摘要
A valve assembly is mounted with the setting tool for a hydraulically actuated well packer. The valve is located at a fluid passage in the setting tool and movable to control fluid flow from inside the setting tool to the well packer setting mechanism. In using this equipment, the valve is open when the setting tool is positioned within the well packer for setting of the well packer so fluid can pass through the setting tool and into the packer hydraulic setting mechanism. The valve is closed when the setting tool is removed from the well packer in order that fluid can flow through the setting tool and also through the bore of the well packer mandrel for fluid communication through the well tubing to a location below the packer without leakage into the annular cavity above or below the packer.
