For production of hydrocarbons from a hydrocarbon formation through a well in a condition of fluctuations in the formation pressure, in addition to transformation of a formation fluid into a gas-liquid flow, the bottomhole pressure is automatically regulated at a level higher than saturation pressure of the formation fluid, regardless of any changes in properties of the formation and the formation fluid. At the same time, the speed of the flow of the formation fluid from the bottomhole to a location of transformation is maintained automatically at a level to be sufficient for the transformation of the formation fluid into the gas-liquid flow.

[ What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims:] [1.] A method of production of hydrocarbons from a well having a bottomhole and a wellhead and communicating with a formation, the method comprising the steps of producing a flow of hydrocarbon-containing formation fluid from the formation at the bottomhole of the well; transforming the flow of the formation fluid at a location of transformation into a finely-dispersed gas-liquid flow with a liberated gas forming a part of the gas-liquid flow, so that a column of the formation fluid is formed in the well from the depth of the formation to the location of transformation, and a column of the finely-dispersed gas-liquid flow with a liberaged gas is formed in the well between the location of transformation and the wellhead; and additionally, in response to a pressure drop of the formation fluid automatically reducing a flow cross-section and increasing a speed of the flow of the formation fluid, and in response to a pressure increase of the formation fluid, automatically increasing a flow cross section and decreasing the speed of the flow of the formation fluid, thereby automatically maintaining a pressure of the formation fluid at the bottomhole in the well higher than saturation pressure, substantially independently from any changes in properties of the formation and the formation fluid.
