1. A tool for testing a tubular member, comprising:
- a shaft having a fluid passageway connecting at least one first port and at least one second port;
a sealing element that seals against the tubular member, the shaft moving relative to the sealing element between an open position in which the at least one first port is in fluid communication with the at least one second port and a closed position in which the sealing element closes the at least one first port; and
an anchor that secures the sealing element relative to the tubular member to permit the shaft to move from the open position to the closed position.

Abstract
A tool for testing a tubular has a shaft with a fluid passageway connecting a first port and one or more second ports. A sealing element seals against the tubular member. The shaft moves relative to the sealing sleeve between an open position in which the first port is in fluid communication with the second port and a closed position in which the sealing sleeve closes the first port. An anchor secures the sealing sleeve relative to the tubular member to permit the shaft to move from the open position to the closed position.

8. A method of testing a tubular, comprising the steps of:
-
providing a tool comprising; a shaft having a fluid passageway connecting at least one first port and at least one second port; a sealing element, the shaft moving relative to the sealing element between an open position in which the at least one first port is in fluid communication with the at least one second port and a closed position in which the sealing element closes the at least one first port; and an anchor that secures the sealing element relative to the tubular member to permit the shaft to move from the open position to the closed position; positioning the tool in a tubular to be tested with the tool in the closed position and such that the sealing element seals against the tubular; pumping fluid into the tubular above the tool, the fluid being retained above the tool by the sealing element; observing to see whether the fluid is retained within the tubular; and moving the shaft to the open position to allow the fluid to drain from above the tool through the fluid passageway. - View Dependent Claims (9, 10, 11, 12, 13)
