摘要
约束稀疏脉冲反演包括测井和地震资料预处理、合成记录标定、建立初始波阻抗约束模型、选择反演参数以及频谱补偿等关键环节。以胜利油田C工区为例,该区储层砂砾岩体的横向变化大、尖灭点位置不明、测井资料分布不均。经约束稀疏脉冲反演得到的反演剖面上,横向上砂砾岩体的尖灭点反映清晰,纵向上波阻抗变化与测井岩性解释剖面吻合。
Constrained sparse spike inversion include the following key points：logs and seismic data＇s preprocession, synthetic seismogram, building initial constrained impedance model, choosing right and Spectraldomain interpolation . In Che66 area,glutinite reservoir varies laterally and the wells are bad-distributed. Through constrained sparse spike inversion,glutinite＇s pinchout reflects clearly in seismic section, and the impedance＇s variation fits the logs＇ lithological characteristic.
