▎ 摘　　要

NOVELTY - Manufacture of swellable article involves disposing (104) a graphene-based material (14) in a matrix (22) material to yield a swellable material (10), forming (106) the swellable material into an article which is swellably responsive to a selected fluid, exfoliating the graphene-based material in the article, and arranging the graphene-based material operatively to facilitate the swelling of the article upon exposure to a selected fluid by sorbing the fluid. USE - Manufacture of swellable article used for packer, sealing device, isolation and actuation used in downhole and drilling completions industry. ADVANTAGE - The method provides excellent sealing characteristics, and ensures excellent pliability, durability, swellability, strength and pressure rating of the resulting article. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of using swellable article, which involves exposing (110) the manufactured swellable article to a selected fluid, swelling the swellable article with the selected fluid, sorbing the fluid with the graphene-based material in order to facilitate the swelling, and engaging the swellable article with an adjacent structure after swelling. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of manufacture of swellable article. Swellable article (10) Graphene-based material (14) Intercalant (16) Matrix (22) Tubular (28) Bore hole (30) Arranging process (104) Formation of swellable article process (106) Exposure process (110)
