发明名称 METHOD OF DRYING A TUBULAR STRING TO PREVENT BEDWRAP CORROSION
摘要 Embodiments of the present invention generally relate to a method of drying a tubular string to prevent bedwrap corrosion. In one embodiment, a method of drying a tubular string includes deploying a first bypass pig in the tubular string. The method further includes injecting propellant behind the first bypass pig, thereby driving the first bypass pig through the tubular string. A portion of the propellant bypasses the first bypass pig, thereby drying an inner surface of the tubular string.
