Hyper-branched fracturing fluid system is mainly composed of gelling agent, crosslinker, gel breaker and activator. During the synthesis of gelling agent, products, functional monomers are introduced to adapt to different types of site water in various regions. At the same time, hydrophobic monomers are also introduced, especially branched chain agent is introduced to change the linear molecular structure into branched molecular structure to achieve high temperature-resistance and shear-resistance function.
Hyperbranched fracturing fluid system avoids the disadvantages of guar gum fracturing sysem of high damage to reservoir, high friction and low shear resistance. At the same time, it also has the characteristics of clean and low residue and easy flowback.Suitable for low,medium and high temperature reservoir.
