Abstract
A geological perforating tool (gun) shape charges disposed at an angle that provides an improvement over other known embodiments by accurately securing the charges in the tool to facilitate reliable, reproducible focus of the shaped charges. Charges are disposed on metal strips fitted into slots that are precision cut at predetermined angles in a tool barrel circumference.
Claims10
A perforating tool comprising:
- a cylindrical barrel having angled circular cutouts for placement of shaped charges in shape charge cases;
- support strips comprising metal strips with a centered hole to receive a shape charge case, wherein the shape charge cases have a circumferential projection that will not pass through the hole and which provides support for a shaped charge case on the strip;
- slots cut into the cylindrical barrel to support the edges of the support strips, cut at a predetermined angle to provide angled direction for perforations in a geological formation from explosion of the shaped charges.
A method of producing intersecting perforations in a geological formation comprising providing a perforating gun disposed at a desire location comprising:
- a cylindrical barrel having angled circular cutouts for placement of shaped charges in shape charge cases;
- support strips comprising metal strips with a centered hole to receive a shape charge case, wherein the shape charge cases have a circumferential projection that will not pass through the hole and which provides support for a shaped charge case on the strip;
- slots cut into the cylindrical barrel to support the edges of the support strips, cut at a predetermined angle to provide angled direction for perforations in a geological formation from explosion of the shaped charges;
- and
- detonating the shaped charges.
