    摘要: A tubular assembly includes a tubular having at least one opening. A slidable sleeve is slidingly mounted relative to the tubular. The slidable sleeve is shiftable between a first position, and a second position. A biasing member selectively biases the slidable sleeve in one of the first position and the second position. A degradable locking member is mounted relative to one of the tubular and the slidable sleeve. The degradable locking member selectively retains the slidable sleeve in the other of the first position and the second position. The degradable locking member is configured to degrade when exposed to a downhole fluid allowing the biasing member to shift the slidable sleeve back to the one of the first position and the second position.

    摘要: A tubular assembly includes a turbular member having at least one opening, and a sleeve slidingly mounted relative to the tubular member. The sleeve is shiftable between an open configuration in which the at least one opening is exposed and a closed configuration in which the at least one opening is covered by the sleeve. A degradable locking member is mounted relative to one of the turbular and the sleeve. The degradable locking member selectively retains the sleeve in the open configuration. The degradable locking member is configured to degrade when exposed to a downhole fluid allowing the sleeve to be shifted to the closed configuration.
