International Classification:

E21B 2300

US Classification:

1661175

Abstract:

A mandrel for use in the well tubing in which the mandrel has an open bore for alignment with the well tubing and a side pocket offset from the open bore for receiving flow control devices and an orienting sleeve in the open bore above the pocket for aligning a flow control device to be positioned in the pocket. The orienting sleeve includes an elongated hollow tubular body with a lower end which tapers upwardly and away from the offset pocket to form a guide surface and a first longitudinally extending slot extends from the highest portion of the tapered guide surface and terminates in spaced relation to the upper end of the sleeve. A second slot of relatively narrow width in relation to the first slot extends from the termination of the first slot to the upper end of the tubular body to form spaced aligned shoulders at the juncture of the first and second slot and a passage way for relieving or discharging trash and debris from the first slot into the well tubing.

Abstract:

A mandrel for use in a well tubing in which the mandrel body has an open bore for alignment with the well tubing and an enlargement offset from the open bore with a side pocket therein for receiving a flow control device. A combination guard and guide has a body which forms part of the mandrel offset and is positioned above the side pocket to prevent access to the pocket except by a predetermined size member. A projection is provided between the combination guard and guide and the side pocket to assist in retaining a flow control device in position in the pocket. An orienting sleeve is mounted in the open bore of the mandrel above the pocket for aligning a flow control device to be positioned in the pocket, which orienting sleeve comprises a tubular body having a tapered lowered end and a first longitudinal slot angularly disposed relative to the mandrel offset in a predetermined relationship. The first longitudinal slot terminates in spaced relation to the top end of the sleeve and a second slot communicates with the top end of the slot to provide a means for discharging trash and debris from the slot.
