In view of characteristics of seismic data of gobi - sand dune areas, this paper, through various data - processing means such as quality control, high - pass filltering, dip angle filltering, field static correction, surface consistency deconvolution, precise velocity analysis, denoising before stack, multiple iterative operation of residual static correction, denoising after stack and modification after shift, has raised the data quality of seismic profiles in low signal - to - noise ratio areas and managed to form the seismic data - processing technique for such complex areas as gobi, foreland and dune
摘要針對戈壁、沙丘地區地震資料的特點，通過對原始資料進行質量控制、高通濾波、傾角濾波、野外靜校正、地表一致性反褶積、精細速度分析、疊前去噪、剩餘靜校正多次迭代、疊後去噪和偏後修飾等處理，提高了低信噪比地區地震剖面的資料質量，摸索出了一套戈壁、山前、沙丘等復雜地區地震資料處理技術。 -
Further, analyse the characteristic of the seismic wavefield of fractural reservoir and the influence caused by fracture density, property of the filled material and the strike of fracture. fifthly, in term of research of zhangshulun et al., concisely discuss the arithmetic of the plane wave forward modeling and migration with phase shift method, in prestack common offset gathers and check the arithmetic by numerical simulation
第四，用基於彈性?聲學近似的反射系數計算公式和本文提出的付氏變換子波生成法得到縫洞模型的反射系數模型和子波模型並用vrselrf波場延拓運算元對其進行地震波場數值模擬；進一步分析了縫洞儲層的地震波場特徵及縫洞密度、充填物性質和裂縫走向對其波場特徵的影響。
