Sand-free fracturing fluid with high flow conductivity as well as preparation method, fracturing technology and application of sand-free fracturing fluid

The invention relates to sand-free fracturing fluid with high flow conductivity as well as a preparation method, a fracturing technology and application of the sand-free fracturing fluid. The sand-free fracturing fluid comprises a group-A fracturing fluid containing a curable resin prepolymer and a group-B fracturing fluid containing a curing agent and fibers, wherein the group-A fracturing fluidand the group-B fracturing fluid are used cooperatively. The fracturing fluid prepared by the preparation method disclosed by the invention can enter all levels of fractures to form fiber enhanced porous resin to ensure that a fractured complicated fracture net system is relatively high in flow conductivity and can support the fractures, so that the oil and gas recovery rate is increased. Furthermore, the fracturing technology disclosed by the invention is simple, and the fracturing risk is reduced. 本发明涉及种具有高导流能力的无砂压裂液、其制备方法及压裂工艺与应用。该无砂压裂液包括含有可固化树脂预聚体的A组压裂液和含有固化剂和纤维的B组压裂液，所述A组压裂液和B组压裂液配合使用。本发明制备的压裂液可以进入到各级裂缝中形成纤维加强多孔树
