【摘要】 碱法造纸黑液的主要成分是碱、碱木素和表面活性剂。在稠油开采中 ,利用碱法造纸黑液 ,可降低稠油的粘度。研究了用碱法造纸黑液代替热稀油降粘的可能性 ,复配了不同浓度的造纸黑液 ,并通过该黑液对辽河油田稠油乳化降粘的室内实验研究 ,证实了碱法造纸黑液对稠油有明显的降粘作用。在考察黑液对稠油降粘作用的基础上 ,同时探讨了不同造纸厂的黑液、黑液的质量分数及稠油和稀释液体积比对稠油乳化降粘效果的影响。实验结果表明 :在 50℃时 ,优先选用新宾造纸厂的黑液 ,将造纸黑液配成质量分数为 1 5%的稀释液 ,当油样与稀释液之比为V(油 ) :V(稀释液 ) =8:2时 ,可得到良好的降粘效果 ,从而提高原油的采收率 ,同时减少了造纸废液对环境的污染。更多还原

【Abstract】 Alkaline black liquor is composed of the alkali, alkali lignin and surfactant. It is capable of reducing viscosity in producing heavy oil .We study the possibility of reducing viscosity by using black liquor in place of hot dilute oil. It is proved that alkaline black liquor acts upon the reducing viscosity .The influence of the source and mass percentage concentration of black liquor ,the volume ratio of heavy oil and diluting solution on the reducing viscosity were investigated. All results show that the black liquor is efficient in reducing viscosity at 50 ℃ ,the concentration of diluting solution is 15% ,the volume ratio of oil and diluting solution is 8∶2 . The oil recovery is increased and the environmental pollution is decreased.更多还原
