【摘要】 为了解决直接用水洗油砂洗油效率低的问题,进行了复配化学剂油砂热洗室内实验,考察了NaOH和Na2CO3及其复配溶液,XY系列洗油剂复配对内蒙古图牧吉地区一井油砂洗脱率的影响,根据油砂洗脱率指标,优选适合该地区油砂的最佳复配化学剂。结果表明,在洗油剂与油砂质量比为1∶1,恒温85℃,加热60min时,NaOH与Na2CO3复配溶液的洗脱率高于单一碱液的洗脱率,洗油剂体系XY-1和XY-2与碱复配时,优选的洗油剂配方为NaOH(1.0%)+Na2CO3(1.0%)+XY-1(0.15%)和NaOH(1.0%)+Na2CO3(1.5%)+XY-2(0.10%)。更多还原

【Abstract】 The combinational chemical agent washing experiment was carried out in order to solve the problem of low oil sand elution efficiency by using water. The affection of NaOH, Na2CO3 , combinational chemical agent and XY series agent on elution ratio of oil sand of inner Mongolia Tumidi area was studied. The optimization combinational chemical agent was selected according to the oil sand elution ratio. The experiment result shows that in the experimental condition of agent with the oil sand quality ratio is 1∶1, the constant temperature 85 ℃ and heats up for 60 min, elution ratio of NaOH and Na2CO3 combinational chemical agent is better than single lye, when XY-1 and XY-2 combustion with alkali, the optimization prescription is NaOH(1.0%)+Na2CO3(1.0%)+XY-1(0.15%) and NaOH(1.0%)+Na2CO3(1.5%)+XY-2(0.10%).更多还原
