摘要：An injection manifold for use in injecting fluid into a well and method of use. Several embodiments of the apparatus are shown. In each embodiment, a bypass valve is used to control the discharge pressure of a pump, and a throttling valve is used to control the fluid injection flow rate to the well in response to a flow rate measured by a flow meter. In a first embodiment, the throttling is carried out manually. In a second embodiment, the throttling is carried out automatically by a controller which compares a flow rate signal from the meter with a predetermined flow rate set point and sends a corresponding output signal to an actuator of the throttling valve. A third embodiment is a combination manifold which may also be used for flowback tests from the well. In this third embodiment, the electronic controller may also be used to control the flow rate during the flowback test in response to a flow rate signal from the flow meter. A method of injecting fluid into a well using the apparatus is also disclosed.
