A device is disclosed for setting an annular seal in an annular space formed between a large diameter tubular and a small diameter tubular extending into the large diameter tubular. The device comprises a carrier block suitable to be located at a position in the large diameter tubular proximate said annular space, the carrier block being provided with a carrier ring axially movable relative to the carrier block between a first position and a second position and arranged to axially move the annular seal into the annular space upon movement of the carrier ring from the first to the second position thereof, and further comprising an explosive charge arranged to move the carrier ring from the first position to the second position thereof and a detonator for selectively detonating the explosive charge.

1. A device for setting an annular seal in an annular space formed between a large diameter tubular and a small diameter tubular extending into the large diameter tubular, the device comprising:a first tubular having an inside surface defining an inner diameter; a second tubular having an inside surface defining an inner diameter and an outside surface describing a outer diameter smaller than the inner diameter of said first tubular, said second tubular extending into said first tubular whereby the inside surface of said first tubular and the outside surface of said tubular define an annular space; a carrier block suitable to be located at a position in the first tubular proximate said annular space, the carrier block being provided with a carrier ring axially movable relative to the carrier block between a first position and a second position and arranged to axially move an annular seal into the annular space upon movement of the carrier ring from the first to the second position thereof, and further comprising an explosive charge arranged to move the carrier ring from the first position to the second position thereof and detonator means for selectively detonating the explosive charge.
