Wellhead Christmas
Tree
In oil and gas extraction,
oil recovery trees or "trees" are a combination of valves, casing tetrads and fittings used to regulate pipe flow in oil wells, gas wells, water injection wells, water treatment wells, gas
injection wells, condensate wells and other types of wells.
Product Description
Wellhead and Christmas tree equipment is an important equipment of
oil and gas drilling, the casing head, tubing head, and oil (gas) tree of three parts, used to connect the casing string and tubing string, and the sealing between the layers of casing and tubing
annulus, and can control the production wellhead pressure and adjust the oil (gas) wellhead flow, also can be used in acid fracturing, injection, testing and other special operations.
Wellhead devices and trees
can be divided into oil production wellhead devices, gas recovery wellhead devices, fracturing and acidification wellhead devices, thermal recovery wellhead devices, and other wellhead devices.
The Wellhead devices and tree is mainly assembled by a gate valve, throttle valve, three-way, four-way, plug valve emergency cut-off valve and other pressure components.
