Research Progress and Prospect of Whole Process Managed Pressure Drilling and Completion Technology
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.
