Accompanying drawing explanation
Fig. 1 is pit shaft-pipeline self energy wax removal integrated apparatus structural principle block diagram of heating.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, the well head gas production device 19 that pit shaft-pipeline self energy is heated on wax removal integrated apparatus is connected well mouth of oil well production tree 12 by No. 1 valve 13 of gas production device inlet valve 15 and well head, the gas that well head gas production device 19 gathers enters primary separator 8 by primary separator admission valve 10 and carries out gas-liquid first separation, associated gas after primary separator 8 separation enters second-stage separator 6 by primary separator air outlet valve 9 and second-stage separator admission valve 20 and carries out secondary separation, one, the liquid that second-stage separator is separated is collected by tapping valve 7, the associated gas of second-stage separator 6 separating treatment supplies fuel gas generation unit 4 by unit admission valve 5.
Liquid after well head gas production device 19 collection gases enters mi heater device 1 by heater inlet valve 22 and heats, and is wound around mi heater line 2 on the coil pipe of mi heater device 1, and the liquid after heating flows out by heater outlet valve 23.
