油田伴生气具有非常高的经济效益,特指与石油共生于同一处的天然气,基于有机成烃生油理论,伴生气通常是由有机质演化而来,石油为液态烃,伴生气便是气态烃,由于同一物质的气态质量远远低于其液态质量,因此伴生气通常位于油气藏的顶部,其主要成分为甲烷、乙烷,并有少量的丙烷、丁烷或戊烷,均是对环境有严重污染的清洁能源,若不回收损失较大。本文试对这些油田伴生气进行研究与分析,探究其回收装置现状。
The associated gas in oilfield is of very high economic benefit, especially natural gas coexisting with petroleum. Based on the theory of organic hydrocarbon generation and production, associated gas is usually evolved from organic matter, petroleum is liquid hydrocarbon, and associated gas is gaseous hydrocarbon Since the same material has a much lower gaseous mass than its liquid mass, the associated gas is usually located at the top of the reservoir, with its main components being methane, ethane and a small amount of propane, butane or pentane, There are serious pollution of clean energy, if not loss recovery. This paper attempts to study and analyze associated gas in these fields and explore the status quo of their recovery units.
