相干体技术在揭示地层的横向变化及断层和复杂构造等方面与常规的地震振幅切片相比具有很大的优越性。但当原始振幅数据体信噪比较低时,相干体受噪声干扰较大,分辨率较差。为克服常规相干体计算受噪声影响较大的缺点,通过引入保边去噪技术,提出一种基于三维保边去噪(3DEPS)的相干体分析方法,在进行相干分析之前,先对原始振幅数据体做三维保边去噪,实际资料的计算结果显示,利用该方法得到的相干切片对断层和复杂构造的分辨能力得到显著提高。
Coherent body technology has great advantages compared with conventional seismic amplitude slicing in revealing the lateral variation of strata and the faults and complicated structures. However, when the SNR of the original amplitude data body is low, the coherent body is greatly disturbed by noise and the resolution is poor. In order to overcome the shortcomings that the conventional coherence body calculation is greatly affected by noise, a coherent body analysis method based on three-dimensional edge preserving denoising (3DEPS) is proposed by introducing the edge-preserving denoising technique. Before the coherence analysis, the original amplitude Data body to do 3D Pauling denoising, the actual data of the calculated results show that the use of the method of coherent slice of the fault and complex structure resolution was significantly improved.
