COMBINED CONTROL PENETRATOR Russian patent published in 2020 - IPC E21B33/38 

FIELD: mining.

SUBSTANCE: invention relates to underwater production, in particular, to devices providing connection of hydraulic and electric lines between underwater fountain fittings of horizontal type and suspension of tubing string. Disclosed is a combined control penetrator for connecting hydraulic and electric lines between an underwater christmas tree assembly and a tubing string suspension comprising a body, a piston arranged inside the housing, made with possibility of movement in axial direction inside the housing between the disconnected position of the piston and the connected position of the piston, wherein the piston comprises a first portion of the piston including, on one of its ends, electrical and hydraulic connectors, made so that when the piston is in the connected position to provide connection of hydraulic and electric lines, the second piston section and the third piston section, balls arranged in cavities made between first and second sections of piston, and second and third sections of piston, wherein in each of first and third sections of piston there are two diametrically opposite support lugs, and in the second section of the piston there are four support lugs, two on each side, wherein holes are made inside the balls, through which fingers pass, held in the support lugs of sections of the piston, wherein the penetrator is equipped with an emergency disconnection mechanism, and the piston movement is carried out hydraulically by means of a hydraulic drive located around the piston end section in the hydraulic drive housing.

EFFECT: technical result is possibility of levelling penetrator angular deviations.
