Tool for testing downhole tubing
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.
