Е 21 В 33/14, 1959. that air, attached to one atmosphere-ture, must be equal to the volume of that part of the annular space, by which the x-quantity of the squeezing fluid decreases. When cementing an abscess with a rise in the cement slurry, but after hardening the cement slurry, in the Second Stage, the missing amount of cement slurry is pumped into the open annular space. The method allows for the drilling of oil and gas squalines to significantly increase the efficiency of well construction. The formula of the invention The method of cementing a casing string in a well in the presence of absorbing plates by forcing a cement mortar in the annular fluid space, is due to the fact that, in order to save the time of the process in improving the quality of cementing, at the time of equilibrating the column of cement solution and the fragrant fluid with plugut pressure, pushing the pipe by compressed air to the depth of the static fluid pumped into the annulus.
