摘要
为解决深部复杂地层常规钻井钻、测、固、完井各阶段漏喷复杂多、固井质量差、井控风险高等难题,在精细控压钻井技术基础上,发展形成了"钻—测—固—完井"全过程精细控压钻完井技术.本文详细介绍了国内外精细控压钻完井技术的研发、应用历程及发展现状,并剖析了该技术领域的发展趋势,即向个性化/系列化、集成化/融合化与数智化/智能化发展,逐步替代传统井控设备、走向智能井控技术;并给出了智能化发展的必经技术途径,为行业井筒压力控制技术发展提供参考.
Abstract
In order to solve the problems of frequent complications such as lost circulation,kick,poor cementing quality and high risk of well control during conventional drilling,logging,cementing and completion in deep com-plex formations,based on the managed pressure drilling technology,the whole-process managed pressure technolo-gy from drilling to completion has been developed.This paper introduces the development and application process and current situation of managed pressure drilling and completion technology at home and abroad.The develop-ment trend of this technology is analyzed,that is towards customization/serialization,integration/fusion and digiti-zation/intelligentization,which would gradually replace the traditional well control equipment and move towards intelligent well control technology.Finally the analysis of essential technical approaches for intelligent develop-ment are given,which can provide a reference for the development of wellbore pressure control technology.
