Effect of inaccurate wavelet phase on prestack waveform inversion被引量：2
《Applied Geophysics》2014年第4期479-488,511,共11页骆春妹 王尚旭 袁三一 
financially supported by the National Basic Research Program of China(973 Program)(No.2013CB228600);National Natural Science Foundation of China(No.41304108);Science Foundation of China University of Petroleum,Beijing(No.KYJJ2012-05-06);Science Foundation of China,University of Petroleum,Beijing(No.2462013YJRC007)
Wavelets are critical to inversion methods. Incorrect phase estimation will affect the objective function and cause convergence to local minima, and thus produce biased or incorrect results. Based on two simple models...
