The newly developed surge-type over-the-air logging blowout preventer is composed of 5 parts of logging booster, anti-spout tube, pulley block, donkey head support and lifting winch. The utility model has the advantages of simple structure and convenient operation and the like; Most oil wells, especially those with liquid level at the well head, can conduct closed well logging successfully with a success rate of 83%. It can also overcome the limitation of the wellsite environment and carry out construction without a derrick and save direct investment. The on-site Experiments show that the application of this device can improve the sealing rate of annulus logging and provide a guarantee for accurate annihilation logging data
