Abstract
Official abstract text for this publication.
A magnetic pulse actuation arrangement including an inductor, a workpiece spaced from the inductor, a reluctance reduction configuration in magnetically operable communication with the inductor and the workpiece. Also included is a method for completing a borehole including running an arrangement as in any prior embodiment into the borehole, configuring the arrangement to reduce reluctance, generating a magnetic pulse, and moving a workpiece.
First claim
Opening claim text (preview).
What is claimed is: 1 . A magnetic pulse actuation arrangement comprising: an inductor; a workpiece spaced from the inductor; a reluctance reduction configuration in magnetically operable communication with the inductor and the workpiece. 2 . The arrangement as claimed in claim 1 wherein the configuration is a magnetically permeable fluid. 3 . The arrangement as claimed in claim 2 wherein the fluid is a liquid. 4 . The arrangement as claimed in claim 2 wherein the fluid is a magnetorheological fluid. 5 . The arrangement as claimed in claim 2 wherein the fluid has a relative magnetic permeability greater than 1. 6 . The arrangement as claimed in claim 2 wherein the fluid is maintained within the arrangement. 7 . The arrangement as claimed in claim 2 wherein the fluid is pumped in the form of a pill to the arrangement. 8 . The arrangement as claimed in claim 2 wherein the fluid is stored proximate a target location and supplied to the arrangement. 9 . The arrangement as claimed in claim 1 wherein the configuration is a magnetically permeable solid. 10 . The arrangement as claimed in claim 9 wherein the solid is a ring. 11 . The arrangement as claimed in claim 1 wherein the arrangement includes a cone interactive with the configuration. 12 . A method for completing a borehole comprising: running an arrangement as claimed in claim 1 into the borehole; configuring the arrangement to reduce reluctance; generating a magnetic pulse; and moving a workpiece. 13 . The method as claimed in claim 12 wherein the generating includes saturating a magnetic field between the inductor and the workpiece. 14 . The method as claimed in claim 12 wherein the configuring includes carrying a magnetically permeable fluid with the arrangement. 15 . The method as claimed in claim 12 wherein the configuring includes supplying a magnetically permeable fluid to the arrangement in the borehole. 16 . The method as claimed in claim 12 wherein the configuring includes storing a magnetically permeable fluid near a target area and supplying the magnetically permeable fluid to the arrangement. 17 . The method as claimed in claim 12 wherein the configuring is shifting a reluctance reduction configuration.
