摘要： A method and system that uses the flow of drilling fluid to cool electrical components in a downhole environment. A substantially cylindrical housing comprises a wall which houses at least one electrical component directly coupled to a thermoelectric cooling device. An opposing surface of the thermoelectric cooling device contacts a flow of drilling fluid through a hollow passageway in the wall. The flow of drilling fluid acts as a heat sink to transfer heat from the cooling device to a remote location. In this manner, heat is efficiently and directly transferred from the electrical component to the cooling device to the drilling fluid, while the location of the present system within a wall of the housing enables reliable protection of sensitive electrical components from hostile effects downhole.

摘要： A robust data transmission element for transmitting information between downhole components, such as sections of drill pipe, in the presence of hostile environmental conditions, such as heat, dirt, rocks, mud, fluids, lubricants, and the like. The data transmission element components include a generally U-shaped annular housing, a generally U-shaped magnetically conductive, electrically insulating element such as ferrite, and an insulated conductor. Features on the magnetically conducting, electrically insulating element and the annular housing create a pocket when assembled. The data transmission element is filled with a polymer to retain the components within the annular housing by filling the pocket with the polymer. The polymer can bond with the annular housing and the insulated conductor but preferably not the magnetically conductive, electrically insulating element. A data transmission element is mounted within a recess proximate a mating surface of a downhole drilling component, such as a section of drill pipe.

摘要： A system for transmitting data through a string of downhole components. In one aspect, the system includes first and second magnetically conductive, electrically insulating elements at both ends of the component. Each element includes a first U-shaped trough with a bottom, first and second sides and an opening between the two sides. Electrically conducting coils are located in each trough. An electrical conductor connects the coils in each component. In operation, a varying current applied to a first coil in one component generates a varying magnetic field in the first magnetically conductive, electrically insulating element, which varying magnetic field is conducted to and thereby produces a varying magnetic field in the second magnetically conductive, electrically insulating element of a connected component, which magnetic field thereby generates a varying electrical current in the second coil in the connected component.

摘要： This invention presents a high-pressure high-temperature reaction vessel having a metallized graphite heater for improved performance. The metallized heater consists of a graphite tube comprising a refractory metal. Metallization of the graphite heater is accomplished either by coating the graphite tube with a refractory metal, by intermixing a refractory metal in the graphite, or by positioning a refractory metal sheet or cylinder adjacent the graphite heater. The refractory metal constrains the graphite heater, adds toughness to the heater, shields the heater from outside contamination, and provides an electrical contact for a thermocouple.
