本發(fā)明提供一種混疊噪聲壓制方法及裝置,其中,該方法包括以下步驟:將混疊的共炮點(diǎn)域數(shù)據(jù)轉(zhuǎn)換為共偏移距域混疊數(shù)據(jù);對(duì)共偏移距域混疊數(shù)據(jù)進(jìn)行混疊噪聲壓制;若壓制混疊噪聲后的共偏移距域混疊數(shù)據(jù)的信噪比小于預(yù)設(shè)值,則對(duì)所述壓制混疊噪聲后的共偏移距域混疊數(shù)據(jù)進(jìn)行混疊計(jì)算,得到混疊數(shù)據(jù),將所述混疊的共炮點(diǎn)域數(shù)據(jù)更新為所述混疊數(shù)據(jù),重復(fù)執(zhí)行以上步驟,直到壓制混疊噪聲后的共偏移距域混疊數(shù)據(jù)的信噪比大于等于預(yù)設(shè)值;將信噪比大于等于預(yù)設(shè)值的壓制混疊噪聲后的共偏移距域混疊數(shù)據(jù),轉(zhuǎn)換為壓制混疊噪聲后的共炮點(diǎn)域數(shù)據(jù)。本發(fā)明實(shí)現(xiàn)了對(duì)混疊的共炮點(diǎn)域數(shù)據(jù)中混疊噪聲的壓制,提高了地震數(shù)據(jù)的信噪比,提升了混疊噪聲壓制效果。
