ABSTRACT:
A tool is disclosed, e.g. but not limited to a wellbore cementing stage tool, which has a hollow body member with one or more lined ports through which fluid can flow from an interior of the body member to space outside the body member, e.g. to the annulus of a wellbore between an exterior surface of the tool and an interior surface of the wellbore or vice versa. The port or ports are lined with a metal tube which has a portion projecting into the body member. The projecting portion may be crushed shut forming, preferably, a metal-to-metal seal to seal off the corresponding port to flow. A hollow member is disclosed with a port through it which has a metal liner with a portion projecting from the port. Methods are disclosed for using the items with one or more lined ports.
