远探测声波测井技术(亦称反射声波测井技术)能够从井中探测及评价井外数十米范围内的裂缝、洞穴和断层等地质异常反射体,大大拓展了测井技术的应用范围.在回顾该技术发展历程的同时,重点介绍了远探测声波测井处理解释核心方法、软件和现场应用效果.结合目前油田实际生产需求和现有技术面临的挑战,指出远探测声波测井处理解释方法有5个最重要的发展方向:继目前利用声波时差和密度通过反射系数褶积进行"测井约束下的地震反演"后,突破实现井下实测反射波和地面地震反射波正反演关系的直接建立,同时开展页岩储层裂缝成像、压裂效果评价、随钻地质导向研究及远探测声波测井仪器革新.
Development and prospect of acoustic reflection imaging logging processing and interpretation method
Acoustic reflection imaging logging technology can detect and evaluate the development of reflection anomalies,such as fractures,caves and faults,within a range of tens of meters from the wellbore,greatly expanding the application scope of well logging technology.This article reviews the development history of the technology and focuses on introducing key methods,software,and on-site applications of acoustic reflection imaging logging technology.Based on the analyses of major challenges faced by existing technologies,and in conjunction with the practical production requirements of oilfields,the further development directions of acoustic reflection imaging logging are proposed.Following the current approach that utilizes the reflection coefficients,derived from the computation of acoustic slowness and density,to perform seismic inversion constrained by well logging,the next frontier is to directly establish the forward and inverse relationships between the downhole measured reflection waves and the surface seismic reflection waves.It is essential to advance research in imaging of fractures within shale reservoirs,the assessment of hydraulic fracturing effectiveness,the study of geosteering while drilling,and the innovation in instruments of acoustic reflection imaging logging technology.
