Controllable deflection housing, downhole steering assembly and method of use |
摘要 |
<p>This invention relates to a controllable deflection tool. The controllable deflection tool is likely to have its greatest utility as part of a downhole assembly to steer a drill bit during drilling for oil and gas. There is provided a controllable deflection tool having a first end and a second end, the tool having: a conduit for a working fluid; a rotary element adapted for rotation within the tool; a deflection member; a vane motor configured to rotate the deflection member relative to the rotary element; and a valve for controlling the flow of working fluid to the vane motor. There is also provided a downhole steering assembly and a method of steering a downhole drilling assembly incorporating the controllable deflection tool.</p> |
