This paper presents the results of investigating the destructive and oil - displacing capacities of species w3 , g12 and s11 for waxy crude oil from production well chang 74 : reduction of wax content by 7 - 11 % and of interfacial tension by 10 . 7 44 . 0 % ； reduction of high carbon number normal alkanes and enrichment of low carbon number ones ; production of gases ( mainly co2 and n2 ) and acids ; enhancement in oil recovery by 8 . 2 10 . 6 % ( in core experiments ) 本文报道这几种菌在油藏条件下的生长情况，与昌74井原油的作用及岩心驱油结果：使原油含蜡量降低7 % 11 % ，使界面张力降低10 . 7 % 44 . 0 % ，使高碳数正构烷烃含量下降，低碳数正构烷烃含量增多，产酸产气，提高岩心采收率8 . 2 % 10 . 6 % 。
The anion surfactant nals was the most efficient in the process and was selected as collector by orthogonal method . the interfacial tension and cmc of nals ( cmc 6 . 5 10 - 3m ) in the solution was measured by hanging ring test , the function relationship between interfacial tensions and nals concentration was : = - 0 . 9523 in 2c - 24 . 534 in c - 81 . 411 . the relation of interfacial adsorption equilibrium in the solution system was respectively tested and calculated with gibbs equation and dynamic method . the conclusion showed that ( 1 ) the experiment result of dynamic method with was highly in coordination with the value which from theoretical calculation . ( 2 ) the surfactant molecule was in arrangement of monomolecular layer at the gas - liquid interface 用吊环法测定了十二烷基硫酸钠水溶液不同浓度与其界面张力的关系，拟合得到的回归方程为= - 0 . 9523ln ~ 2c - 24 . 534lnc - 81 . 411 ，同时还测得其临界胶束浓度值( cmc为6 . 5 10 ~ ( - 3 ) m ) ，运用吉布斯等温方程和动态法分别计算和测定了该溶液系统的界面吸附平衡关系，结论表明： ( 1 )动态法测定结果基本吻合吉布斯方程的理论计算； ( 2 )表面活性剂分子在气?液两相界面是以单分子层形式定向有序排列的。
The effects of demulsifiers on interfacial tensions and membrane strength were studied for the model and effluence systems from the three - compound - combination flooding field . the interfacial tensions owned by the two - compound - combination system decreased but those owned by the three - compound - combination system increased with increasing the demulsifier concentrations . membrane strength decreased with the increase of demulsifier . the demulsification mechanism of demulsifier is suggested that demulsifier partially replaces the stabilizers and greatly decreases the intensity of interfacial film 针对模拟采出液和三元复合驱矿场采出液,研究了破乳剂对复合体系界面张力和膜强度的影响.破乳剂浓度增加,二元复合体系界面张力降低,而三元复合体系界面张力升高.破乳剂分子部分顶替乳化剂分子并显著降低了界面膜强度
The development of mass transfer in the system of vapor - liquid - liquid three - phase distillation from trays was introduced , the effects of the hydrodynamic conditions e . g . vapor velocity and ratio of liquid to vapor loading and physical properties of liquid phase , including surface tension , interfacial tension , viscosity or dispersion viscosity , density , relative volatility etc . and the volume ratio of oil to water on mass transfer were discussed systematically , the influence of the second liquid on mass transfer efficiency was also investigated , a gnat deal of viewpoints and suggestions having been put forward in this paper are significant important for optimizing design of distillation tower 摘要介绍了气液液三相精馏塔板传质性能研究的进展情况，讨论了气速、液气比等操作条件，表面张力、界面张力、液体的粘度或分散粘度、密度和相对挥发度等物系性质以及油水体积比等多种参数对传质效率的影响，探讨了第二液相的存在对传质的影响，文中的许多观点获和建议对于优化精馏塔的设计具有重要的指导意义。
