HIGH PRESSURE BODY Russian patent published in 2019 - IPC E21B47/01 F17C1/00 

FIELD: geophysics.

SUBSTANCE: invention relates to the supporting body structures for geophysical instruments operating under alternating axial loads, torsional and bending moments, as well as high external pressure and temperature. In the device, the bearing element is made in the form of a metal body, consisting of the larger diameter cylindrical part, passing along the longitudinal axis into the smaller diameter protrusion. Bearing part is equipped with a polymer bushing, put on the body and overlapping it along the entire length. Bearing part smaller diameter protrusion is made in the form of a polyhedron, forming a gap between its surface and the insulating bushing inner surface, and is equipped with removable insulating plates according to the edges dimensions. As the sealing elements, the sealing rings are used, to be installed on the bearing element ends from the insulating bushing inner side. Insulating bushing, insulating plates and sealing rings are made of polymer material with high tensile strength.

EFFECT: increase in the structure reliability, its manufacturability and maintainability.
