摘要： Apparatus is provided for use in power generation, including a fluid-flow-driven power generator for use in a fluid-containing pipe such as a drill pipe as used in oil and gas exploration and extraction. Parts of the generator are removable from the pipe—for example while a drill pipe is downhole within a drilling well—to leave a clear through bore for survey and fishing operations and to enable replacement of the removed parts. The flow-driven generator comprises an impeller connected to a magnet assembly to rotate the magnet assembly when fluid flows past the impeller. This causes relative movement between the magnet assembly and an adjacent electrical coil assembly, the relative movement and magnetic coupling generating an electrical current in the coil assembly. This generated electrical current is used to power electrical devices within the pipe.

摘要： Apparatus is provided for use in power generation, including a fluid-flow-driven power generator for use in a fluid-containing pipe such as a drill pipe as used in oil and gas exploration and extraction. Parts of the generator are adapted to be removable from the pipe—for example while a drill pipe is downhole within a drilling well—to leave a clear through bore for survey and fishing operations and to enable replacement of the removed parts. The removable part may be a flow control assembly, which includes an adjustable flow control nozzle or which receives any one of a set of different size nozzles. The flow-driven generator comprises an impeller connected to a magnet assembly to rotate the magnet assembly when fluid flows past the impeller. This causes relative movement between the magnet assembly and an adjacent electrical coil assembly, the relative movement and magnetic coupling generating an electrical current in the coil assembly. This generated electrical current is used to power electrical devices within the pipe.

摘要： A sealing system between a tubular and a chassis. In some embodiments, the sealing system includes a sealing member and an outer ring. The sealing member is compressed between the chassis and the tubular. The sealing member has a temperature and comprises a resilient material that is expandable as the temperature increases and contractible as the temperature decreases. The outer ring is displaceable to close an annulus between an outer surface of the outer ring and the inner surface of the tubular by expansion of the sealing element, whereby the sealing member is prevented from extruding into the annulus. Further, the outer ring comprises a compliant material that is deformable under load from the sealing element as the sealing element expands.
