ABSTRACT:
An improved tool for controlling the rate of flow of cement into a well to control the consolidation of a formation is disclosed. The tool comprises a housing, an actuator and a valve member, motion of which is controlled by axial motion of the actuator within the housing. In the preferred embodiment, the valve member includes a fixed size choke orifice which controls the flow of cement into the formation. The tool is operated by lowering it into a well with the valve open, fixing the housing to the casing of the well, pumping cement below the valve, lowering the actuator with respect to the housing to close the valve, and pressurizing the well to force the cement into the formation at a rate controlled by the size of the choke orifice.
