摘要： Apparatus and method for cooling a component inside a tool includes a container and a plurality of heat sinks positioned in the container. The components are positioned in the container with the heat sinks for maintaining a reduced temperature inside the container. Further, an insulating layer and a reflective layer surround the heat sinks and components to reduce heat transfer. Alternatively, the container can have a hollow wall that encloses the space in which a heat sink material (such as an eutectic material) is disposed. The components to be protected are located in the container. The eutectic material includes a composition having tin and zinc. The insulating layer includes a container that stores a vacuum layer, such as a dewar flask.

摘要： An apparatus and method for sealing an inner wall of a portion of a casing positioned in a well employs an inflatable sleeve having an outer surface and a conformable composite sleeve of curable composition extending around the outer surface of the inflatable sleeve. The inflatable sleeve is inflated to compress the composite sleeve against the surface of the inner casing wall. A local, activatable energy source, positioned downhole to deliver heat to the composite sleeve, is activated to cure the composite sleeve to form a hardened sleeve. The hardened sleeve presses against the inner wall of the casing portion to create a fluid seal. The embodiments shown have a number of preferred features. The local energy source includes an exothermic heat energy source for generating heat energy to cure the composite sleeve. The composite sleeve includes a mixture of resin and a curing agent, and the exothermic heat source includes thermite. The thermite includes a composition having a metal oxide and a reductant. A starter mix is positioned adjacent the exothermic heat energy source, and the starter mix is ignited to start an exothermic reaction in the heat energy source. A conformable layer extends around the composite sleeve, with the layer serving to form a seal between the composite sleeve and the inner wall of the casing portion.

摘要： An apparatus and method provides an anchoring apparatus for use in a wellbore that comprises a gripping assembly and an actuation assembly. In one arrangement, the actuation assembly includes a motor and a module having at least a compressible element (e.g., a hydraulic module) between the motor and the gripping assembly. Upon activation, the motor actuates the hydraulic module to cause activation of the gripping assembly. In one arrangement, the anchoring apparatus is designed to pass through a tubing or other restriction in the wellbore. When in the retracted state, the gripping assembly of the anchoring apparatus has an outer diameter that is smaller than an inner diameter of the tubing. When in the expanded state, the gripping assembly of the anchoring apparatus has an outer diameter than is substantially the same as the inner diameter of the liner to enable engagement of the gripping assembly against the liner.

摘要： A perforating gun includes a guide, a first charge unit, a second charge unit and a linkage. The first and second charge units are coupled to the guide. The second charge unit is capable of being in a collapsed position for passing the second charge unit through a tubing and is capable of being in an expanded position for detonating the second charge unit. The linkage is connected to the second charge unit to communicate an applied force to cause the second charge unit to move the second charge unit along the guide toward the first charge unit when the second charge unit is at least partially in the expanded position.
