压裂技术是提高低渗透油气藏生产能力和油气井采收率的重要手段,而压裂液是影响压裂效果的关键因素。相较于水基植物胶压裂液和以单链表面活性剂为稠化剂的传统清洁压裂液,双子表面活性剂类清洁压裂液在耐温、携砂和保护油气层等使用性能上更具优势,是新一代清洁压裂液发展重点。本文综述了双子表面活性剂类清洁压裂液制备、性能及应用的研究进展,分析比较了阳离子双子表面活性剂类清洁压裂液、阴离子双子表面活性剂类清洁压裂液、两性双子表面活性剂类清洁压裂液等的优缺点,讨论了双子表面活性剂类清洁压裂液在油田领域的应用现状:阳离子双子表面活性剂类清洁压裂液的制备方法成熟,耐温性能较好,可以应用于中高温油田,但是其生产成本较高;阴离子双子表面活性剂类清洁压裂液能有效减少表面活性剂在地层的吸附损失,降低储层渗透率伤害,但是其合成条件苛刻,耐温性不高,适用于中低温油田;两性双子表面活性剂类清洁压裂溶液的耐温性好,但是其制备过程繁琐、成本高,难以大规模推广应用。对双子表面活性剂类清洁压裂液的研究前景进行了展望:发展低成本的合成方法及耐高温双子表面活性剂类清洁压裂液的制备及应用。 相似文献

Anionic and cationic surfactant mixtures exhibit desirable synergism, but are limited by their tendency to form precipitates. This research evaluates the adsorption, adsolubilization and desorption of mixtures of carboxylate-based anionic extended surfactants and a pyridinium-based cationic surfactant. The mixture of cetylpyridinium chloride (CPC), selected as the cationic surfactant, with four anionic extended surfactants were studied. The anionic surfactants studied were alkyl propoxylated ethoxylated carboxylate with average number of carbon chain length of 16 and 17 or 16 and 18 with 4?mol of propylene oxide groups and either 2 or 5?mol of ethylene oxide groups. The adsorption of anionic extended and cationic surfactant mixtures onto a negatively charged metal oxide surface (silica dioxide) was evaluated. The adsolubilization of phenylethanol, styrene and ethylcyclohexane were evaluated for these mixed surfactant systems. The desorption potential of individual and mixed surfactant systems was also evaluated by varying the number of washing (desorption) steps. It was found that the plateau adsorption of mixed anionic extended surfactant and cationic surfactant occurred at lower surfactant concentration than that of the CPC alone, although the maximum adsorption capacity of CPC was not enhanced in our mixed surfactant systems. Adsolubilization capacities of these mixed surfactant systems are higher than that of the individual surfactant system. For desorption studies, these mixed surfactant systems showed lower stability than the individual surfactant system. 相似文献

The micellar, adsorption, and adsolubilization properties of a novel ethoxy carboxylate extended surfactant are measured and
compared to an extended sulfate surfactant. The critical micelle concentration (CMC) of the ethoxy carboxylate extended surfactant
is measured to be 0.02 mM while it is 0.07 mM for the extended sulfate surfactant. Adsorption and adsolubilization studies
are carried out on alumina oxide surfaces. The extended sulfate surfactant has a higher maximum adsorption capacity onto the
aluminum than the ethoxy carboxylate extended surfactant (0.47 vs. 0.14 mmol/g, respectively). For adsolubilization, the extended
sulfate surfactant shows a slightly higher phenanthrene adsolubilization compared to the ethoxy carboxylate extended surfactant
(log Kadm of 6.15 vs. 5.71, respectively). In contrast, for solubilization, the ethoxy carboxylate extended surfactant exhibits higher
phenanthrene solubilization capacities than the extended sulfate surfactant (log Kmic of 5.61 vs. 5.42, respectively). Relative to surfactant loss from the solid surface, the ethoxy carboxylate extended surfactant
shows a higher desorption capacity as compared to the extended sulfate surfactant. From these measurements, the ethoxy carboxylate
extended surfactant has better properties for micellar applications (lower CMC, higher Kmic), while the extended sulfate surfactant has better properties for admicellar applications (higher qmax and Kadm values, and less desorption). 相似文献
