SEGMENT OF A CASING TAIL FOR THE ENRICHMENT OF HYDROCARBONS AND METHOD OF ENRICHMENT OF HYDROCARBONS

摘要

1. The casing shank segment for the enrichment of hydrocarbons during their collection from the underground hydrocarbon reservoir, having first and second mutually opposite ends and configured to attach at a horizontal position at both mutually opposite ends to another segment of the casing shank to form an elongated casing shank, wherein each segment of the casing shank contains: an elongated hollow external element of the shank having a longitudinal axis and containing many holes along at least in the area of its perimeter, each of which is large enough to allow fluid hydrocarbon to flow through it; an elongated hollow inner element of the liner concentrically located inside the outer element of the liner along its indicated longitudinal axis, so that a pore space is formed between the inner element of the liner and the outer element of the shank, also having many holes on its perimeter, allowing partially enriched hydrocarbon to flow from the feather space into the specified of the inner liner element; wherein said pore space is configured to be filled with catalyst to enrich the hydrocarbon and increase its fluidity when the hydrocarbon flows through the porous passage and then into the inner liner element through openings in it; the casing liner segment has means for connecting the inner element shank with an external element of the shank; Moreover, the specified means of connecting the inner element of the shank with the outer element of the shank contains
