摘要： Hydrocarbons are produced from a well having a bottomhole and a wellhead and communicating with a formation, by producing a flow of hydrocarbon-containing formation fluid from the formation at the bottomhole of the well, transforming the flow of the formation fluid from the formation at the 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 liberated gas is formed in the well between the location of the transformation and the wellhead, and automatically maintaining a pressure of the formation fluid at the bottomhole in the well higher than saturation pressure, substantially independently from changes in properties of formation and formation fluid.

摘要： A method of production of the formation fluid is used in wells with a low formation pressure and consists in that in the well from a flow of the formation fluid forcedly liberated is the gas dissolved therein and then the formation fluid is transformed into a finely dispersed gas-liquid flow in which the amount of liberated gas ensures self-lift of the formation fluid to the wellhead. A device, effecting this method, comprises a body hermetically secured in the well string, a nozzle and Venturi tubes. The Venturi tubes are installed over the nozzle, coaxially with it, and each below-positioned tube serves as a nozzle for the above-positioned one.

摘要： 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.
