MANIPULATING A DOWNHOLE ROTATIONAL DEVICE

摘要

In accordance with embodiments of the present disclosure, a system includes a valve housing with a port formed in a wall of the housing, a rotation sleeve disposed in the valve housing, an orienting sleeve with an orienting feature disposed in and fixed to the valve housing, and a shifter. The rotation sleeve is rotatable relative to the valve housing and includes a port formed therethrough. The shifter includes engagement features disposed a distance from each other along a length of the shifter and a rotational distance from each other about a circumference of the shifter. The engagement features are receivable into corresponding features of the orienting sleeve and the rotation sleeve to rotate the rotation sleeve relative to the valve housing as the shifter travels through the valve housing. The disclosed system may be used to selectively manipulate any number of valves in downhole equipment.

主权项

1. A system, comprising:
a valve housing comprising a port formed in a wall of the valve housing; a rotation sleeve disposed in the valve housing, wherein the rotation sleeve is rotatable relative to the valve housing and comprises a port formed therethrough, and wherein the rotation sleeve comprises a rotation feature; an orienting sleeve disposed in and fixed to the valve housing at a position adjacent the rotation sleeve, wherein the orienting sleeve comprises an orienting feature; and a shifter comprising at least two engagement features formed on an outer diameter of the shifter, the engagement features being disposed a distance from each other along a length of the shifter and a rotational distance from each other along a circumference of the shifter; wherein the engagement features are receivable into corresponding features of the orienting sleeve and corresponding features of the rotation sleeve to rotate the rotation sleeve relative to the valve housing as the shifter travels through the valve housing.
