DEVICE FOR CONNECTING HYDRAULIC AND ELECTRICAL CHANNELS Russian patent published in 2022 - IPC E21B33/04 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry, in particular to the mechanism for orientation of the suspension tubing. A device for connecting hydraulic and electrical channels is proposed, which is part of a X-mas tree, containing a body having at least one hydraulic and electrical channel, inside which there is a tubing suspension, which includes an insert having at least one hydraulic and electrical channel, with a keyed flange assembly attached to it. At the same time, a sleeve is attached to the body, in which the orientation sleeve is installed, having a profile in the form of a spiral, ending with a groove, with which the key for rough orientation interacts, installed on the keyed flange assembly, due to which the hydraulic and electrical channels are preliminary oriented. At the same time, the device has an additional key for precise orientation, mounted on the insert, and a groove made in the body, interacting with each other in such a way that the hydraulic and electrical channels are precisely aligned. Wherein the gap between the groove in the body and the key for precise orientation is less than the gap between the groove, in which the profile in the form of a spiral ends, and the key for rough orientation, installed on the key flange assembly.

EFFECT: improving the accuracy of orientation of the hydraulic and electrical channels of the tubing hanger relative to the channels made in the X-mas tree block.
