Abstract
A method and apparatus for using a plurality of impact dampening discs composed of a closed cell polyurethane foam composite with polyborodimethylsiloxane as a dilatant non-Newtonian fluid dispersed through a foam matrix in a downhole setting tool to absorb the energy released during setting operations.
Claims12
A setting tool apparatus comprising:
- a first cylindrical body with an inner bore;
- a second cylindrical body with an inner bore, being coaxial with and coupled to the first cylindrical body;
- a third cylindrical body slideably engaged with a first end engaged to the inner bore of the first cylindrical body and having an inner cavity with an axial opening at the first end adapted to accept a power charge and a having a distal end with a shoulder slideably engaged with the second cylindrical body inner bore;
- a fourth cylindrical body with a first end coupled to the distal end of the third cylindrical body and having a distal end with a transverse slot;
- a fifth cylindrical body fixed to a distal end of the second cylindrical body and having an inner bore wherein the fourth cylindrical body is slideably engaged therewith and further having a radial face within the second cylindrical body;
- a plurality of impact dampening discs composed of a closed cell polyurethane foam composite with polyborodimethylsiloxane as a dilatant non-Newtonian fluid dispersed through a foam matrix with a hollow center having the fourth cylindrical body located therethrough and coupled to the radial face of the fifth cylindrical body;
- a sixth cylindrical body coupled to the fifth cylindrical body and having a transverse slot;
- and
- wherein the shoulder of the third cylindrical body engages the plurality of impact dampening discs when the third cylindrical body travels a predetermined distance within the second cylindrical body.

A setting tool apparatus comprising:
- a cylindrical body having a center axis, a first end, a second end, an inner surface, and an outer surface;
- a first piston located within the cylindrical body and axially aligned with the cylindrical body, having a first end and a second end, the first end coupled to a second cylindrical body with a raised radial shoulder;
- a cylindrical mandrel extending from the second end of the first piston and being axially aligned with the cylindrical body;
- a cylinder head coupled to the second end of the cylindrical body and axially aligned with the cylindrical body and having an inner radial face with the cylindrical mandrel located therethrough;
- a plurality of impact dampening material discs composed of a closed cell polyurethane foam composite with polyborodimethylsiloxane as a dilatant non-Newtonian fluid dispersed through a foam matrix in contact with the inner radial face;
- and
- wherein the plurality of impact dampening material inserts absorb the energy of the first piston moving downhole within the cylindrical body without a dampening fluid.
