A processing method for Low S/N Seismic data in Loess Tableland in HJ area
Li Me · Progress in geophysics · 2014
HJ area belongs to the typical loess plateau in the south of Erdos Basin,which is always the hot region of Mesozoic oil exploration.But the seismic data quality is still restricted by the difficulties such as the complicated surface conditions,severe statics,much types of noises and low S/N ratio.Setting to study the key technology such as composite statics correction,the amplitude preserved denoising on prestack seismic data and common reflection surface stack,an processing idea to resolve the problem of low S/N step by step was summarized.Then the paper achieved optimum stack result.Seismic section realized the goal of palaeogeomorphology describtion.low amplitude structure identification and oil sandstone seismic prediction,which provides profitable support to the Mesozoic oil exploration.
