<p>57 A plug container for holding a well plug prior to release of the plug into a well, which container has a flanged, splined end (14) which mates with a complemental end of a casing adapter member (6), the two ends being secured to each other by a clamping mechanism (8) which permits easy connecting and disconnecting of the two ends, thereby affording easy interchanging of different adapter members. The plug container has a cavity with a diameter (20) larger than the outer diameter of the plug to be retained therein so that pressure equalization around the plug is maintained without an external bypass. Pressure equalization is also maintained adjacent a cap (10) which closes an end (12) of the plug container, by one or more radial openings (148, 150) in an abutment wall (144) of the cap.</p> |
