摘　　要：胜利滩浅海油田位于海陆交汇处,以埕岛油田、新北油田为典型代表,具有油藏类型多样、地面条件复杂、海工配套投资大的特点,效益开发难。立足胜利滩浅海油田开发实践,重点梳理了“十一五”以来技术成果,经过持续技术攻关,形成了以滩浅海油田细分加密综合调整、滩浅海油田整体注采调控、海油陆采高效开发、滩浅海边际油藏有效动用、复杂裂缝性潜山油藏开发为核心的胜利特色滩浅海油田高效开发技术,建成国内首个400万吨级滩浅海油田——埕岛油田,实现了从陆上到海上的跨越。通过剖析滩浅海油田目前高质量发展面临的问题,明确了在新区效益建产与老区提高采收率技术支撑上面临的挑战。作为胜利油田持续上产的重要阵地,针对未来滩浅海油田面临的上产需求与未动用储量品位低以及老区稳产基础与液量受限两大挑战,提出了滩浅海油田“少井高产、高速高效”的发展方向,即持续攻关滩浅海复式油气藏效益动用、基于平台集约化的“3+2”开发方式下的二次井网重构、基于大模型的智能注采调控等关键技术,支撑胜利滩浅海油田高质量持续发展。Shengli beach-shallow sea oilfields are located at the junction of sea and land,with Chengdao Oilfield and Xinbei Oil-field as representatives.They have the characteristics of diverse reservoir types,complex ground conditions,and significant invest-ments in ocean engineering facilities,so it is difficult to develop beneficially.Based on the development practice of the Shengli beach-shallow sea oilfield,this paper focused on the technical achievements since the“11th Five-Year Plan.”The efficient develop-ment technologies for characteristic Shengli beach-shallow sea oilfields were formed through continuous technical research,with the cores of subdivision and comprehensive adjustment of beach-shallow sea oilfields,overall injection and production regulation of beach-shallow sea oilfields,efficient development of offshore oil production,effective utilization of beach-shallow sea marginal oil-field,and development of complex fractured buried hill oil reservoir.The first beach-shallow sea oilfield of four million tons,Chengdao Oilfield,was built in China,realizing the crossing from land to sea.The challenges in the efficient production construc-tion in the new area and the technical support of enhanced oil recovery in the mature area were clarified by analyzing the problems facing the high-quality development of the beach-shallow sea oilfield.By considering the important position for the continuous pro-duction of Shengli Oilfield,the development direction of“fewer wells,high yield,high speed,and high efficiency”was proposed to alleviate the contradiction between the production demand and low grade of unproduced reserves,as well as the stable production foundation and restrictive liquid production in the mature area faced by the beach-shallow sea oilfield in the future.In other words,it is necessary to continue to study critical technologies,such as the beneficial utilization of multiple oil and gas reservoirs in beach-shallow sea,the reconstruction of secondary well pattern under the“3+2”development mode ba
