通过分析现场和室内试验结果,研究了不同条件下高速剪切后加剂原油低温流动性的恢复问题。研究表明,加剂原油低温流动性的恢复与原油的组成和高速剪切后的温度条件有关。有的加剂原油高速剪切后恶化了的流动性可以恢复,有的不能恢复,还有的原油根本就不受影响。加剂原油的恢复性与温度有关,在高温下剪切后流动性可以恢复的原油在低温下不一定能恢复。 Through the analysis of field and laboratory test results, the recovery of low temperature fluidity of the crude oil added after high-speed shearing under different conditions was studied. The research shows that the recovery of low temperature fluidity of additive crude oil is related to the composition of crude oil and the temperature conditions after high speed shearing. Some additives crude oil deteriorated after high-speed shear fluidity can be restored, and some can not be restored, as well as crude oil is not affected at all. The recovery of additive crude oil is related to temperature. Crude oil with fluidity can be recovered after shearing at high temperature may not be able to recover at low temperature.
