摘要： A tool for selectively treating a wellbore with fluid that includes a tubing string having a sidewall defining an inner bore, the sidewall comprising a flow area having at least one fluid flow port that permits fluid flow through the sidewall. Fluid is prevented from flowing through the flow area when a closure is in a closed position. When in the open position, fluid flows through the flow area. An axial seal is connected to the closure to selectively close the inner bore against fluid pressure to apply the predetermined opening force to move the closure to the open position. A releasable connector connects the axial seal to the closure and a retrieval tool attachment releases the axial seal from the closure upon application of a predetermined release force by a retrieval tool.

摘要： An enclosed circulation tool for a well including a tubular body having a top end, a bottom end and an interior cavity. A progressive cavity pump positioned at the bottom end of the body, the pump having a rotor mounted within a stator. The rotor has an upper end and a lower end, with the upper end extending into the interior cavity. A drive is coupled to and adapted to rotate the rotor in order to draw sand into the interior cavity. A first fluid passage is provided along which fluids from pumped from surface pass to fluidize solids within the interior cavity. A second fluid passage is provided along which fluidized solids from within the interior cavity pass to surface.
