摘要： An apparatus and method for placing a member in a wellbore. The apparatus includes member conveyable downhole, a component of the member configured to perform an action in the wellbore, a potential energy source, a locking device and a heat source. The potential energy source is capable of activating the component. The locking device constrains the potential energy source from activating the component when the locking device is in a first state. The heat source changes the locking device from the first state to a second state in which the locking device allows the potential energy source to activate the component.

摘要： An apparatus for generating power includes a fluid chamber configured to receive borehole fluid, one or more conductive coils surrounding the fluid chamber, a reciprocating magnetic shuttle disposed in the fluid chamber and dividing the fluid chamber into a first volume and a second volume, a first conduit connected to the first volume, and a second conduit connected to the second volume, the first conduit and the second conduit extending from a tubular conduit to an annulus. The apparatus includes a switching assembly configured to alternate between a first operating state where the first volume is in fluid communication with the annulus and a second operating state where the first volume is in fluid communication with the tubular conduit, to alternate a direction of differential pressure between the first volume and the second volume and cause the magnetic shuttle to move in a reciprocating motion and generate an electric current.

摘要： A method for joining ductile iron with steel includes the steps of depositing a metallic material between a first ductile iron component, and a second steel component. The joint formed by the method has an interface disposed between the two components and the first and second components are welded thereto. The interface includes the metallic material. The metallic material preferably includes nickel sprayed to the joint area. The resulting interface material is a weld bead zone that preferably includes nickel at a concentration ranging from about twenty-two percent to about thirty-two percent, most preferably between about thirty percent and about thirty-two percent. The welding step of the present invention preferably includes the use of laser energy to localize fusion of the components and the metallic material.
