全球石油项目现在主要以酸油为对象,由于轻甜油不断减少而造成重质原油,这增加了提炼和环境挑战。 Global oil projects now mostly target sour, heavy crude due to dwindling light sweet oil, raising refining and environmental challenges.

全球新的石油项目越来越侧重于酸、重或两种类型的原油,估计大约90%属于这些类别。 New oil projects globally are increasingly focused on sour, heavy, or both types of crude, with estimates suggesting around 90% fall into these categories. 这一转变反映出对传统浅质甜质原油的利用越来越少,日益依赖更复杂、更昂贵的采掘方法。 This shift reflects declining access to conventional light sweet crude and growing reliance on more complex, costly extraction methods. 这一趋势突显了在完善基础设施和解决环境问题方面的挑战,因为酸油和重油需要更多的加工和产生更高的排放量。 The trend underscores challenges in refining infrastructure and environmental concerns, as sour and heavy oils require more processing and produce higher emissions.
