Abstract
A gun tube for a downhole perforating gun assembly includes a body, a first end, and a second end. A motor is directly or indirectly attached to one or both of the ends and is configured to rotate the gun tube around its longitudinal axis in order to position shape charges in the gun tube in a desired position before firing the shape charges. A sensor may be on the gun tube, a sub-assembly, or an outer casing to detect the relative position of the shape charges and a signal including the position of the shape charges could be sent to a human or machine operator.
Claims30
A gun tube comprising:
- a body having a cavity, a longitudinal axis, a first end, and a second end;
- a first end fitting attached to the first end of the body, wherein the first end fitting comprises:
- a bearing housing that includes ball bearings and a central opening;
- and
- a support having a first portion with a first diameter and a second portion with a second diameter that is greater than the first diameter, wherein the bearing housing is positioned on the first portion and the central opening surrounds at least part of the first portion;
- and
- a motor connected to the first end of the body, the motor configured to rotate the body around the longitudinal axis.
A gun tube, comprising:
- a body having a cavity, a longitudinal axis, a first end, and a second end;
- a first end fitting attached to the first end of the body, wherein the first end fitting includes a first end contact having a first, extended position and a second, contracted position;
- a second end fitting attached to the second end of the body, wherein the second end fitting includes a second end contact having a first, extended position and a second, contracted position;
- and
- a motor connected to at least one of the first end and the second end of the body, wherein the motor is configured to rotate the body around the longitudinal axis.
A gun tube, comprising:
- a body having a cavity, a longitudinal axis, a first end, and a second end;
- a first end fitting attached to the first end of the body, wherein the first end fitting comprises an end contact having a first end that comprises a stem, the stem being positioned inside of the cavity, and the end contact having a second end, the second end comprising an electrical contact that is positioned outside of the body;
- and
- a motor connected to the first end of the body, wherein the motor is configured to rotate the body around the longitudinal axis.
A gun tube, comprising:
- a body having a cavity, a longitudinal axis, a first end, and a second end;
- a first end fitting attached to the first end of the body, wherein the first end fitting comprises a first end contact that includes a housing and one or more frangible elements extending outwardly from the housing;
- and
- a motor connected to the first end of the body, wherein the motor is configured to rotate the body around the longitudinal axis.
