Hydraulic fracturing, as an oil-water well stimulation and injection technology, is particularly important in the production and stimulation of low-permeability oil and gas fields, and the performance of the fracturing fluid directly affects the success of the fracturing operation. Compared with traditional water-based fracturing fluids, clean fracturing fluids have the advantages of strong sand-carrying ability and easy gel breaking with no residue. Aiming at the problem of poor temperature resistance and shear resistance of the clean fracturing fluid, based on previous research, this paper selects a high-temperature-resistant clean fracturing fluid system and evaluates the performance of the system. The research results show that the system has better rheological properties, better sand-carrying performance, shorter gel-breaking time, and less damage to the reservoir.
水力压裂作为一种油水井增产增注技术，在低渗透油气田的开采和增产中具有十分重要的作用，压裂液的性能直接影响压裂施工的成败。与传统的水基压裂液相比，清洁压裂液具有携砂能力强、破胶无残渣等优点。针对清洁压裂液耐温抗剪切性能差的问题，本文在前人研究的基础上，优选出一种耐高温清洁压裂液体系，并对该体系的性能进行评价。研究结果表明，该体系具有更好的流变性、携砂性能更好、破胶时间更短、对储层伤害更小。
