文本描述
《油气开采与钻探培训课程课件》(72页).rar 油气开采与钻探 Exploring and Drilling for Oil and Gas 什么是石油,什么是天然气? 石油和天然气是储存在地层中的物质 它们是从分解的动植物残骸演变而来 科学家们认为石油是这样形成的: 很久很久以前死亡的动植物被厚厚的沉积物缓慢掩埋。经过很长的时间,在一定的压力和温度下,这些有机物转变成立今天人们发现的石油。 (例如:我们现在知道堆积的垃圾可以产生沼气) What are Oil and Gas? Oil and Gas are substances found within the earth's crust. They are thought to come from decomposed plant and animal matter. Scientists believe the plants and animals died long ago, and were slowly buried by thick layers of sediments.  Over a long period of time, and with pressure and temperature, the organic materials were converted into the oil and gas which are found today.  (For example, we know that present day garbage dumps give off methane gas) 关于油气我们还需要知道些什么? 自然状态下的石油有的粘稠,有的稀薄。颜色有黑的,也有浅颜色的。 很多其他材料也来自于石油产品: 塑料 织布的材料 (例如: 聚酯纤维) 日用化学品  各种油漆 What else do we know about oil and gas? Oil in it's natural state can be thick or thin,  black or light colored. When oil is refined, many products can be obtained: Energy for power Gasoline for cars Diesel fuel for trucks and trains Hi-octane fuels for planes Heating oil for houses Many other materials also come from petroleum: Plastics Materials for clothes (example: polyester fabrics) Chemicals for everyday use  Paints,,,,,,,,,
