Progress and Trends of Digital Well Control Technology
With the oil and gas exploration and development towards complicated fields such as high tempera-ture,high pressure,deep water and deep formation,the difficulty of drilling and completion,as well as the risk of well control,continues to increase.With the deep integration of digital technology and well control technology,digital well control technology has played a prominent role in well control risk identification,kick emergency re-sponse,and well control emergency response,helping to improve the level of well control risk management and the efficiency of emergency response.This article summarizes the current research status of digital well control technology both domestically and internationally.It introduces the technical status and application effects from seven aspects:well control information management system,intelligent well control training system,managed pres-sure drilling,intelligent early kick detection,automatic shut-in and killing,intelligent emergency equipment,and digital twin well control technology.Additionally,it analyzes the development gap between domestic and foreign digital well control technology.Finally,based on the existing digital well control technology,the key research di-rections and development trends for primary,secondary,and tertiary well control are proposed for peer reference.
