Abstract
A coiled tubing connection system is used in a well. A connector having an engagement end is used to couple a wellbore device to the end of a coiled tubing. The connector is spoolable, and the engagement end comprises engagement features that facilitate formation of a connection that is dependable and less susceptible to separation.
Claims11
A method of forming a flow-through connection with a coiled tubing, comprising:
- swaging an end of the coiled tubing at a well site to form a round connection end;
- providing a thread cutting tool to the well site;
- cutting a thread pattern into the round connection end at the well site with the thread cutting tool;
- and
- threadably engaging a connector with the round connection end while at the well site, the connector having an engagement end comprising a corresponding thread pattern, the connector defining a hollow interior therein for conducting well fluids therethrough.
2 more elements
A system for forming a coiled tubing connection at the well site, comprising:
- a coiled tubing having an end threaded with an interfering thread;
- a connector having an engagement end with a corresponding interfering thread, wherein threadably engaging the corresponding interfering thread and the interfering thread creates a sacrificial threaded connection to prevent the connector from being released from the coiled tubing;
- and
- a wellbore device coupled to the coiled tubing by the connector, the connector further defining a hollow interior and wherein the wellbore device is operable to receive flow through the coiled tubing and the connector.
