摘要
利用微生物在油田中进行清防蜡是近几年来发展的一门新技术,微生物可以有效地清除管道中的蜡沉积,对油田生产具有很大的经济效益。阐述了管道结蜡机理;分析了影响管道结蜡的影响因素;介绍了国内外几种常用的清防蜡技术,如机械清蜡技术、热力清蜡技术、化学清蜡技术等;讨论了几种清防蜡技术的优缺点及适用性。基于此,着重对微生物清防蜡技术进行了综述,对石油行业的清蜡、防蜡技术研究、提高油田生产效率,有一定的指导意义。
It is a new technology developed in recent years to use microorganism to remove wax deposits in oil fields.In this paper,the mechanism of pipe waxing was described.The influencing factors of pipeline waxing were analyzed.Several commonly used wax removal techniques at home and abroad were introduced,such as mechanical paraffin removal,thermal paraffin removal and chemical paraffin removal techniques.The advantages,disadvantages and applicability of several wax removal techniques were discussed.Based on this,the technology of microorganism paraffin removal and paraffin prevention was summarized.The paper is of guiding significance to the study of paraffin removal and paraffin prevention in the petroleum industry and the improvement of oil field production efficiency.
