Discussion on Current Situation and Development Trend of Drilling Equipment for Deep and Ultra-deep Wells
In order to facilitate the efficient exploration and development of deep and ultra-deep oil and gas re-sources in China,the challenges posed by deep and ultra-deep wells to drilling equipment are analyzed in this pa-per.The functions and characteristics of seven types of products,including automatic drilling rigs,pipe automa-tion equipment,energy storage,conservation and management,driller integrated control system,intelligent deci-sion and support platform,etc.,from Nabors,Schlumberger and NOV,are discussed.The development and ap-plication situation of domestic pipe automatic drilling rig,one-click man-machine interactive 7,000 m automatic drilling rig,12,000 m automatic drilling rig,pipe automation equipment,storage,conservation and management,driller integrated control system,drilling assistant decision and support system and so on are analyzed.Through benchmark analyse,it is concluded that China's oil drilling equipment has made great progress,but there are still many shortcomings in terms of engineering demand and application and a big gap compared with foreign advanced technology.It is recommended that domestic equipment manufacturers comply with the national"carbon peak,carbon neutral"goal and the trend of digital transformation and intelligent development,and carry out key techni-cal research from the aspects of improving parameter,rig automation,intelligent operation and maintenance of e-quipment,driller operation on duty and greener drilling operation.
