Specific embodiment
The utility model is made with reference to Fig. 1.A kind of hypotonic stripper well gas-drive oil-production apparatus, including PLC control cabinet
1st, air compressor machine 2, flowline 3, production tree 7, wellhead sealing lid 6, oil pipe 8 and casing 13, PLC control cabinet 1 pass through conducting wire and pneumatics
Machine 2 connects, and the working condition of air compressor machine 2 is controlled by PLC control cabinet 1, and production tree 7 is fixed on the well head of oil well, adopts
The oil outlet of oil tree 7 is equipped with flowline 3, and the central through hole of production tree 7 is equipped with wellhead sealing lid 6, casing is equipped in oil well
13 and oil pipe 8, oil pipe 8 be located at 13 intracavitary of casing, it is characterised in that：The upper end of oil pipe 8 and the fixed company of 7 lower end of production tree sealing
It connects, the lower end of oil pipe 8 is fixed with plugging plate, and plugging plate is equipped in line check valve 12, in being equipped in the intracavitary bottom of oil pipe 8
Heart pipe 9, is fixed with sealing ring 10 between the lower end outer wall of central tube 9 and the inner wall of oil pipe 8, sealing ring 10 is equipped with out
Oily check valve 11, the lower mouth of the suitable for reading and communicating pipe 14 of central tube 9 are connected, and the upper end of communicating pipe 14 passes through wellhead sealing lid 6
