Abstract
A fluid injection device (18) for controlling injection of fluid into an oil-carrying tube in an oil well includes an inlet (20) for receiving the fluid; an outlet (28) for supplying the fluid for injection into the oil-carrying tube; an inlet valve (22) in a fluid path between the inlet and the outlet; an actuator (24) for opening and closing the valve; and a connector (36) for coupling the inlet to a fluid supply tube (32) 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.
Claims16
A fluid injection device for controlling injection of fluid into an oil-carrying tube in an oil well, the device including:
- 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 into an oil-carrying tube in an oil well, comprising the steps of:
- providing a fluid injection device of any preceding claim;
- coupling the connector to a fluid supply tube extending between the device and a source of the fluid above the ground;
- and
- selectively operating the actuator so as to inject the fluid into the oil-carrying tube via the outlet.
