A fluid injection device () for controlling injection of fluid into an oil-carrying tube in an oil well includes an inlet () for receiving the fluid; an outlet () for supplying the fluid for injection into the oil-carrying tube; an inlet valve () in a fluid path between the inlet and the outlet; an actuator () for opening and closing the valve; and a connector () for coupling the inlet to a fluid supply tube () extending between the device and a source of the fluid above the ground. A method of controlling injection of fluid using such a device is also provided.

Fluid injection device

A fluid injection device () for deployment in a well-bore to control injection of fluid into an oil reservoir, wherein the well-bore has an outer pipe () and an inner tube () which extends within the outer pipe and is connected at one end to a pressurized fluid supply above the ground. The device includes a control valve arrangement comprising: an inlet () for receiving the fluid from the inner tube; an outlet () for outputting the fluid outside the inner tube; an inlet valve () in a fluid path between the inlet and the outlet; and an actuator () associated with the inlet valve which is controllable to switch the inlet valve between its open and closed configurations, such that when the inlet valve is open, the fluid flows from the inner tube, via the inlet, fluid path and outlet to outside the inner tube. A method of controlling injection of fluid into an oil reservoir from a well-bore using such a device is also provided.
