Abstract

Oppfinnelsen vedrører olj e/gassbrønn-verktøy som styres i brønnen på en wireledning, elektrisk ledning eller som del av produksjonsrørstrengen, og vedrører spesielt avtetnings- eller pakningsverktøy som tilveiebringer en trykk/fluid-barriere. Oppfinnelsen tilveiebringer et nedihullsverktøy (5) omfattende i det minste én ring (12) med bladformede utvidelser (50), hvilken ring (12) er anordnet rundt en lengde-akse av verktøyet (5), og anordninger for styrbart å deformere de bladformede utvidelser (50) slik at disse utvidelser (50) kan beveges styrbart under bruk. Nedihullsverktøyet (5) vil kunne være et avtetnings/pakningsverktøy som benyttes for å til-veiebringe en trykk/fluid-barriere. Den styrbare bevegelse kan bevirke at utvidelsene (50) bringes i tett nærhet av en innerflate av en ledning (55) . Verktøyet vil ytterligere kunne omfatte et elastisk deformerbart pakningselement (10) .The invention relates to oil / gas well tools which are controlled in the well on a wire line, electrical line or as part of the production tubing string, and in particular relates to sealing or packing tools which provide a pressure / fluid barrier. The invention provides a downhole tool (5) comprising at least one ring (12) with blade-shaped extensions (50), which ring (12) is arranged around a longitudinal axis of the tool (5), and means for controllably deforming the blade-shaped extensions (50) so that these extensions (50) can be moved controllably during use. The downhole tool (5) could be a sealing / packing tool used to provide a pressure / fluid barrier. The controllable movement can cause the extensions (50) to be brought in close proximity to an inner surface of a wire (55). The tool may further comprise an elastically deformable packing element (10).
