【摘要】：為了充分利用地震記錄中的繞射波信息刻畫地下小尺度構(gòu)造(斷層、尖滅、裂縫、鹽丘側(cè)翼等),本文在高斯束偏移過程中,借助傾角掃描及運(yùn)動(dòng)學(xué)與動(dòng)力學(xué)射線追蹤方法,構(gòu)建反穩(wěn)相濾波算子,發(fā)展了一種基于反穩(wěn)相策略的深度域繞射波分離成像方法。在編程實(shí)現(xiàn)算法的基礎(chǔ)上,通過國際標(biāo)準(zhǔn)的Sigsbee 2A模型驗(yàn)證了本文方法的正確性。同時(shí),利用實(shí)際資料繞射波分離成像測試,驗(yàn)證了方法對陸上實(shí)際資料具有較好的適用性。
[Abstract]:In order to make full use of the diffraction wave information in seismic records to depict small scale underground structures (faults, pinches, fractures, flanks of salt dome, etc.), in the process of Gao Si beam migration, dip scanning and kinematic and dynamic ray tracing methods are used in this paper. An inverse phase filter operator is constructed and a depth domain diffractive wave separation imaging method based on the inverse phase stabilization strategy is developed. On the basis of programming algorithm, the correctness of this method is verified by the international standard Sigsbee 2A model. At the same time, the application of the method to the real land data is verified by using the diffraction wave separation imaging test of the actual data.
