As it is known, gas - lift method is one of the methods used in the exploitation of oil fields. In order to solve practical problems appearing in the gas - lift wells motion equation of gas - liquid mixture moving in the lift should be worked out. In the article the motion equation was obtained and one of the hydrodynamic parameters in the gas - lift wells was appointed as well bottom pressure. In particular, the well bottom pressure in the gas - lift wells was calculated on considering methods and was compared with the measured well bottom pressure. As a result it has been known that, the difference between measured and calculated parameters is acceptable and its application in the mine practice is appropriate.
