王庄稠油乳化降黏剂的筛选

针对胜利油田王庄稠油黏度大、开采难的问题,对其进行了降黏实验研究.首先测定了不同温度下王庄稠油的黏度.原油的黏温实验表明:王庄原油在温度超过60℃时,黏度随温度的升高变化趋缓.为王庄原油研制了降黏剂JDLH.影响降黏剂JDLH对王庄稠油降黏效果的因素有:降黏剂加量、油水比、降黏温度和矿化度等.实验结果表明:降黏剂JDLH最佳加入量为0.3%,最佳油水体积比为7∶3,降黏温度为50℃;降黏剂JDLH可耐盐15 000 mg/L.用5种不同的降黏剂对王庄稠油做了降黏实验,实验结果表明,降黏剂JDLH的降黏效果最好.

Sieving the emulsifying viscosity reducer for Wangzhuang high-viscosity oil of Shengli Oilfield

The emulsifying viscosity-reducing experiments of Wangzhuang heavy crude oil are performed.First,the viscosities of the heavy crude oil at different temperatures are measured.The result shows that the variation of the viscosity of the crude oil with temperature is quick when the temperature is lower than 60 ℃ and it becomes slow when the temperature is higher than 60 ℃.A emulsifying viscosity reducer JDLH is developed for Wangzhuang heavy crude oil.The factors of influencing the viscosity-reducing result of the viscosity reducer are experimentally studied,and it is shown that,the optimal dose of JDLH is 0.3%,the optimal ratio of oil to water is 7∶3,the reasonable heating temperature is 50 ℃,JDLH can bear the salt of 15 000 mg/L.Under the above conditions,the viscosityreducing results of 5 viscosity reducers are compared,and it is shown that the viscosity-reducing result of JDLH is the best.
