随着低渗、致密砂岩和页岩油气的大规模开发，水力压裂技术将被广泛运用，与此同时水资源消耗问题日益突出。油田产出水、压裂返排水和海水基压裂液的运用将极大缓解这一矛盾。笔者分析了高浓度矿物离子对常规压裂液体系性能的影响机理，系统总结和分析了近20年高矿化度水基压裂液体系的性能特点和应用情况，展望了高矿化度水基压裂液体系的研究方向和发展前景。参35

With large scale exploitation of low-permeability oil and gas，tight sand oil and gas and shale gas，hydraulic fracturing technology will be widely applied，meanwhile，water Consumption is increasingly outstanding. However，the application of produced water，flowing-back water and seawater based fracturing fluids will ease such contradiction. In the paper，The impact mechanism of high-TDS salt to conventional guar-based borate-crosslinked fracturing fluids was analyzed ，and the performances and applications of the most high-TDS water based fracturing fluids applied in the past 20 years were summarized. In the end，the research direction and development prospect of high-TDS-water based fracturing fluids were forecasted.
