DYNAMICALLY AUTOMATED ADJUSTABLE DOWNHOLE CONVEYANCE TECHNIQUE FOR AN INTERVENTIONAL APPLICATION |
摘要 |
A method for conveying an interventional tool downhole in a substantially self-piloting fashion. The method includes moving the tool in the well while using a communicative conveyance line coupled to a winch at the oilfield surface. Thus, real-time readings regarding downhole tool speed, line tension, etc. may be analyzed at surface and utilized to adjust the moving of the tool in an ongoing feedback loop. As a result, the adjustments are made based on true circumstances downhole as opposed to surface-based readings which may otherwise be less accurate. Therefore, efficiency of the operations may be maximized, operator time freed and the likelihood of catastrophic line based failures reduced. |
