The product is a water-based cross-linking agent for fracturing fluid used for oil well of 40 ~ 130℃ and prepared from galactose-mannan. It is characteristic of wide application temperature, good resistance to high temperature and shearing, easy gel-break, and delaying of cross-linking. The main ingredient is organic boron compound, with similar cross-linking principle as borax.
