摘　　要：本文针对金刚石绳索取心钻进过程中钻杆内壁结垢影响岩心顺利打捞的问题,在借鉴国内外研究成果的基础上,系统梳理了影响钻杆内壁结垢的主要因素,编制了可以方便、快捷地计算结垢指数I和临界通径D_(c)的计算程序系统,系统可根据计算结果提出相应的防垢除垢措施。在工程中进行了现场应用,为现场钻探工程师进行防垢除垢、确保钻探安全高效进行提供了有益的科学指导。This article focuses on the problem of scaling on the inner wall of the drill pipe during the diamond wire-line coring drilling process,which affects the smooth salvage of the core.Based on the research results at home and abroad,the main factors affecting the scaling on the inner wall of the drill pipe are systematically sorted out,and a calculation program that can conveniently and quickly calculate the scaling index I and critical diameter D_(c)is developed.It has been applied on site in scientific drilling projects,providing useful scientific guidance for on-site drilling engineers to prevent scaling and ensure safe and efficient drilling.
