摘　　要：以北疆原油为研究对象,进行室内降凝剂筛选实验,确定了最优的加剂量为50×10^(-6),最优加剂温度为55℃。并对北疆加剂原油进行管输模拟,得到在实际的输送过程中,管流剪切对加剂原油的影响,实验和模拟表明,剪切作用能使凝点降低2~10℃。当凝点降低到一定程度后,剪切作用又使凝点有所回升。Taking the crude oil as the research object to make the screening experiment of pour point depressant,and to make sure that the optimal dosage is 50＆#215;10-6 and the optimal additive temperature is 55℃.The effect of pipeline flow shear on the oil in the process of actual delivery is obtained through the oil simulation.The experiment and the simulation shows that Shearing action can make 2℃ to 10℃ pour point reduction.When the pour point is reduced to a certain extent,the shear effect makes the point rebound.
