塔里木盆地低信噪比地震资料处理方法研究

针对该区低信噪比资料的特点，曾在“九五”初期批处理软件平台上建立的低信噪比地震资料处理技术已难以适应勘探开发的需要。为此，2001年在交互处理软件平台上，充分利用灵活方便的交互手段及数据库管理方法，开发了一套较完善的低信噪比地震资料处理的技术，并在实际资料处理中取得了良好的效果。本文就解决该区低信噪比资料处理所采用的具体方法，以及所取得的初步成果做了简要介绍。该方法对复杂地表二维低信噪比地震资料的精细处理具有一定的借鉴意义。

Study on processing method for seismic data with low S/N ratio in Tarim basin.

All difficult factors,such as complicated surface and subsurface structure,complicated surface static correction and wavefield,difficulty of detecting useful signal and poor imaging quality resulted from complicated velocity field,etc.,bring a very difficulty to the seismic data processing in Bachu area,Tarim basin.In face of the characters of low S/N ratio data in this region,the processing procedure of seismic data with low S/N ratio built up in WGC batch software platform is difficult to meet the needs of exploration and development.So,in 1999 a set of perfect precessing methods for seismic data with low S/N ratio has been developed through the full use of flexible and convenient interactive tools of FOCUS processing software and management of data base in the platform of imported FOCUS interactive processing software,and achieved good results in application of real data processing.The paper briefly introduced the concrete processing techniques adopted in solving seismic data with low S/N ratio and the achieved preliminary results in order to make the processing level of seismic data with low S/N ratio in a condition of complicated surface get raise together.
