Benefits of technology

This patented technology allows for an integrated system that combines various aspects such as producing oils from different parts or detects any changes made during their manufacturing process with liquids injected into them. It also includes multiple sections where there may be no heaters at all without causing excessive power consumption. Overall this innovation improves efficiency by controllably adjusting resistances while minimizing wasteful use of electricity.

Problems solved by technology

This technical problem addressed by this patented technology relates to an improved type of oil-production tubular member called Oil Pipe Pump (OPS).

Abstract

The invention relates to a multifunctional composite oil and gas well integrated continuous oil extraction string which comprises an oil pipe and a sleeve, a heating cable, a sampling pipe, a liquid injection pipe, a temperature measuring cable and a pressure measuring cable are arranged in an annular space between the oil pipe and the sleeve, and a heat preservation filling layer is arranged in the annular space between the oil pipe and the sleeve. A non-heating section, a transition section and a heating section are sequentially arranged on the continuous oil extraction pipe column from top to bottom in the length direction, a heating cable of the non-heating section comprises a central copper stranded conductor, the diameter of the copper stranded conductor ranges from 20 mm to 30 mm, a heating cable of the transition section comprises a central nickel-chromium alloy conductor, and the diameter of the nickel-chromium alloy conductor ranges from 10 mm to 20 mm. The heating cable of the heating section comprises a nickel-chromium alloy conductor in the center, and the diameter of the nickel-chromium alloy conductor is 2-10 mm. The continuous oil extraction pipe column integrates oil extraction, heating, detection, sampling and liquid injection, the functions are comprehensive, the whole oil extraction pipe column comprises a non-heating section, a transition section and a heating section, and energy can be saved.
