FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: group of inventions relates to oil and gas industry and can be used in arrangement and operation of wells for production of hydrocarbons (oil, gas, gas condensate) or water, their ground transportation, as well as for transportation of chemical reagents intended to prevent hydrate formation/corrosion in pipelines. Flexible load-bearing tube comprises inner polymer layer 1, reinforcing elements 2, outer polymer layer 3 and built-in cables 4. Built-in cables 4 are arranged in layer 1 under reinforcing elements 2. Embedded cables 4 can be power or data. Information cables can be electric or fibre-optic. Well for extraction of hydrocarbon raw material includes casing string, tubing and wellhead equipment. Tubing string is made in the form of the claimed flexible pipe.
EFFECT: technical result consists in reduction of probability of damage of built-in cables during production and transportation of flexible pipe, as well as in improvement of reliability and safety of power supply and data transmission when using pipe; besides, the declared solution provides simplification of the well development and operation and improvement of its operational reliability.
