The above patent provides an integral Christmas tree, the casing and the production pipe are fixedly connected to the Christmas tree body through a connecting flange, which is convenient for maintenance, a screw sleeve is arranged on the inner side of the fixing plate, which is convenient for the Christmas tree body to be more tightly connected to the ground, and a sealing gasket is arranged at the connection between the casing and the production pipe and the Christmas tree body, which is convenient for ensuring the sealing of the whole device, and four shock absorbing mechanisms are arranged, which is convenient for buffering and protecting the Christmas tree body, and an anti-slip plate is arranged at the bottom of the movable rod, and a through groove matched with the anti-slip plate is arranged on the lower side of the fixing plate, which is convenient for ensuring the buffering of the whole device.

[0004] The temperature of crude oil is generally 20-40 degrees during extraction. As the crude oil gradually rises along the pipeline to the ground, the temperature of the crude oil also gradually decreases. For some oil extraction sites with lower temperatures, if the temperature of the crude oil is too low, it is easy for the crude oil to be frozen inside the oil tree and cannot be discharged.
