摘要:阐述了清洁胶束压裂液延缓形成的机理,提出了胶束延缓形成的两种方法,并进行实验研究。结果表明,利用固体水杨酸微溶于水的性质以及尿素分解后所提供的弱碱性环境,能很好地延缓胶束形成;而在水杨酸钠的体系中加入尿素作为氢键阻断剂则在一定程度上可以降低压裂液的初始粘度。
Two mechanisms and methods for delayedformation of clear micelle fracturing fluids based on viscoelastic surfactants were described in detail and experimentally demonstrated. The two different mechanisms are: the delayed release of a specific counterion by using solid salicylic acid mixed with urea which can provide a temperature controlled alkalescent environment; and the controlled obstruction of hydrogen bonds by using urea in a system with sodium salicylate. The results show that the process of micelle delayedformation can be achieved by both methods if the amount of urea is appropriate.
