FIELD: drilling of wells.
SUBSTANCE: optical electric cable for well media includes several optical fibers located inside a metal tube. Electrically conductive layer surrounds the inner part of the metal tube, the insulating layer surrounds and contacts the electroconductive layer, and the external metal tube surrounds and contacts the insulating layer.
EFFECT: invention solves the problem of providing a downhole cable with a minimum diameter, in particular with a diameter of not more than 4 mm, suitable for use in drilling downhole motor on flexible pipes and providing suitability for introduction into a string of flexible tubing string prior to immersing flexible tubing in an oil or gas well.
