针对瓜胶压裂液成本大幅增加的问题，开展了替代瓜胶的新型压裂液体系研究。通过对改性黄原胶及高分子聚合物压裂液体系的综合性能评价，初步形成了一套改性黄原胶滑溜水和一套聚合物压裂液室内配方。目前，改性黄原胶压裂液还存在耐高温耐剪切性能差、破胶液残渣含量高的问题，聚合物压裂液存在稠化剂加量高、延迟交联性能与耐高温性能难以达到平衡的问题。新型压裂液体系进一步改进后可现场选井进行试验。

The studies of new fracturing fluid are carried out in order to take the place of guar gum due to increasing cost. Based on the comprehensive evaluation of fracturing fluid system of modified xanthan gum and high polymer, the laboratory recipes of fracturing fluid of modified xanthan gum slippery water and high polymer are proposed. The fracturing fluid of modified xanthan gum has some shortcomings such as poor resistance for high temperature and long-time shearing and high content of glue residue. The fracturing fluid of high polymer is in high content of thickener, and it is difficult to balance delayed cross-linking performance and high temperature performance. The new fracturing fluid system can be applied in field works after further improvement.
