新疆油田红浅火驱试验区原油物性变化规律研究

Research Crude Oil Variable Rule by Fire Flooding in Xinjiang Hongqian Oilfield

试验区历经4年多燃烧,地下原油性质发生较大程度的变化。为进一步认识火驱特性、指导生产调控,对原油组分、黏度、酸值、非金属元素、金属元素等变化规律进行了研究。研究结果表明,试验区原油经过火驱以后,改质作用明显,轻质组分质量分数上升、黏度明显下降;原油中金属与非金属元素出现明显变化。

The fire flooding has lasted 4 years,crude oil properties has happened a certain degree of chang obviously underground. For further understanding of fire flooding characteristics,directing production and regulation,for studying the characteristics of crude oil,such as composition,viscosity,acid value,nonmetallic elements,metallic elements,etc. The results showed that,reservoir was developed by fire flooding,modification effect is obvious,light component quality score rise,viscosity is decreased obviously; mental and nonmental elements have been a significant change.
