摘要 |
<p>A well tool (2; 302a, 302b) and method for in situ introduction of a treatment means (151) into a region of an annulus (12), comprising: an anchoring body (38; 338); a perforation device (234) for making a hole (236) through a pipe structure (4); a storage chamber (142a, 142b) for the treatment means (151); a driving means (132, 144, 150) for the treatment means (151); and a flow-through connection device (192) for injection of the treatment means (151). The distinctive characteristic is that the anchoring body (38; 338) is disposed in an anchoring module (18; 318); wherein the storage chamber (142a, 142b), the driving means (132, 144, 150) and the connection device (192) are operatively connected to an injection module (30; 330); wherein the injection module (30; 330) can be moved axially relative to the anchoring module (18; 318) for moving the connection device (192) in vicinity of the hole (236); and wherein the well tool (2; 302a, 302b) comprises at least one alignment means for alignment and connection of the connection device (192) vis-à-vis the hole (236).</p> |
