Technical Research on Key Equipment for Offshore Ultra-high Temperature and High-pressure Oil and Gas Well Drilling
This paper presents a brief introduction on main offshore ultra-high temperature and high-pressure well drilling equipment,and analyzes the current status,key technologies and research and development ideas of these equipment.The results show that,among the key equipment for ultra-high temperature and high-pressure well drilling,blowout preventer and control system,wellhead device,mudline suspension device and downhole tools should be improved preferentially through researches.There is a gap between China and other countries in the design,manufacturing and testing of these key equipment,mainly reflected in four key technologies:development of high-strength metal materials,design and manufacturing of seals,development of control component and sea trial of system equipment.Moreover,detailed research and development ideas were proposed for these key technolo-gies,with the aim of promoting the localization process of key equipment for ultra-high temperature and high pres-sure well drilling,and enhancing the exploration and development capabilities of offshore ultra-high temperature and high-pressure oil and gas fields in China.
