不同浓度烷基苯磺酸盐无碱三元复合体系界面及乳化规律
Interfacial activity and emulsification behavior of alkylbenzene sulfonate-based alkali-free ternary composite systems at different concentrations
为克服碱驱地层伤害与结垢,构建了烷基苯磺酸盐无碱三元复合驱体系。研究发现,其乳化稳定性由表面活性剂本征结构及界面吸附能力决定,与界面张力无关。正交实验表明,增黏能力影响主次为聚合物浓度>NaCl浓度>表面活性剂浓度;析水率影响为表面活性剂浓度>NaCl浓度>聚合物浓度。当表面活性剂质量分数为0.3%、NaCl质量分数为1.2%、聚合物质量浓度为1 800 mg/L时可实现超低界面张力、高乳化黏度及低析水率。岩心驱替证实,化学驱阶段采收率增幅30.14%,总采收率67.50%,优于石油磺酸盐弱碱体系。
To overcome formation damage and scaling caused by alkali flooding,an alkali-free ternary composite flooding system based on alkylbenzene sulfonate was developed.It was found that the emulsion stability is governed by the intrinsic structure of the surfactant and its interfacial adsorption ability,rather than by interfacial tension.Orthogonal experiments indicated that the order of influence on viscosity-enhancing ability is polymer concentration>NaCl concentration>surfactant concentration,while for water separation rate the order is surfactant concentration>NaCl concentration>polymer concentration.Ultra-low interfacial tension,high emulsion viscosity,and low water separation rate were achieved at a surfactant mass fraction of 0.3%,a NaCl mass fraction of 1.2% and polymer mass concentration of 1800 mg/L.Core flooding tests confirmed that the chemical flooding stage yielded an incremental oil recovery of 30.14% and a total recovery of 67.50%,outperforming the petroleum sulfonate weak-alkali system.
