Abstract
A rotating diverter for isolating fluid in a well from other fluid above the well is provided. The rotating diverter includes a housing body which has a bore running through it. A retrievable spindle assembly which includes a spindle and a bearing assembly is disposed in the bore. The bearing assembly supports the spindle for rotation. The spindle is adapted to receive and seal around a tubular member, and rotation of the tubular member rotates the spindle within the bore. A lock member is disposed in the housing body to secure the retrievable spindle assembly to the housing body.
Claims17
A rotating diverter, comprising:
- a housing body having a bore running therethrough;
- a retrievable spindle assembly disposed in the bore, the retrievable spindle assembly comprising a first spindle and a first bearing assembly for rotatably supporting the first spindle, the first spindle being adapted to slidingly receive and sealingly engage a tubular member, wherein rotation of the tubular member rotates the first spindle within the bore, the first spindle having thereon a pair of opposed sealing elements;
- and
- a lock member disposed in the ho using body for securing the retrievable spindle assembly to the housing body.
