摘要 随着压裂技术的不断进步和环境保护等相关法规的实施,低成本、可重复利用、绿色环保型压裂液技术必将成为今后压裂技术研究与应用的热点。文中分析了国内外水基压裂液重复使用技术研究与应用现状,按照压裂液增稠剂类型对现有技术进行分析归类,指出了目前技术存在的主要问题、开发难点和发展趋势。通过对现有技术现状的分析发现:目前重复使用的水基压裂液技术处在从返排液中"取水"制备压裂液的初级阶段,室内研究滞后于现场应用步伐,制约了新技术转化进程;新技术开发应兼顾返排液回收处理,避免相互脱节,影响新技术实际应用效果;新技术没有统一术语和评价标准,技术术语应用混乱,需制定统一行业标准,以便规范技术和推广应用。 With the continuous improvement of fracturing technology and the implementation of relevant laws and regulations such as environmental protection, low-cost, repeatable and green-type fracturing fluid technology is becoming the hotspot in the future research and application of fracturing technology. The status quo of the researches and applications of the domestic water-based fracturing fluid reuse was analyzed. According to the types of the fracturing fluid thickener, the existing technologies were analyzed and classified, and the main problems, development difficulties and development trends of the current technology were pointed out.Based on the analysis of the current state of the art, it is found that the current reused water-based fracturing fluid technology is in the initial stage of "withdrawing water" and then preparing fracturing fluid from the return fluid. The indoor research lags behind the field application and restricts new technology transformation process; new technology development should be taken into account the return fluid treatment to avoid disjunction with each other, affecting the practical application of new technologies; new technologies have no uniform terminology and evaluation criteria, causing the technical terminology confusion. The need to develop uniform industry standards for technical specifications and promotion is very urgent.
