摘要

A tubing hanger apparatus includes a tubing hanger with a plurality ofsegmentsthereon that engage an annular groove of a tubing head thus preventing thetubing hangerfrom sliding down a well. The internal diameter wellhead bore is consistentfrom themaster valve downward to the production casing. The tubing hanger has aplurality ofannular seats which are expandable after insertion into the tubing head. Aplurality oflock screws both expand the seals as well as prevent any further movement ofthe tubinghanger. The tubing hanger apparatus is situated below a master valve. Thus,coiledtubing or jointed tubing ean be ran down the well and landed below the mastervalve.The tubing hanger contains a back pressure valve, thus the master valve can beopenedwithout releasing the formation pressure within the live well.
