深埋在地层中的重质高粘高硫原油 ,占世界已探明石油储量的 6 0 %以上。若用常规 (压力 )方法来开采它们 ,不但困难 ,而且花费极大。因此 ,在采油和炼油中 ,利用微生物把重质原油分解成轻质低硫或不含硫的组分 ,以及脱除其他污染物质 ,不但经济实惠 ,而且还可净化环境。 Deeply buried in the formation of heavy high viscosity and high sulfur crude oil, accounting for more than 60% of the world’s proven oil reserves. If the conventional (pressure) method to extract them, not only difficult, but also costly. As a result, the use of microorganisms to break down heavy crude oil into light, low-sulfur or sulfur-free components, and the removal of other pollutants, is not only economical but also environmentally friendly in oil and oil refining.
