A gun tube for a downhole perforating gun assembly includes a body having a cavity and one or more weights in the cavity. Gravity acts on the weights, which causes the tube body to rotate around its longitudinal axis so the weights are adjacent the lower part of the wellbore in which the gun assembly is positioned when oriented horizontally. This position shape charges in the gun tube in a desired position prior to the shape charges being fired. The gun tube may also include one or more end connectors with electrical contacts having a first, extended position, and a second, contracted position, and/or end connectors that can be assembled by hand without the use of tools.

Downhole perforating gun tube and components

A downhole perforating gun system provides wireless electrical communication between an inner body conductor, a switch, a detonator, and a feedthrough, and further comprising a weight module and a bearing assembly wherein the weight module is rotatable by a weight via a bearing assembly based on gravity acting on one or more of the weights.

Downhole perforating gun system

A gun tube for a downhole perforating gun assembly includes a body having a cavity and one or more weights in the cavity. Gravity acts on the weights, which causes the tube body to rotate around its longitudinal axis so the weights are adjacent the lower part of the wellbore in which the gun assembly is positioned when oriented horizontally. This positions shape charges in the gun tube in a desired position prior to the shape charges being fired. The gun tube may also include one or more end connectors with electrical contacts having a first, extended position, and a second, contracted position, and/or end connectors that can be assembled by hand without the use of tools.

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.
