摘要
为了推动老区油气田的进一步勘探开发,解决复杂隐秘油气储集体的勘探开发难题,主要针对单点高密度资料的处理方法进行研究。单点高密度资料的特点是小面元宽频带、宽方位、高炮道密度,同时信噪比较低,因此在室内资料处理过程中解决好信噪比问题非常关键,并基于地震资料的时频域特征利用分级曲波变换对叠前噪音进行组合压制。
In order to promote further exploration and development of oil and gasfields in the old area and solve the exploration and development difficulties of complex and hidden oil and gas reservoirs,this study focuses on the processing methods of single-sensor high-density seismic data.The characteristics of single-sensor high-density seismic data are small bin wide frequency band,wide azimuth,high shot density,and low signal-to-noise ratio.Therefore,it is crucial to solve the signal-to-noise ratio problem in indoor data processing.This study is mainly based on the time-frequency domain characteristics of seismic data,and utilizes graded curved wave transform to combine and suppress pre-stack noise.
