基于交互注意力分解融合的地震速度建模
Seismic Velocity Building Based on Interactive Attention DeMulti Unite
摘要
Abstract
The velocity parameter of seismic wave runs through the whole seismic exploration process and is very important for seismic imaging.Due to the low computational efficiency of traditional seismic velocity building methods,this paper proposes a seismic velocity building based on interaction attention DeMulti unite,namely IADMU model.Two parts of the network are pro-posed:DeMulti Unite Convolution(DMUC)and Interactive Attention Block(IAB).The original seismic shot record passes through the DMUC to extract its advanced feature information from the global and local dimensions.The deconvolution and inter-active attention modules are then fed to directly predict the corresponding velocity models with the help of cross-channel interac-tions.This paper conducts a lot of experiments on simulated data and SEG salt data sets,ablation experiment proves the effective-ness of the proposed DMUC and IAB;Comparative experiments demonstrated that,compared to U-Net,Res-UNet,and Deep-LabV3 networks,this network exhibited superior performance on both datasets,validating the superiority of the proposed net-work in this paper.关键词
