PRODUCTION STRING ACTIVATED WELLBORE SEALING APPARATUS AND METHOD FOR SEALING A WELLBORE USING A PRODUCTION STRING |
摘要 |
<p>A wellbore sealing apparatus positioned along production string tubing is provided to allow for sealing of a wellbore without needing to use a work string. The sealing apparatus includes an outer sleeve, an inner mandrel telescopically received within the outer sleeve, a sealing element positioned on the inner mandrel, an actuator interaction assembly and top and bottom seal pushers. An actuator positioned along the production rod string is also provided. The wellbore sealing apparatus has a sealed or engaged position and a disengaged position. To seal the wellbore, the actuator is pulled upwardly via the production rod string and couples to the actuator interaction assembly of the sealing apparatus. The continued upward movement of the actuator results in the inner mandrel moving further into the outer sleeve and the top and bottom pushers exerting opposing forces on the sealing element. The sealing element compresses and expands to seal the wellbore.</p> |
