摘要
以先进的通信网络为依托的更为精细化、智能化的数字油田将成为未来的发展趋势。为了提高分层注水的精度与效率,基于数字油田的发展,引入传感器技术、自动化技术和信息化等技术,研制了海上平台注水井远程控制与管理系统。系统由井下部分、海上平台部分以及陆地基地部分组成,采用直流电力线载波通信方式,实现对多口井、多个层注水的集中、高效、精细化管理;同时,系统异常情况报警保护功能实现了地层超压报警和井口压力超压报警,并能实现水嘴的自动关断功能,保证了注水安全。现场应用结果表明:地面控制设备与井下智能测调工作筒通信正常,在地面可以实现井下注入量的监控与调配,分层调配配注量和注入压力达到配注要求。该系统的研制为数字化油田的发展奠定了基础。
More elaborate and intelligent digital oilfield based on advanced communications network will be the future trend. For the digital oil field development,the sensor technology,automation technology and information technology have been introduced to develop the remote control and management system for offshore water injection well. The developed system consists of the underground components,offshore platform components and land base components. DC power line carrier communication was used to achieve centralized,efficient and fine management of multiple wells and layers. The system＇s abnormality alarm protection allows for formation and wellhead overpressure alarm,and enables automatic shutdown of nozzle to ensure water injection safety. Field application results showed that the ground control device and downhole intelligent testing and adjustment working string have good communication. Water injection volume could be monitored and regulated on the ground. The water injection pressure had met the requirement of injection allocation. The developed system had laid the foundation for the development of the digital oilfield.
