摘要

在苏丹3/7区块的地震资料处理压制多次波过程中，过去存在压制多次波不足或者损伤有效信号的问题，这些问题可用分级多域迭代组合去噪技术解决:①根据多次波的周期性先用预测反褶积压制近偏移距的周期性多次波；②用Radon变换分别在炮域、检波点域和CMP域压制远偏移距的多次波；③在CRP道集上用高精度Radon变换压制剩余的多次波。通过应用上述技术，很好地压制了研究区块较发育的多次波，从而使处理成果品质有了较大改善，获得了多次波压制好、信噪比高的地震资料，为总结该区块潜山地区油气成藏规律，识别油气聚集带提供了可靠资料。

Abstract

In Sudan 3/7 block,when we do seismic data processing,especially the processing of multiple,it is suppressed.There are some problems.For example,the multiple cannot be suppressed completely,or some of the primary reflection energy is lost.These problems can be solved by iteration combination technology in multiple domains step by step:(1)According to the periodicity of multiple,we use predictive deconvolution to suppress near offset multiple firstly.(2)Using Radon transform in shot-gather domain,detection domain and CMP domain respectively to suppress the multiple of far offset.(3)Finally,we use high precision Radon transform to suppress the residual multiple in CRP gather.Through the application of the technology,we suppressed the multiple in this block very well,the seismic data quality has been improved,and we obtained high S/N ratio seismic data,so we provide credible seismic data for the research of the oil gas distribution pattern and identification of oil and gas accumulation zone.
