Claim:
A recoverable, reinforced and vibration-damping plug for cased wells, said wells being for oil, water, gas or any other similar fluid, wherein the plug may be connected to a conventional tool for installation into, and removal from, conventional casing perforation, high penetration casing perforation and casing perforation using the tubing conveyed perforation system, the plug comprising: a dredging end for connecting to the conventional tool; a pressure equalizing valve mounted in a holding body; a friction ring in the holding body defining a means to show any detachment of the plug from the conventional tool; packing and clamp means to attach to the casing, with the clamp means having friction inserts; position locking means comprising an upper, leftward locking segment and a second lower, rightward segment, which are respectively furnished with springs and stop screws, and a shock absorbing device comprising vibration-damping means arranged in a section of the plug and defining an elastic impact means upon receipt of action-reaction effects from any shot received by the plug due to any discharge produced by a casing perforation method that creates sudden pressure differences in portions of the casing defined above and below the plug.
