A deep learning framework for suppressing prestack seismic random noise without noise-free labels
《Energy Geoscience》2024年第3期261-274,共14页Han Wang Jie Zhang 
employed by Petroleum Exploration and Production Research Institute of SINOPEC;funded by the National Key R&D Program of China(2021YFC3000701).
Random noise attenuation is significant in seismic data processing.Supervised deep learning-based denoising methods have been widely developed and applied in recent years.In practice,it is often time-consuming and lab...

3D model of Svecofennian Accretionary Orogen and Karelia Craton based on geology,reflection seismics,magnetotellurics and density modelling:Geodynamic speculations
《Geoscience Frontiers》2020年第3期999-1023,共25页Michael V.Mints Victor N.Glaznev Olga M.Muravina Elena Yu Sokolova 
the RF state project(No.0135-2019-0036);partly supported by the project(No.0135-20180039)of the Program of the Presidium of the RAS“Fundamental problems of geological and geophysical study of lithospheric processes”;the Russian Foundation for Basic Research for supporting project(No.19-05-00336)。
A 3D model of deep crustal structure of the Archaean Karelia Craton and late Palaeoproterozoic Svecofennian Accretionary Orogen including the boundary zone is presented.The model is based on the combination of data fr...

Imaging disturbance zones ahead of a tunnel by elastic full-waveform inversion:Adjoint gradient based inversion vs.parameter space reduction using a level-set method被引量：1
《Underground Space》2018年第1期21-33,共13页Andre Lamert Luan T.Nguyen Wolfgang Friederich Tamara Nestorovic 
We present and compare twoflexible and effective methodologies to predict disturbance zones ahead of underground tunnels by using elastic full-waveform inversion.One methodology uses a linearized,iterative approach bas...

Robust adaptive polarization analysis method for eliminating ground roll in 3C land seismics被引量：3
《Applied Geophysics》2013年第3期295-304,358,共11页陈海峰 李向阳 钱忠平 赵桂玲 
supported by the National Natural Science Foundation of China(No.41074080);the Important National Science&Technology Specific Projects(No.2011ZX05019-008)
To improve the data quality of converted waves, and better identify and suppress the strong ground-roll interference in three-component （3C） seismic recordings on land, we present an adaptive polarization filtering ...
