Abstract:
A variable orientation downhole actuation tool disposed near the end of a down hole tube, includinga first part having a respective axis and joined to the down hole tube whose orientation is fixed relative to the down hole tube, and a second part having a respective axis and fixed by articulation to the first part, whose orientation may be adjusted relative to the axis of the first part, the orientation of the second part being adjustable so as to vary a first angle included between the first part and the second part, a second angle through which the second part is rotated relative to the axis of the first part, and a third angle through which the second part is rotated about the axis of the second part, these three angles being independently adjustable, the articulation between the first part and the second part including: a first actuating member capable of substantially axial movement relative to the first part, and a first following member, which the first actuating member bears against such that axial movement of the first actuating member causes a substantially transverse movement of the first following member, a second actuating member capable of substantially axial movement relative to the first part, and a second following member, which the second actuating member bears against such that axial movement of the second actuating member causes a substantially transverse movement of the second following member independently in an orthogonal direction to the transverse movement of the first following member.
