摘要: The present invention relates to a downhole tool (102) for selectively opening and closing a lateral borehole extending from a primary borehole. The tool (102) comprises a body (104) incorporating a wall provided with an opening (116) extending therethrough; a deflector member (106) slidably mounted in the body (104) and having a deflecting surface (126) for deflecting, in use, downhole equipment laterally within the body (104). The deflector member (106) is slidable between an open position, in which the deflecting surface is located adjacent and facing towards said opening so that, in use, downhole equipment laterally deflected by the deflecting surface is directed through said opening, and a closed position, in which the deflecting surface is oriented relative to said opening so as to prevent downhole equipment from being laterally deflected through said opening during use. In either position, equipment may pass into the primary borehole downhole of the primary/lateral junction. The tool (102) also comprises constraining means (138, 140) for restricting movement of the whipstock relative to the body.

摘要: A connector for connecting a first wellbore tubular to a second wellbore tubular includes a tubular housing connectable to the second tubular and an internal surface facing an internal bore, and a ramp assembly arranged around the surface having a plurality of elongate ramp arrays and a plurality of elongate channels arranged to separate adjacent ramp arrays. The connector includes a slip body which is insertable into the internal bore having an internal surface with at least one slip tooth for engaging the first tubular, an external surface and a ramp assembly arranged around the external surface having a plurality of elongate ramp arrays which grip the first tubular and a plurality of elongate channels arranged to separate adjacent ramp arrays. The ramp arrays of the slip body are each alignable with a respective channel of the tubular housing. The slip body is rotatable within the tubular housing.
