Abstract
During a production of hydrocarbons a method and a device are used for producing a flow of hydrocarbon-containing formation fluid from a formation at a bottomhole of a well, automatically maintaining a pressure of the formation fluid at the bottomhole of the well at a level sufficient for maintaining an optimum flow of the formation fluid from the formation at the bottomhole of the well towards a wellhead by changing a parameter of a flow passage of an automatically maintaining unit arranged in the well in response to changes in properties of the formation and formation fluid, and performing the changing of the parameter of the flow passage of the automatic maintaining unit in response to a difference of a formation fluid flow parameter upstream and downstream of the automatic maintaining means.
