摘　　要：随着越来越多的海上油田开发面临高含水率、高采出程度,在生产油田调整挖潜难度大,新探明的潜山、稠油、低渗储量占比逐渐升高,油田储量劣质化,建设中国海油油气资源供给保障中心面临着钻完井技术、钻完井成本及外部环境的多重挑战。针对存在的主要问题,近年来中国海油构建了基于“井型优选、科学完井、精细控制”为核心的“少井高产”钻完井技术理念,创新发展并形成了“井型优化、产量提高、长效稳产、剩油挖潜”4个方面的钻完井技术系列和10项关键技术,建立了针对不同油气藏类型的“少井高产”钻完井技术体系,并取得了良好的应用效果。展望了“少井高产”钻完井技术未来重点研究方向。中国海油“少井高产”钻完井技术体系的形成可为海上油气田高效开发提供借鉴意义。As more and more offshore oilfields face high water cut and high recovery degree,it is difficult to adjust potential tapping in production fields.In addition,the proportions of newly discovered buried hills,heavy oil,and low permeability reserves are gradually increasing,and the oilfield reserves are becoming inferior.The construction of CNOOC oil and gas resource supply security center faces multiple challenges from drilling and completion technology,drilling and completion cost,and external environment.In view of the main problems,in recent years,CNOOC has established a technical concept of“high production with fewer wells”based on the core of“well type optimization,scientific completion,and fine control”and has innovated and developed a series of drilling and completion technologies and ten key technologies in four aspects:“well type optimization,production improvement,long-term stable production,and potential tapping of remaining oil”.The technical logic of“high production with fewer wells”for different types of oil and gas reservoirs has been established,and good application results have been achieved.Finally,the paper provides an outlook on the key research directions and development of drilling and completion technology for high production with fewer wells.The formation of CNOOC drilling and completion technology system of high production with fewer wells has reference value for the efficient development of offshore oil and gas fields.
