Forsinket borattværbundet fraktureringsfluid med forøget temperaturinterval |
摘要 |
A method of fracturing a subterranean formation comprises providing an aqueous hydrated galactomannan gum fluid; adding to the hydrated galactomannan gum fluid a base and an organic polyol; adding an encapsulated soluble boron-containing compound to the hydrated galactomannan gum fluid containing a base and an organic polyol; and pumping the galactomannan gum fluid with the added components into a wellbore to a subterranean formation at fracturing pressures. |
