Abstract
An adjustable fluid injection tool for use in a wellbore may be used to provide steam to a wellbore annulus. The tool may be adjusted immediately before being positioned in a well. Fluid may exit an inner space of the tool into an accumulation chamber, after which the fluid may exit the tool through one or more adjustable valves. An adjustable valve may be formed between a valve seat of a shroud and a valve plug of a plug sleeve. The plug sleeve may be positioned around a tubular of the tool and able to translate linearly with respect to the shroud by rotating the plug sleeve, thus adjusting the adjustable valve and controlling fluid flow out of the tool.
Claims17
A fluid injection tool comprising:
- an injection housing comprising a first set of threads;
- a shroud positioned about the injection housing and defining an accumulation chamber between the shroud and the injection housing, wherein the injection housing includes an orifice fluidly connecting an inner diameter of the injection housing to the accumulation chamber;
- and
- an adjustable valve fluidly coupled to the accumulation chamber for controlling fluid flow through the accumulation chamber, the adjustable valve comprising:
- a plug sleeve comprising a second set of threads threadedly engaged with the first set of threads of the injection housing, wherein the plug sleeve is rotatable about a central longitudinal axis of the injection housing to linearly translate a valve plug coupled to the plug sleeve toward or away from a valve seat coupled to the shroud to throttle the fluid flow.
A method, comprising:
- supplying fluid to an injection housing comprising a first set of threads;
- directing fluid, through an orifice of the injection housing, to an accumulation chamber formed between the injection housing and a shroud positioned about the injection housing;
- and
- throttling fluid flow through the accumulation chamber by an adjustable valve comprising a plug sleeve, the plug sleeve comprising a second set of threads threadedly engaged with the first set of threads of the injection housing, wherein the plug sleeve is rotatable about a central longitudinal axis of the injection housing to linearly translate a valve plug coupled to the plug sleeve toward or away from a valve seat coupled to the shroud to throttle the fluid flow.
A fluid injection tool, comprising:
- an injection housing having an inner diameter and a first set of threads;
- a shroud coupled to the injection housing;
- a plug sleeve positioned between the injection housing and the shroud, wherein the plug sleeve comprises a second set of threads threadedly engaged with the first set of threads;
- an adjustable valve comprising a valve seat and a valve plug, wherein the valve seat is coupled to the shroud, and wherein the valve plug is coupled to the plug sleeve;
- and
- an accumulation chamber defined by the shroud, the injection housing, and the adjustable valve, wherein the accumulation chamber is fluidly coupled to the inner diameter of the injection housing through an orifice in the injection housing, and wherein the plug sleeve is rotatable about a central longitudinal axis of the injection housing to linearly translate the valve plug toward or away from the valve seat to throttle fluid flow through the accumulation chamber.
