Common wellhead and Christmas tree
Production tree is a kind of wellhead device used for producing oil (gas) and testing oil and gas after completion of flowing wells and mechanical production wells. It is the main equipment for controlling and regulating oil and gas production at the top of oil and gas wells. It can be used to hang tubing and running tools, support the weight of all tubing strings in the well, seal the annular space between tubing and casing, control and adjust the production of oil wells, ensure the downhole operation construction, facilitate the construction of well killing operation, tripping operation and other measures, and carry out daily production management such as pressure measurement and wax removal, and record the data of oil pressure and casing pressure. Among them, tubing head, hanger, valve and other parts adopt standard configuration, and users can customize oil (gas) tree with standard configuration according to specification requirements and casing program.
