Abstract
The present invention provides for a perforating gun having stackable sections that latch, enabling the gun string to carry both compressive and tensile loads. This allows for the downhole assembly of guns of any desired length, and for the entire gun string to be removed after firing.
Claims20
A perforating assembly for use in a well comprising:
- a deployment string;
- a gun string comprising at least two sections, each section being individually deployed by the deployment string;
- and
- a connector to join each adjacent pair of sections such that the gun string can carry compressive and tensile forces.

A connector for use in a well comprising:
- an upper portion having a housing, an upper ring disposed within the housing, and an upper ballistic transfer member;
- and
- a lower portion having a lower ring complementary to the upper ring, a profile in the lower ring, and a lower ballistic transfer member.
A method of perforating a well comprising:
- attaching a deployment tool to a first section of a perforating gun string;
- running in the first section to a desired location in the well;
- releasing the first section from the deployment tool;
- retrieving the deployment tool;
- attaching the deployment tool to a second section of the perforating gun string;
- running in the second section until it joins with the first section to form a union capable of carrying compressive and tensile forces;
- firing the perforating gun string;
- and
- retrieving the perforating gun string.
