Shengli Oilfield R&T Group

First, open wells (from the injection well): Make sure that the production system is completed and that the flow is smooth enough to accept fluids after well opening. All the valves on the Christmas tree oil oilfield are in the correct switch state and can control the nozzle (adjustable nozzle). Check the wellhead hydraulic and safety equipment status. Second, shut the well (since the injection well) Third, in some downhole operations, the operating procedure of the Christmas tree valve is as follows: Close the well (nozzle, wing valve, purge valve, ground relief valve and main valve) before entering the downhole tool. Open the oil tree cap, install the high riser, the blowout preventer, and then test the pressure by the riser. Open the safety valve on the ground, with a fused screw cap on the safety valve to lock the ground safety valve. In the open position, test the reliability of the locking screw cap.   Lock down the hydraulic control circuit of tubing s...

Oil Extraction Wellhead 1. Working pressure: 2000-15000PSI  2. Material grade: AA-FF  3. Normial diameter: 2 9/16″ - 5 1/8″ 4. Temperature grade: LU/PU  5. Specification grade: PSL1-PSL3 6. Performance grade: PR1/PR2 Wellhead equipment and Christmas tree are essential for oil and gas exploitation, compassed of casing head, tubing head and Christmas tree, used to connect casing string and tubing string, and seal the annular spaces between all casing at all layers and between pipelines.
