摘要
鄂尔多斯盆地黄土塬地区地震地质条件复杂,造成原始地震资料信噪比及分辨率较低,同时煤层气目的层埋深很浅,对地震勘探精度要求也较高。针对黄土塬地区原始地震资料的特点,在较好解决静校正、去噪等问题的基础上,应用共偏移距域上的地表一致性反褶积、反Q滤波等处理技术提高了地震资料的分辨率。
The complexity of the seismic-geologic conditions in loess tableland of Ordos Basin is caused by low signal/noise and low resolution of the initial seismic data,besides the target stratum of CBM is shallow,and the demand of exploration accuracy is high.The features of loess tableland,the practical high-resolution processing methods are presented in this paper.It includes applying common offset deconvolution,inverse Q filter and so on.The higher resolution of the seismic data is obtained on the basis of good applicable effects in static correction and noise suppression.
