| 摘 要： | 针对辽河油区复杂构造区地震资料介质速度横向变化快和信噪比低的特点,开展了基于波动方程理论的炮域保幅叠前深度偏移技术和共反射面元(CRS)技术研究。并将这2项新技术应用于辽河断陷复杂构造区低信噪比地震资料成像,实际应用取得了较好的处理效果,为辽河油田小断块、微幅度复杂构造和深层、凹陷两侧油气勘探地质研究提供了可靠的依据。

| Abstract: | The seismic data of complex structures in Liaohe oilfield is characterized by fast lateral change of media velocity and low signal-to-noise ratio. Based on wave equation theory, preserved amplitude prestack depth migration within shot domain and bin (CRS) techniques have been studied. These 2 new techniques have been used for imaging seismic data of low signal-to-noise ratio in complex structures of Liaohe depression and have obtained good processing result, thus providing reliable basis for geological study in oil and gas exploration in small fault blocks, mini-amplitude complex structure, deep formation, and depression flanks in Liaohe oilfield. |
