原油

布伦特原油，WTI原油，墨西哥湾轻质低硫原油。

 

国际市场的原油主要是指，英国北海布伦特原油（BREN），美国的西德克萨斯轻质原油（WTI），以及墨西哥湾轻质低硫原油（LLS）。

相对而言，布伦特原油是一个有参考价值的综合性原油指数。一般来说，三者相对价格比较稳定，但是因为供需，地理等因素，有时会出现价格背离。比如说美国经济强劲是，布伦特可能会相对低一点儿。同时也就创造了套利的机会。

今后，由于美国国内的油气（尤其是页岩）产量逐步上升，对外依存度会下降，也就是价格下降的因素。当然，影响原油价格的因素很多，美元指数，经济景气度，量化宽松，战争，油田事故，等等。

 

 

West Texas Intermediate (WTI) crude oil is of very high quality and is at refining a larger portion of gasoline. Its API gravity is 39.6 degrees, which makes it a "light" crude oil, and it contains only about 0.24 percent of sulfur (making a "sweet" crude oil). 

 

Brent Blend is actually a combination of crude oil from fifteen different oil fields located in the North Sea. It is still a "light" crude oil, but not quite as "light" as WTI, and it contains about 0.37 percent of sulfur (making it a "sweet" crude oil, but again slightly less "sweet" than WTI). Brent blend is good for making gasoline and middle distillates.
