摘要
通过对长6和长8油藏脱气原油、溶气原油的物性及流变性进行实验研究,分别从压力条件下原油溶气稀释效应、含蜡原油热处理效应、非牛顿含蜡原油的剪切历史效应等方面,对长庆油田原油不加热集输技术的流变学原理进行了系统的阐释,也为更好地指导长庆油田矿场集输系统的优化设计与经济、安全运行提供理论支持。
Based on the physical property and rheological experiments of degassing and live crude oil from Chang 6 and Chang 8 oilreservoirs,the rheological principle of unheated crude oilgathering and transportation in Changqing Oilfield is systematically expounded in aspects of crude oil dissolved gas dilution effect,waxy crude oil heat treatment effect,non- Newtonian waxy crude oil shear history effect,etc.under the pressure condition.And the oretical support for better guiding optimization design and economical and safe operation of Changqing Oilfield gathering and transportation system is provided.
