海上油田智能井技术发展应用及探讨

海上油田进入开发中后期，注采调整难度加大，如何有效动用低深稠等边际储量已成为亟待解决的技术难题。目前，国外智能井技术已经成功应用了二十余年，而中国智能井驱油技术从引进跟跑已步入了跨越发展的最佳阶段。针对中国海上油田增储上产的客观需要与智能井升级的发展现状，开展了国内外智能井技术理论及矿场应用的综述研究，并依据陆相沉积的开发特点和生产难点，分析了当前中国海上智能井技术跨越式发展的制约因素，探讨了智能井技术发展的目标方向与潜在途径。研究表明，海上智能井技术与数字油田联合升级的潜力巨大，国内关键的技术突破已为系统性升级奠定了扎实基础。智能井技术的低成本发展，对推动海上油田增储上产具有重要意义。

A Discussion on the Development of Intelligent Well Technology in Offshore Oilfield

As offshore oilfields gradually enter the middle and late stages of development, it is more difficult to adjust injection and production. How to effectively use such difficult and marginal reserves has become an urgent technical problem. At present, the overseas intelligent well technology has been successfully applied for more than 20 years, while China's intelligent well displacement technology has just stepped into the best stage of leapforg development stage. Aiming at the needs of increasing production in offshore oilfield and the status of upgrading intelligent well, this paper reviews the theory and application of intelligent well technology at home and abroad. According to the development features and difficulties of continental sedimentary oilfield, the authors analyze the restriction in the leapfrog development of intelligent well technology in China offshore, and discuss the target direction and potential paths of the upgrading intelligent well technology. The studies have shown that it is of great potential for joint upgrading of intelligent well technology and digital oilfields. The breakthrough of technology has laid a solid foundation for systematic upgrade. The low-cost application of intelligent well technology has the great significance to increase the storage and production in offshore oilfield.
