摘要： The invention is a downhole valve that includes a body, a flow tube assembly that includes an upper tube member and a lower tube member, and a flapper valve. The flapper valve is pivotally attached to the body and is positioned between the upper tube member and the lower tube member when the flapper valve is in a closed position that blocks fluid flow in an internal bore of the body. The flapper valve is moved from the closed position to an open position in response to an upward movement of the upper tube member and the lower tube member. When the flapper valve pivots to the open position, the lower tube member moves adjacent to and forms a seal with the upper tube member, forming an unobstructed internal bore.

摘要： An apparatus and method for controlling the fluid flow in a wellbore provides a side pocket mandrel having a main bore, an offset bore, and a radial passageway providing communication therebetween. Inlet orifices through the outer wall of the mandrel provide fluid communication between the offset bore and an exterior of the mandrel. A choke, or valve, attached to the mandrel is adjustable at and between an opened and closed position to control the flow rate through the inlet orifices and into the offset bore. The radial passageway and the inlet orifices are sized to provide full bore flow into the main bore and, thus, the tubing. Well tools may be positioned in the offset bore to perform various functions. Examples of such well tools include a seal bore protector adapted to protect the walls of the offset bore; an injection valve adapted to allow flow out of the mandrel only to facilitate injection into the formation; and a pack off valve adapted to seal the offset bore and prevent fluid flow therethrough.
