Product Description

API 6A Wellhead Equipment Oil Christmas Tree X-Mass Tree for Oilfield

First, the role of oil harvesting trees

A wellhead device, affectionately known as an 'oil production tree,' is one of the most crucial and prevalent pieces of equipment for oil, gas, and water wells. It serves as the primary apparatus for controlling and regulating the production of oil wells. Its main functions are:

(1) Bearing the weight of all tubing columns and supporting the well;

(2) Sealing the annular space between oil and casing to effectively manage casing gas;

(3) Controlling and modulating the production output of oil wells;

(4) Overseeing daily management, which includes regulating admission oil, setting pressure data, conducting tests, and wax cleaning;

(5) Ensuring the seamless execution of underground operations, such as well washing, sand washing, acidification, and fracturing.

Figure 1-1 illustrates the composition of the wellhead KY65-21 oil production tree.

Second, the types of oil harvesting trees

Oil production trees are classified into two broad categories: traditional and modern. The traditional trees hark back to the 1960s and include iconic models like Dalong (Great Rome replica), Rongfeng (Little Rome replica), and Lianggong (Su replica). The modern category encompasses innovations like Daqing 150, Daqing 160 miniature, Sheng 251, and Sheng II types, all showcasing advancements in design and manufacturing by China.

Third, the structure of oil extraction trees

Taking the domestic KY65-21 oil production tree as an example, its components comprise the casing tee, left/right casing valve, tubing head, tubing tee, general valve, production valves (left/right), test valve or wax cleaning valve (well sealer), tubing top wire, clamp, steel ring, and additional accessories.

Fourth, the connection methods of oil production trees

There are five principal methods for connecting oil trees:

(1) Clamp connection: This method predominantly involves clamping the components of the oil production tree, as seen in models like Daqing 150II, Sheng 261 micro, and Sheng 254;

(2) Thread connection: Components are primarily connected through threading, as exemplified by Daqing 150, Sheng 251, and similar trees;

(3) Iron hoop connection: This method involves using iron hoops to join components, as employed in Sheng I, Sheng II, and comparable trees;

(4) Flange connection: Components are connected using flanges, a method seen in models such as Shanghai Dalong, Rongfeng, and Lianggong;

(5) Clamp flange connection: This hybrid approach uses both clamps and flanges to connect components, notably in the original CY250 and similar oil production trees.
