance the combination quality and facilitate the geological interpretation and hydrocarbon prediction. According to real data test, the wavelet domain matching filter for OBC and cable seismic data combination obtained good results. |
