Abstract

A test sub having a housing with a first end, a second end, a bore, and an exterior portion of the housing including a coiled tubing connector may be used to test a connection with coiled tubing. The test sub includes a valve positioned within the bore. The second end of the housing may be inserted into coiled tubing and fluid may be pumped into the housing to test the connection between the connector and the coiled tubing. The test sub may be a housing that may be attached to a coiled tubing connector already connected to coiled tubing. A rod within the housing may be moved to an inserted position permitting communication between a pressure port of the housing and an exterior port of the coiled tubing connector. Fluid may be pumped into the pressure port to test the connection between the coiled tubing connector and the coiled tubing.

Claims5

Dependent claims

A system to check a connection between coiled tubing and a coiled tubing connector comprising:

the coiled tubing connector configured to connect to coiled tubing, the coiled tubing connector having a bore, a first sealing element, a second sealing element, and an exterior port in communication with the bore, the exterior port being positioned between the first sealing element and the second sealing element;
a housing configured to be sealingly attached to an end of the coiled tubing connector, the housing including a bore in communication with the bore of the coiled tubing connector when attached, a movable rod positioned within the bore of the housing, and a pressure port in communication with the bore of the housing;
wherein the moveable rod is configured to extend into the bore of the coiled tubing connector, the rod being movable from an extended position to an inserted position;
wherein a seal at an end of the rod engages the bore of the coiled tubing connector;
wherein in the extended position the seal at the end of the rod prevents communication from the pressure port of the housing to the exterior port of the coiled tubing connector;
and
wherein in the inserted position the seal at the end of the rod permits communication between the pressure port of the housing and the exterior port of the coiled tubing connector.
