摘　　要：为了提高油气开采效率,油田在勘探开发过程中,越来越多地需要同时实现井周成像和前视成像。当前随钻井下成像仪在测量时存在着一定的盲区,影响成像效果,且需要多次起下钻来实现井周成像和前视成像,影响了效率。因此,文章调研了随钻声波井周成像和前视成像技术的发展现状,探讨了融合随钻声波井周成像和前视成像的井下全景成像技术。在此基础上,分析了目前随钻声波井周成像和前视成像所面临的挑战,提出了从测量盲区的突破、声电复合、井周—前视融合、数字孪生可视化四个角度来实现随钻声波井下全景成像技术的升级,为切实推进随钻井下成像系统的可视化和智能化提供参考和借鉴。In order to improve the efficiency of oil and gas exploration and production,more and more oil fields need to achieve both borehole imaging and forward-looking imaging during the exploration and development process.However,there are still some blind spots in the current downhole imaging system while drilling,which affects the imaging effect.Moreover,it requires multiple trips to achieve borehole imaging and forward-looking imaging,which affects efficiency.Therefore,this paper investigates the current research status of acoustic borehole imaging and forward-looking imaging while drilling,and explores the downhole panoramic imaging technology that integrates while drilling acoustic borehole imaging and forward-looking imaging.On this basis,the challenges from the current development of acoustic borehole imaging and forward-looking imaging while drilling are analyzed,and then four perspectives,including breakthrough in measurement blind spots,the combination acoustic signal and electric signal,the fusion of borehole imaging and forward-looking imaging,and digital twin visualization are proposed,to achieve the upgrade of downhole acoustic panoramic imaging technology while drilling,which will provide reference for effectively promoting the visualization and intelligentization of downhole imaging systems while drilling.
