摘要: The invention provides a tool for pressure stage differential type spraying, setting and fracturing pipe column comprising the same. comprises tubular upper connector, connecting sleeve, center pole, packer, lower connector an inner barrel, wherein spray nozzle hole are arranged on connector; barrel is wall of to block hole. Under first action, moves downwards, so that exposed, packer set, then perforating performed through nozzle. second downwards continuously, as enable be exposed conduct operation. Through adoption tool, operation cost can reduced.
