It is the most advanced tubular running service in the world., which is provided by a specialized team. Through the special equipment and instruments, professional technical talents and strict technical standards, we accurately monitor the torque of oil/casing upper buckling, etc. The technology has the advantages of no harm to the special steel oil casing, optimal torque control of oil casing upper buckling, reliable sealing of upper buckling, etc., which can ensure the safe and environmentally friendly production of special oil and gas wells, extend the service life of tubular column, and save the development cost, such as the production of high-pressure, high-temperature and high-sulfur wells. This technology has the advantages of no harm to special steel oil casing, optimal torque control of oil casing snap-on, reliable snap-on sealing, etc., which can ensure the safe and environmentally friendly production of high pressure/high temperature/high sulfur content oil and gas wells, extend the service life of tubing column, and save the development cost.
