FLNG/FLPG工程模式及其经济性评价

大型浮式液化天然气FLNG(Floating Liquid Natural Gas)船/浮式液化石油气FLPG(Floating Liquid Pe-troleum Gas)船是近年来海洋工程界提出的、主要用于深远海气田开发的工程装置,是集海上天然气液化、储存和装卸为一体的新型装置,具有开采周期短、开采灵活、可独立开发、可回收和可运移、无需管道输送等特点,有可能是开发我国南海深远海气田重要的工程应用模式之一。为此,以南海某深水气田作为目标气田,对比分析了传统的开发工程模式与FLNG/FLPG开发工程模式的经济性,结果表明,采用该装置开发深水天然气田可节省投资。同时还分析了不同离岸距离对投资的影响,结论认为,使用该装置对离岸距离不敏感。因此,FLNG/FLPG开发工程模式对离岸距离较远的深远海气田具有较好的经济性,是一种值得推广的深远油气田开发工程模式。

踔厉奋发 笃行不怠

律回春渐,新元肇启。时序更替,华章日新。天道酬勤,力耕不欺。2021年,我们感受了日新月异的发展,壮大了赓续传承的事业,看到了一个坚韧不拔、欣欣向荣的中国。在科技赛道上,“天问一号”携“祝融号”成功登陆火星,我国第一个1500米水深自营深水天然气田“深海一号”正式投产,中国空间站首位女航天员王亚平登临太空舒展巾帼风采。在经济主战场,党中央沉着应对百年变局和世纪疫情,有力抵御经济运行面临的需求收缩、供给冲击、预期转弱三重压力,有效破解发展中的困境和难题,实现进入新发展阶段的稳健开局,继续保持经济发展和疫情防控的全球领先地位……多少看似不可改变的体制壁垒、多少看似不可突破的认知和能力极限,因为敢于破壁、敢于创造,再坚硬的天花板也挡不住一个时代的穿透。

Deepwater oil and gas field development in South China Sea

This paper focuses on potential development models of future oil and gas exploration in South China Sea. A detailed study of current development models worldwide is performed through some examples of industry installed/ongoing projects and major technical issues encountered during these practice. Key technologies are discussed for the success of field development. Some of the technologies and field development experience can be used for South China Sea project. Several models are studied in field development for different scenarios,including marginal field,large oil field and gas field. With the massive investment activities,continued improved technologies,and rapidly growing pool of professionals,the offshore industry in China will soon encounter a golden period.
