Abstract
Fluid injection tools for use in a wellbore can be configured on-site prior to run-in and can be opened or closed on demand when positioned in the well. A fluid injection tool can be used to provide steam to a wellbore annulus during a steam assisted gravity drainage procedure. Nozzles in the tool through which the steam escapes can be individually plugged to enable fine-tuning of steam output to match a desired steam output for that particular tool's location within the wellbore. A sliding side door can be actuated, such as by a shifting tool inserted within the inner diameter of the fluid injection tool, to enable or disable steam output from the fluid injection tool.
Claims16
A fluid injection tool comprising:
- an accumulation chamber in fluid communication with a plurality of nozzles within a first housing, wherein a first nozzle of the plurality of nozzles has a first inner diameter and a second nozzle of the plurality of nozzles has a second inner diameter that is different than the first inner diameter, and the first nozzle and second nozzle are individually pluggable;
- a tubular having an orifice for communicating a fluid between an inner diameter of the fluid injection tool and the accumulation chamber;
- at least one diffuser in fluid communication with the plurality of nozzles, the at least one diffuser comprising an opening formed from or within the first housing and being positioned opposite the accumulation chamber from the plurality of nozzles.
A method, comprising:
- supplying fluid to an accumulation chamber of a fluid injection tool through at least one orifice from an inner diameter of the fluid injection tool;
- directing the fluid to a plurality of nozzles fluidly connected to the accumulation chamber, wherein a first nozzle of the plurality of nozzles has a first inner diameter and a second nozzle of the plurality of nozzles has a second inner diameter that is different than the first inner diameter, and the first nozzle and second nozzle are individually pluggable;
- and
- directing the fluid from at least a first subset of the plurality of nozzles through one or more open shapes in fluid communication with the plurality of nozzles.
A fluid injection tool comprising:
- an accumulation chamber in fluid communication with a plurality of nozzles, at least a first nozzle and a second nozzle of the plurality of nozzles being individually pluggable and positioned to communicate steam axially in both directions along an annulus formed between the fluid injection tool and a casing or wellbore, and wherein the first nozzle has a first inner diameter and the second nozzle has a second inner diameter that is different than the first inner diameter;
- a tubular having an orifice for communicating a fluid between an inner diameter of the fluid injection tool and the accumulation chamber;
- and
- a plug positionable in at least one of the plurality of nozzles that at least partially restricts flow of the fluid out of the fluid injection tool.
