Thermal recovery wellhead equipment

The thermal recovery wellhead unit (thermal recovery tree) is the core surface control equipment for the thermal recovery of heavy and extra-heavy oil. It is designed in accordance with SY/T 5328-2019 and API 6A standards and is mainly used for steam injection, steam drive, SAGD steam-assisted gravity drainage, multi-element thermal fluid, fire drive and other processes. It realizes high temperature and high pressure steam injection, crude oil production, annular pressure monitoring, and downhole operation safety management and is adapted to extreme working conditions of repeated hot and cold cycles.
