陆梁原油化学改性室内研究

Experimental Study on Chemical Modification of Luliang Crude

陆梁原油属含蜡高凝原油,混合样凝点达18C。通过对该地区原油进行化学改性试验结果表明,降凝剂GY-3、CE对陆梁原油有显著的降凝、降粘效果,加GY-3剂后降凝幅度可达18C,降粘率接近90％,低温流动性明显改善,且性能较为稳定。

Luliang crude belongs to waxy and high viscous crude oil,the set point of its mixed sample is 18 C. The experimental study on chemical modification of Luliang crude has shown that PPD GY-3 and CE are effective in modification, the set point of modified crude is respectively reduced to 18 C .10 C and 5 C . viscosity reduction rate is closed to 90%. low-temperature fluidity is greatly improved.
