摘要：A core barrel hole plug. A plug body sized to easily fit the hole to be plugged is slidably attached to a flange sized larger than the hole to limit the movement of the plug body into the hole. A rectangular bore at the inner end of the plug body has a pair of pawls pivotally mounted therein which are moveable between retracted and extended positions for releasing or locking the plug in position. An actuator screw is threadably engaged through a cylindrical bore in the plug body and in communication with the rectangular bore where a cam on the actuator screw causes movement of the pawls between the release and locking positions. The flange and screw are adapted to receive a remotely operated tool for remote operation of the assembly.
