Abstract
A blanking plug device, system and method of use, wherein the plug device has an anchoring portion for securing the blanking plug device within a tubing string or other well conduit. In preferred embodiments, the anchoring portion comprises a locking device such as the Extreme SUR-SET® locking system. However, other anchoring mechanisms may be utilized as well. The blanking plug device has a lower plug portion that incorporates a screening section. The screening section permits flow of fluid through the sidewall of the plug portion while substantially preventing the passage of solid particles.
Claims14
A blanking plug device comprising:
- a plug having an anchoring lock portion for selectively anchoring the plug device within a section of tubing string and a plug portion defining a blind bore within and having a pressure equalization port for transmission of fluid from the exterior of the plug portion to the blind bore;
- and
- a screen associated with the pressure equalization port to substantially prevent transmission of solids through the equalization port.
A system for selectively blanking off pressure within a section of wellbore, comprising:
- a) a plug having an anchoring lock portion for selectively anchoring the plug device within a section of tubing string and a plug portion defining a blind bore within and having a pressure equalization port for transmission of fluid from the exterior of the plug portion to the blind bore, and a screen associated with the pressure equalization port to substantially prevent transmission of solids through the equalization port;
- and
- b) a removable blanking member that is disposable within the blind bore to blank off pressure across the plug.
A method of blanking off pressure within a section of wellbore comprising:
- securing a plug within a section of a wellbore, the plug having a plug portion defining a blind bore within and having a pressure equalization port for transmission of fluid from the exterior of the plug portion to the blind bore;
- filtering fluid transmitted toward the blind bore through the pressure equalization port by passing the fluid through a screen;
- and
- disposing a blanking prong member within the blind bore of the plug to create a fluid seal across the plug.
