Problems solved by technology

[0002] Slick water and fracturing fluid materials are important technical liquids or materials for oil and gas stimulation, especially in shale oil and gas development. Most of the existing slick water or fracturing fluids are polymers or vegetable gums, and their molecular weight The high or molecular structure is fixed, and the effect is realized by adding the natural properties, and there is also a lack of a regulatory system that realizes the overall coordination of molecular groups, chains, molecular structures, components, and intermolecular mechanics. Structural performance can be coordinated and coordinated as a whole. The control system reflects the liquid viscosity, structure, gel breaking, dissolution, sand carrying, rent reduction, and drainage as a whole. The drag reduction and viscosity increase materials that appear in the change are composed of a structural system and lack of replanting and drag reduction. Preparation method of tackifying material

[0003] In addition, due to the lack of functional materials for regulating ions in the liquid in the existing materials, the performance of the functions in the field of chemical materials and the achievement and control of precise performance are restricted. Especially in the field of fracturing fluids, the water quality of the existing fracturing fluids cannot be refined. The liquid performance cannot be accurately realized through simple and rough existing masking methods

[0004] Existing fracturing proppants are not easy to carry, require high performance fracturing fluid, easy to remove plugs during construction, and the effect of increasing production after reaching the predetermined position is not good

[0005] The above problems seriously restrict the development of oil and gas energy. At the same time, the lack of relevant materials with specific characteristics and precise realization of functions seriously hinders the refinement and in-depth development of water treatment, printing and dyeing, food, medicine and hygiene.
