ABSTRACT:
The invention refers to a device for the continuous gas-lift exploitation of petroleum deposits by means of a depression effect and of a gas-dynamic pulverization. The device according to the invention, consists of a cylindrical adapting piece in which a threaded sleeve is screwed, coupled, in its turn, with a male union provided at its upper end with a profiled wall which, together with the cylindrical adapting piece, shapes a straight depressionary baffle, the profiled part having a curved profiled wall which, together with the profiled wall of the male union, shapes a peripherical annular slot. The nozzle consists of the baffle and slot whose dimensions can be modified as a function of the production depth by dimensionally modifying the profiled part. The slot communicates with an equalization chamber, circumferentially provided with some apertures for the supply of lift gases. Erosion reduction of parts is achieved by means of a protective coating of metallic oxides. The device is mounted on the pipe string.
