流花油田是我国首个深水油田,位于珠江口盆地。项目通过“海基二号”与“海葵一号”协同作业,实现了深水油田的二次开发。
这个国庆假期,我国深水油田产油量再获新突破。今天,我国首个深水油田——流花油田二次开发项目累计生产原油突破200万吨。截至目前,油田已生产原油超过4000万吨,日产量达到了投产22年来的新高,为保障国家能源安全提供了坚实保障。
国之重器“海基二号”“海葵一号”协同运转
流花油田二次开发项目位于珠江口盆地海域,作业平均水深305米,依托亚洲第一深水导管架平台“海基二号”、亚洲首艘圆筒型海上油气加工厂“海葵一号”以及水下生产系统协同作业。这两座海上形态各异的“国之重器”如何安全高效协同运转?流花油田交出了一份深水大型设施运维的“中国方案”。
“海葵一号”“海基二号”依次排布,分别承担生产处理、储油外输、钻井采油功能,依托海陆一体化智能中控系统,将240多公里外的现场作业纳入深圳陆地生产操控中心统一监控。
中国海油流花油田“海基二号”总监 舒正勇:针对南海台风多发,夏季内波流频发的特点,团队为两座设施配套“台风模式生产”功能,依靠远程操控保持稳定生产。该智能化管理模式已应用11次,挽回产量损失超5万吨,创造经济效益超1.7亿元。
设施健康运维同样全面数字化。“海基二号”导管架集成数字孪生系统、海洋环境监测系统和海底环境监测系统,实时感知结构应力与海床变化,实现了深水大型设施从“人防”到“智防”的转变。
中国海油流花油田“海葵一号”FPSO外输监督 薛廷:“海葵一号”面对海域内频发的内波流,配备了专用内波流监测系统,以及雷达监测、守护船巡查等多维手段,实时监测系泊张力与提油轮船位状态,实现风险提前预判、隐患快速处置,全年外输作业窗口期利用率达90%以上。
深远海能源运输体系保障原油高效外运
开发深水油田,既要有把原油安全采出来的能力,也要有把它高效运出去的保障。中国海油正加快构建自主可控的深远海能源运输体系,逐步打通深水油气外输自主链路,为保障国家能源安全提供坚实支撑。
流花油田是我国首个深水油田,在此服役的亚洲首艘圆筒型浮式生产储卸油装置——“海葵一号”没有常规船型浮式生产储卸油装置的风标效应,姿态调整空间有限,原油外输面临巨大挑战。
中海油国贸北海船务公司“北海开拓”轮船船长 陈景明:新造专用船舶周期长、投入成本高,我们对现有油轮“北海开拓”实施专项改造,首次在国内常规油轮上加装艏装载系统,仅用12天完成坞内施工,较计划提前1个月完成测试交付。
改造后的“北海开拓”轮,单次最大可运输45万桶原油。截至目前,已累计完成52船次提油作业,运输原油超200万吨。在船舶硬件适配的同时,中国海油搭建油气外输智能运行平台,为提油时机研判、靠泊计划优化、外输资源协同配置及特殊气象海况应对提供数智化保障。
海油发展销售服务公司副总经理 杨双玮:智能运行平台运用AI+大数据技术,智能匹配100余艘外输船舶,目前已覆盖20个外输终端,全年发送1600余次船舶调度指令,为海上原油安全高效外输提供了有力支撑。
The International Gas Union (IGU) Council 2026 and the 'Empowering a Sustainable Future' Summit will take place in Hong Kong from 26 to 29 October. Hosted by Towngas, the event will convene global experts to discuss energy security, AI, and green finance.

The International Energy Agency warns that Southeast Asia faces mounting energy security risks as rising demand for electricity outpaces regional solutions, exacerbated by global conflicts and the need to power expanding digital infrastructure.
As of October 5, the Malda Hydropower Station, the highest hydropower station in the main stream of the Yellow River, has accumulated power generation of more than 5 billion kilowatt-hours during the year, a year-on-year increase of approximately 21.51%, setting a new high for the same period in history. As the backbone power point of the "West-to-East Power Transmission", the power station continues to contribute to the transformation of green energy.

During the National Day holiday, Guo Feng, a well control Sichuan and Chongqing project technician of Daqing Drilling Directional Well Branch, was on duty in the Luzhou Southwest well control workshop. He urgently inspected and delivered a set of internal blowout prevention tools to ensure the safety of underground production, reflecting the dedication of oil workers to stick to their posts and ensure energy supply during the holiday.
China's first offshore carbon injection and gas enhancement technology demonstration application project - the main body of the new central platform of the Dongfang 1-1 gas field has been completed in Qingdao and has fully entered the commissioning stage. After the project is put into operation, it can store more than 1 million tons of carbon dioxide in the seabed strata every year, helping China build an offshore CCUS base.
