摘　　要：通过系统回顾中国石油海外油气田开发技术的发展历程,总结已形成的特色开发技术,并针对海外油气开发面临的挑战,提出未来海外业务的发展目标与技术发展方向。中国石油经历海外20多年的油气田开发实践,将国内成熟油气田开发技术与海外油气藏特征相结合,形成了以海外砂岩油田高速开发及稳油控水技术、大型碳酸盐岩油气藏高效开发和超重油油藏整体水平井泡沫油冷采开发技术为代表的海外特色开发技术。在深入分析海外油气开发面临的挑战和技术需求的基础上,结合国内外油气开发技术发展趋势,提出未来海外油气开发技术需重点研发人工智能储集层预测与三维地质建模、海外砂岩油田高速开发后二次开发及提高采收率、海外碳酸盐岩油气藏注水注气提高采收率、海外非常规油气经济有效开发、海域深水油气藏高效开发配套技术等,实现海外高含水砂岩油田提高采收率技术继续保持国际领先,碳酸盐岩油气藏开发技术达到国际先进,非常规和海域深水油气开发技术逐步缩小差距,实现快速追赶等目标。This study reviews the development history of PetroChina’s overseas oil and gas field development technologies, summarizes the characteristic technologies developed, and puts forward the development goals and technological development directions of overseas business to overcome the challenges met in overseas oil and gas production. In the course of Petro China’s overseas oil and gas field production practice of more than 20 years, a series of characteristic technologies suitable for overseas oil and gas fields have been created by combining the domestic mature oil and gas field production technologies with the features of overseas oil and gas reservoirs, represented by the technology for high-speed development and stabilizing oil production and controlling water rise for overseas sandstone oilfields, high efficiency development technology for large carbonate oil and gas reservoirs and foamy oil depletion development technology in use of horizontal wells for extra-heavy oil reservoirs. Based on in-depth analysis of the challenges faced by overseas oil and gas development and technological requirements, combined with the development trends of oil and gas development technologies in China and abroad, overseas oil and gas development technologies in the future are put forward, including artificial intelligence reservoir prediction and 3D geological modeling, secondary development and enhanced oil recovery(EOR) of overseas sandstone oilfields after high speed development, water and gas injection to improve oil recovery in overseas carbonate oil and gas reservoirs, economic and effective development of overseas unconventional oil and gas reservoirs, efficient development of marine deep-water oil and gas reservoirs. The following goals are expected to be achieved: keep the enhanced oil recovery(EOR) technology for high water-cut sandstone oilfield at international advanced level, and make the development technology for carbonate oil and gas reservoirs reach the international advanced level, and the development techn
