Design of metal-polymer coiled tubing pipes for oil and gas industry

In the article were suggested variants of constructions of coiled tubing pipes based on polymer materials.The basic technical parameters of pipes were calculated.Exploitation’s area for metal-polymercoiled tubes was defined.
Materials and methods
Design of samples of metal-polymer coiled tubing pipe was based on the constructions of metal-polimer pipelines that are manufactured by companies "Engineering company "Inkomp-neft" andJSC "Pskovgeokabel".Initial design was developed in the "Kompas" program. All calculations were made in the program “Microsoft Office Excel”.
Results
Metal-polymer coiled tubes were researched. Technical and economic parameters of these tubes were defined. Variants of sphere application were suggested.
Сonclusions
The results confirm a high performanceof metal-polymer coiled tubes. It is forecasted that the operation area of the tested tubes will be extend to such well work as removal of liquid from gas wells, a selective effect on the formation, logging and fishing operations, installation graphite filters. It is obvious that in a number of well operations CT series pipes can be replace by steel coiled tubing or geophysical cable.
