Diffraction separation by plane-wave prediction filtering被引量：6
《Applied Geophysics》2017年第3期399-405,461,共8页孔雪 王德营 李振春 张瑞香 胡秋媛 
funded jointly by the National Natural Science Foundation of China(No.41104069);the National Key Basic Research Program of China(973 Program:2011CB202402);the Shandong University Science and Technology Planning Project(No.J17KA197);the College of Petroleum Engineering in Shengli College China University of Petroleum"Chunhui Project"(No.KY2015003)
Seismic data processing typically deals with seismic wave reflections and neglects wave diffraction that affect the resolution. As a general rule, wave diffractions are treated as noise in seismic data processing. How...

Preconditioned prestack plane-wave least squares reverse time migration with singular spectrum constraint
《Applied Geophysics》2017年第1期73-86,190,共15页李闯 黄建平 李振春 王蓉蓉

Prestack Gaussian beam depth migration under complex surface conditions被引量：11
《Applied Geophysics》2010年第2期143-148,194,共7页岳玉波 李振春 张平 周学锋 秦宁 
supported by the National 863 Program of China(Grant No.2007AA060502);the National 973 Program of China(Grant No.2007CB209605);the Graduate Student Innovation Fund of China University of Petroleum(EastChina)(Grant No.S2010-1).
In areas with a complex surface,the acquisition and processing of seismic data is a great challenge.Although elevation-static corrections can be used to eliminate the influences of topography,the distortions of seismi...

Amplitude.preserving plane-wave prestack time migration for AVO analysis被引量：1
《Applied Geophysics》2008年第3期212-218,共7页王棣 程玖兵 郑晓东 王华忠 马在田 
To support amplitude variation with offset （AVO） analysis in complex structure areas, we introduce an amplitude-preserving plane-wave prestack time migration approach based on the double-square-root wave equation in...
