Slickline or wire run hydraulic motor driven mill |
摘要 |
<p>A tool is run in with a bottom hole assembly that includes a seal and support within the tubing where a fish is to be milled. A ported sub allows pressurized fluid pumped from the surface to enter the bottom hole assembly above the sealed support location and to be directed to set an anchor and to a fluid driven motor such as a progressive cavity motor that is in turn connected milling tool at the rotor of the progressive cavity motor. The fluid exiting the stator goes through a debris removal device and can return to the surface through an annulus around the production tubing. A telescoping joint allows the mill to axially progress with a force applied to the fish generated by a tractor or a stack of Belleville washers.</p> |
