‍Centrealoil‍‍--Ultra-low concentrations of guar gum crosslinker

Product introduction:

This product is made up of boric acid and a variety of ligand under certain reaction conditions, to produce a highly efficient organic boron complex, It can crosslinks with guar gum and its derivatives to produce gel cross-linking.

It can decrease the concentration of Hydroxypropyl guar gum thickener about 40% compared with the conventional wells, and also keep good viscoplastic property and sand- carrying ability. It can reduce the operating friction and significantly decrease the fracturing fluid residue content, and so reduce the damage degree of fracture conductivity and reservoir permeability, improve the effect of fracture reconstruction.

The main technical index:

①Appearance: colorless to yellow liquid

②Solubility: It is miscible with water in any ratio

③Delayed crosslinking time : time is adjustable within 1 to 2 minutes

④Temperature resistant capacity(the HPG mass fraction of 0.25%):≥70℃

⑤Temperature resistant capacity(the HPG mass fraction of 0.35%):≥100℃

⑥Crosslinked state: Available pick hanging with glass rod
