The fracturing fluid additive is optimized to provide a set of high quality and low damage fracturing fluid system for site construction. The main technical features are: selection of organic boron crosslinking agent, a new type of capsule breaker and high-quality demulsifier drainage agent to reduce the damage of fracturing fluid reservoir; the same time, the use of fracturing fluid optimization technology for fracturing fluid optimization. The results of laboratory evaluation and field experiments show that the optimized fracturing fluid formulation has good comprehensive properties, good temperature and shear resistance, low fluid loss, low surface tension and low damage, and can meet reservoir and reservoir conditions Fracturing process requirements. In the field of fracturing 6 wells, the yield is good.
