Hydraulically actuated control fluid communication nipple |
摘要 |
A hydraulic actuated communication nipple for switching control fluid from one location to a second location in a well tool. A body having a longitudinal bore includes a control fluid passageway adapted to be connected to the well surface. A vertical moving sleeve in the body opens communication from the fluid passageway to the bore and is connected to a hydraulic piston in the fluid passageway which includes a bypass opening normally passing fluid through the passageway. A ball dropped down the control line seats on the piston, closes the fluid passage, moves the sleeve, and opens the fluid passageway to the bore. The piston also actuates a vertical moving plug to seal off the outlet with a metal-to-metal seal. A dual communication nipple may be provided which are internally connected by a line to move the fluid displaced by a piston.
