Abstract
A stinger is stabbed into a bore opening of a downhole tool to communicate fluid from a fluid line to the downhole tool. The stinger body defines a bore that communicates with the bore opening of the tool when the stinger body is installed in the downhole tool. An external surface of the stinger body can seal and lock inside an inside surface of the tool's bore opening when the stinger body is installed therein. The stinger body has a flow passage connected to the fluid line. A stinger port in the external surface of the stinger body is in communication with the flow passage and positions in fluid communication with a tool port inside the tool's bore opening so fluid can be communicated to the downhole tool.
Claims25
A stinger for communicating fluid between a fluid line and a downhole tool, the downhole tool disposed with tubing, the fluid line running through the tubing, the downhole tool having a tool bore for passage of tubing flow therethrough, the tool bore defining a tool port in an internal surface of the tool bore, the stinger comprising:
- a body having a proximal end and a distal end and defining a body bore for passage of the tubing flow therethrough between the proximal and distal ends,
- the body having a flow passage therein in communication with the fluid line,
- the body having a stinger port in an external surface of the body, the stinger port in communication with the flow passage,
- the body being configured to insert at least partially into the tool bore of the downhole tool,
- the body bore being configured to communicate with the tool bore for the passage of the tubing flow therethrough,
- the stinger port in the external surface being configured to position in fluid communication with the tool port in the internal surface.
A method communicating fluid between a fluid line and a downhole tool disposed with tubing, the downhole tool having a tool bore for passage of tubing flow therethrough, the tool bore defining a tool port in an internal surface of the tool bore, the method comprising:
- connecting a stinger to the fluid line;
- stabbing the stinger in the tool bore of the downhole tool;
- positioning a stinger port in an external surface of the stinger in fluid communication with the tool port in the internal surface of the tool bore;
- communicating the fluid through a flow passage in the stinger between the fluid line and the stinger port in fluid communication with the tool port of the downhole tool;
- and
- permitting the passage of the tubing flow of the tool bore through a stinger bore defined through the stinger.
