FLEXIBLE CONNECTION FOR WELL COMPLEXES Russian patent published in 2018 - IPC E21B47/01 

FIELD: drilling of soil or rocks; mining.

SUBSTANCE: invention relates to the field of research, diagnostics and processing of oil, gas, water and other wells and is intended for flexible connection of various geophysical and other modules in order to increase the long structures passability. Device contains two connecting bushings. By one side each of the bushings is attached to the downhole complex connected modules, and by the other side the connecting bushings are connected to each other by at least two flexible cables. Connecting bushings are made with axial holes in which electrical wires are laid and said connection is filled with silicone flush with the downhole complex external outline. Flexibility of the proposed connection is provided by cables connecting the bushings, which are attached to the complex modules by means of a threaded or other connection. Bushings have axial holes for passing electrical wires. Bushings and cables are filled with silicone flush with the borehole complex outline.

EFFECT: increasing the connection reliability, saving the downhole operations and works in the well performance time.
