摘　　要：针对海上油田面临的油气开采技术难度大、重大技术迭代慢、大型作业技术应用成本高等多方面的挑战,中国海油经过数十年的发展,从稳产上产、技术迭代和降本增效等3方面推动技术变革,逐步形成了以“两提一降”为主线的数智化精细注水和稳油控水、大井距高强度稠油热采、低渗储层改造等三大工程技术,以及机采井延寿降耗、低产低效井增产、大修井作业、提高采收率等四类技术。提出了采油工程技术发展的10条技术路线,加快构建海上低成本采油工程技术体系,为推进中国海上油田采油工程技术高质量发展提供支撑。In view of challenges such as high technical difficulty in oil and gas production,slow pace of major technological iterations,and high application costs for large-scale operations in offshore oilfields,China National Offshore Oil Corporation(CNOOC)has promoted technological transformation from three aspects after decades of development:stable production,technological iteration,and cost reduction and efficiency enhancement.It has gradually formed three major engineering technologies with“enhanced oil recovery,well stimulation&control of decline rate”as the main line:digital and intelligent fine water injection and stable oil and water control,heavy oil thermal recovery with large well spacing and high intensity,and low-permeability reservoir transformation,as well as four types of technologies:life extension and power consumption reduction of oil recovery wells,production increase in low-yield and low-efficiency wells,major well maintenance operation,and enhanced oil recovery.CNOOC has also proposed ten technical routes for the development of oil production engineering technologies,accelerating the construction of a low-cost offshore oil production engineering technology system and providing support for the high-quality development of oil production engineering technologies of offshore oilfields in China.
