国内外主要油(气)田水中锂提取现状及展望

油(气)田中常伴生油(气)田水,与自然界其他水体相比常具有较高的锂含量,部分可达工业品位。我国油(气)田水储量大,锂资源量可观,但在过去却长期被忽视。近年来,在盐湖卤水型液体锂资源提取技术不断取得突破的大背景下,卤水型锂资源产量占比逐年升高,油(气)田水型锂资源也应当受到重视。本文通过研究大量国内外主要油(气)田中伴生的油(气)田水锂含量及分布特征,归纳国内外油(气)田水提锂技术现状,为我国油(气)田水中锂的综合利用提供参考。

我国油(气)田水钾资源研究进展

我国是一个拥有13亿人口的农业大国,但是钾盐资源紧缺,多年来对外依存度高达50%以上。在地表盐湖增储潜力有限、海相地层找钾尚未取得突破性进展的情况下,富钾油(气)田水成为解决我国钾资源燃眉之急的首选。近年来,国内在"油钾兼探"方针的指导下对富钾油(气)田水进行了大量勘探、调查评价和研究工作并取得了丰硕的成果。从卤水特点、卤水地球化学和资源评价3个方面总结了前人对柴达木盆地、四川盆地、江汉盆地、塔里木盆地等重要钾盐前景区油(气)田水的研究成果,得出了我国不同盆地油(气)田水资源特点,评价了各盆地油(气)田水研究现状,认为应该重点加强对柴达木盆地西部地区的油(气)田水找钾及研究工作,而且各盆地在油(气)田水资源评价方面研究薄弱,亟需建立油(气)田水资源评价标准与方法。

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.
