Pieces-linked pre-stack time migration strategies of low S/N ratio seismic data in North China

HAN Xiao-li1,QIN Hong-guo2, YANG Chang-chun1(1.Institute of Geology and Geophysics Chinese Academy of Sciences,Beijing 100029,China;2.GRI,BGP Inc.,CNPC,Zhuozhou 072751,China)  
Through the practical seismic data processing cases in North China,this paper analyzes characteristics of low signal to noise ratio seismic data in this region and the corresponding processing strategies.It also studies the matched techniques of pieces-linked pre-stack time migration processing in this area,and discusses how to improve migration imaging precision in seismic data processing.
