Thermal recovery casing head
Thermal recovery casing head is the main component of thermal production wellhead equipment. Firstly, it is used to fix the wellhead of the drilling well and connect the downhole casing string to bear the weight of the blowout preventer; when injecting high-pressure and high-temperature steam into the well, the expansion range of the oil-bearing casing can be reduced; during the disassembly of the wellhead device, the screw thread of the oil-bearing casing near the wellhead can be effectively prevented; when the mud steam flow is released, the annular space between the casings can be effectively sealed to make the mud steam flow Discharge from control discharge nozzle.
