利用油泥制备油煤水浆的实验研究 --

油田生产中的副产物油泥具有高粘度和含油的特性,为了合理、有效地利用这些副产物,考虑将油泥和传统的水煤浆进行混合。实验发现:加入等量分散剂的情况下,聚羧酸系分散剂和自制分散剂对油泥的分散效果较好,油泥的流动性得到改善。当向油煤水浆加入20%～25%的降粘油泥时,浆体粘度小于1000 mPa.s,随着温度升高,浆体粘度逐渐降低,剪切变稀特性良好,制备出的油煤水浆能够较长时间放置而不分层,具有良好的稳定性。 The plastocene has the character of high viscosity and oleiferous,which is the by-product of oil production.In order to effectively and efficiently utilize the plastocene,provide a method,which is mixing plastocene with traditional coal water slurry.The experimental datas show that when the additive number of dispersing agents are equal,polycarboxylic acid type and self-made dispersing agents have better effect,the fluidity of plastocene has been improved.When the percentage of slurry added to the coal-oil-water slurry ranges from 20% to 25%,the viscosity is less than 1000 mPa·s,which gradually descends with the rise of temperature.The shear thinning character is getting better.This kind of coal-oil-water slurry also has good rheological property and stability.It doesn't delaminate for a long time
