FIELD: oil and gas industry.SUBSTANCE: invention presents extended, generally cylindrical outer element of liner and extended inner element of liner located concentrically inside it. Catalyst for hydrocarbons enrichment is located in pore space between two elements. Outer elements of liner may have thread connection with each other. Means for sliding connection between outer segment of liner and inner segment of liner is provided to consider various thermal expansion between two segments of liner. Also method of use of segments of well liner including initially a catalyst for enrichment of hydrocarbons and method of well liner segment making are proposed.EFFECT: increasing efficiency of hydrocarbon production from subsurface.16 cl, 14 dwg |
