摘要： A well cementing valve is shown which includes a tubular mandrel having at least one lateral port and which is adapted to be made in a well tubing string. An external seal ring having a seal region circumscribes the mandrel on one side of the lateral port. An axially movable sleeve valve initially covers the mandrel ports on the mandrel exterior. The sleeve valve has a pressure responsive seal area subject to fluid pressure in the mandrel for moving the sleeve valve. An axially slidable protective sleeve initially surrounds the mandrel and the sleeve valve. A plurality of shear pins connect the protective sleeve to the sleeve valve to restrain the sleeve valve against axial displacement. The pressure responsive seal area on the sleeve valve is operable to apply a shearing load on the pins to permit an axial displacement of the protective sleeve and an opposite axial displacement of the sleeve valve to open the ports.

摘要： An equipment insert is shown for use within a section of well pipe. The equipment insert is installed within the pipe bore at the well surface. The equipment insert is run into the bore of the well pipe and manipulated with a hand tool to actuate gripping slips and a seal ring to grip the pipe interior bore and to form a seal with the interior bore of the section of well pipe. The section of well pipe containing the equipment insert can then be made up in the well pipe string, and the well pipe string can be run into the well bore for conducting well bore operations.
