| 发明名称 | Sliding sleeve valve and method for fluid treating a subterranean formation | ||
| 摘要 | A sliding sleeve valve for wellbore operations includes: a tubular body including a tubular wall including an outer surface and an inner surface defining an inner bore; a fluid port extending through the tubular wall and providing fluidic communication between the outer surface and the inner bore; a sliding sleeve in the inner bore slidably moveable between a port closed position and a port open position, the sliding sleeve including a ball seat on which a plug is landed to move the sleeve from the port closed position to the port open position; an initial sleeve holding mechanism for holding the sliding sleeve in the port closed position, the initial sleeve holding mechanism selected to be overcome by landing a plug on the ball seat to move the sliding sleeve; and a second sleeve holding mechanism for holding the sliding sleeve in the port closed position after the sliding sleeve is reclosed from the port open position to the port closed position, the second sleeve holding mechanism selected to be overcome by landing a plug on the ball seat to move the sliding sleeve. | ||
