Abstract
A hydraulic connection mechanism for use in a wellbore comprises an upper connection tool, a lower connection tool configured to engage the upper connection tool and form a fluid communication pathway through the hydraulic connection mechanism, and a debris barrier disposed in the fluid communication pathway. The debris barrier comprises a body element, and a spring element configured to maintain the body element in a closed position when the upper connection tool is disengaged from the lower connection tool.
Claims21
A hydraulic connection mechanism for use in a wellbore comprising:
- an upper connection tool comprising an upper throughbore, wherein the upper connection tool is configured to be selectively disposed in the wellbore;
- an upper fluid line coupled to the upper connection tool;
- a lower connection tool comprising a lower throughbore;
- a lower fluid line coupled to the lower connection tool, wherein the lower connection tool is configured to selectively engage the upper connection tool and form a fluid communication pathway through the hydraulic connection mechanism between the upper fluid line and the lower fluid line, and wherein the lower connection tool is configured to provide fluid communication between the upper throughbore and the lower throughbore when the lower connection tool is engaged with the upper connection tool;
- and
- a debris barrier disposed in the fluid communication pathway, wherein the debris barrier comprises:
- a body element;
- and
- a spring element configured to maintain the body element in a closed position when the upper connection tool is disengaged from the lower connection tool.
A method of servicing a wellbore comprising:
- providing a hydraulic connection mechanism within a wellbore, wherein the hydraulic connection mechanism comprises:
- an upper connection tool;
- a lower connection tool engaging the upper connection tool, wherein a fluid communication pathway is formed through the hydraulic connection mechanism when the upper connection tool engages the lower connection tool;
- and
- a debris barrier disposed in the fluid communication pathway;
- disengaging the upper connection tool from the lower connection tool, wherein disengaging the upper connection tool comprises removing the upper connection tool from the lower connection tool;
- allowing the debris barrier to close off the fluid communication pathway;
- re-engaging the upper connection tool with the lower connection tool;
- and
- actuating the debris barrier to establish fluid communication through the fluid communication pathway.
A method of actuating a debris barrier comprising:
- engaging an upper connection tool within a throughbore of a lower connection tool within a wellbore, wherein the lower connection tool comprises the debris barrier disposed in a fluid communication pathway within the lower connection tool;
- actuating the debris barrier in response to engaging the upper connection tool within the throughbore;
- displacing a portion of a fluid in the fluid communication pathway into the throughbore in response to the actuating;
- and
- establishing fluid communication between the upper connection tool and the lower connection tool through the fluid communication pathway comprising the debris barrier, wherein the fluid communication pathway is isolated from the throughbore when fluid communication is established between the upper connection tool and the lower connection tool through the fluid communication pathway.
