川东南地区存在着大量的灰岩出露区,灰岩出露区由于波阻抗界面不明显,地震激发能量衰减快,下传困难,深层反射能量较弱,单炮资料品质总体上较差,信噪比低,此次处理的主要目的就是提高信噪比。本文使用了叠前去噪技术、优化迭代叠加技术和叠后去噪等技术,使得地震资料的信噪比和分辨率得到了改善和提高。 There are a large number of limestone outcropping areas in the southeastern Sichuan area. Because the interface of wave impedance is not obvious, the seismic excitation energy decays rapidly, the descent is difficult, the reflection energy in the deep layer is weak, the quality of the single shot is generally poor, The ratio of low, the main purpose of this treatment is to improve the signal to noise ratio. In this paper, pre-stack de-noising, optimized iterative overlay and post-stack de-noising are used to improve the signal-to-noise ratio and resolution of seismic data.
