流花油田二次开发的生产基础设施包括一座新的深水导管架平台“海基二号”和一座圆柱形FPSO装置“海葵一号”。

中海油表示，该项目将共计投入32口开发井，预计到2026年将达到约17,900桶油当量的峰值产量。

所产石油为重质原油，中海油对该项目拥有全部所有权和运营控制权。中海油首席执行官兼总裁周新怀表示：“这是亚洲首个采用‘深水导管架平台+圆柱型FPSO’模式开发的油田。公司克服了各种技术难题，完成了该项目。”

“新模式在盘活亿吨级深水油田的同时，大幅降低了建设和生产成本，为同类深水油气田高效开发提供了中国方案。”近日，中海油乌石23-5油田正式投产，这是南海地区首个采用岸电方式发电的油田。

乌石 23-5 油田开发包括两个新的井口平台和升级的乌石终端。该油田位于北部湾，平均水深约 28 米，预计到 2026 年将达到峰值产量约 18,100 桶油当量/天，石油类型为轻质原油。

上周，中海油宣布，其在珠江口盆地荔湾4-1构造成功钻探了一口井，在超深水天然气勘探方面取得了突破。该井位于深圳东南约300公里的白云凹陷，水深近1640米。该井的测试结果表明，绝对无阻流天然气产量为43万立方米/天。

CNOOC starts production from Liuhua 11-1/4-1 oilfield project

Oilfield Technology,

The project, which includes the Liuhua 11-1 and Liuhua 4-1 oilfields, is situated in an area with an average water depth of approximately 305 m in the eastern South China Sea.

The production infrastructure for the Liuhua oilfield secondary development comprises a new deepwater jacket platform, Haiji-2, and a cylindrical FPSO unit, Haikui-1.

CNOOC said the project is set to commission a total of 32 development wells and is expected to reach peak production of roughly 17 900 boe/d by 2026.

The oil produced is classified as heavy crude, and CNOOC holds full ownership and operational control of the project. CNOOC CEO and President Zhou Xinhuai said: “It is the first oilfield in Asia to be developed with the 'Deepwater Jacket Platform + Cylindrical FPSO' mode. The company has overcome various technological challenges to complete the project."

“While revitalising the deepwater oilfields with original oil in place over 100 million t, the new mode has substantially reduced the construction and production costs. It provides a Chinese solution for the efficient development of similar deepwater oil and gas fields.” Recently, CNOOC initiated production at the Wushi 23-5 oilfield, the first in the South China Sea to be powered from shore.

The Wushi 23-5 oilfield development includes two new wellhead platforms and the upgraded Wushi terminal. Located in the Beibu Gulf at an average water depth of around 28 m, the oilfield is anticipated to reach peak production of around 18 100 boe/d by 2026, with the oil being light crude.

Last week, CNOOC said it achieved a breakthrough in ultra-deepwater natural gas exploration by successfully drilling a well in the Liwan 4-1 structure within the Pearl River Mouth Basin. Positioned in the Baiyun Sag, roughly 300 km south-east of Shenzhen, the well reached a water depth of nearly 1640 m. The well's testing yielded an absolute open flow natural gas production rate of 430 000 m³ per day.
