Abstract
The utility model relates to the technical field of super heavy oil deposit fireflooding, in particular to a fireflooding double-pipe shaft mouth oil extraction pipe column. A double-pipe shaft mouth device of the oil extraction pipe column comprises an upper flange, a sucker rod sealer, a double-pipe hanging device, a large four-way joint, sleeve valves, oil pipe valves, an oil mixing valve and a testing valve, wherein the oil extraction pipe column and a thin oil mixing pipe column are hung on the double-pipe hanging device, the oil extraction pipe column comprises an oil pipe, a sucker rod and an oil-well pump, the thin oil mixing pipe column comprises an oil pipe, the lower end of the oil pipe is connected with a guide shoe, and the upper end of the thin oil mixing pipe column is communicated with the oil mixing valve and the testing valve. The fireflooding double-pipe shaft mouth oil extraction pipe column enables thin oil mixing of an oil shaft and sleeve exhaust gas emission to be carried out at the same time, does not affect fireflooding development effects, and can carry out annulus logging and working fluid level monitoring on oil sleeve annular space. The defects that an existing oil extraction pipe column cannot carry out sleeve exhaust gas emission when thin oil is mixed in the oil sleeve annular space and affects the fireflooding development effects are overcome.
Description
Technical field:
The utility model relates to a kind of super-heavy oil deposit fire flood technical field, particularly the two-tube well head flow string of a kind of fire flood.
Background technology:
Oilfield fireflood oil recovery producing well generally adopts the conventional oil recovery mode of production at present, namely by the flow string with downhole pump crude oil is lifted to ground, sleeve pipe is discharged tail gas, but for the super-heavy oil deposit fire flood, since the initial stage of production adopt the steam soak mode to exploit, production fluid is moisture viscous crude, present emulsification shape or suspension under certain condition, viscosity obviously increases, have to mix thin oil or surface activity liquid reaches the reduction Crude viscosity by oil sets annular space, so just can not implement the discharging of sleeve pipe tail gas, cause casing pressure to raise, oil well liquid level descends, this not only causes the oil extraction pump pump efficiency to descend or inhales less than oil, and makes oil well mix thin oil can not mix the oil well pump overload, cause rod parting, and then affect the development effectiveness of fire flood.
The utility model content:
The technical problems to be solved in the utility model provides the two-tube well head flow string of a kind of fire flood, this device has realized that oil well is mixed thin oil and the sleeve pipe exhaust emissions can carry out simultaneously, do not affect the development effectiveness of fire flood, and can carry out annulus logging and producing fluid level monitoring to oil sets annular space.Overcome existing flow string and when oil sets annular space is mixed thin oil, can not implement the discharging of sleeve pipe tail gas, affected the deficiency of the development effectiveness of fire flood.
Technical solution adopted in the utility model is: the two-tube well head flow string of a kind of fire flood comprises dual tubing wellhead; Dual tubing wellhead comprises upper flange, pumping rod sealer, dual tubing hanger, big four, sleeve valve, tubing valve, mix oil valve and test valve, be hung with flow string on the dual tubing hanger and mix the thin oil tubing string, flow string comprises oil pipe, sucker rod and oil well pump, mix the thin oil tubing string and comprise oil pipe, the oil pipe lower end connects guide shoe, mixes thin oil tubing string upper end and is connected with mix oil valve and test valve.
Mixing thin oil tubing string depth of setting is 500 meters.
The test valve is vertical configuration and is positioned at and mixes thin oil tubing string top, and the test valve communicates with the horizontal valve of mixing oil.
The beneficial effects of the utility model are: the utility model is mixed the thin oil tubing string owing to having adopted, thereby have oil well and mix the function that thin oil and sleeve pipe exhaust emissions can carry out simultaneously, do not affect the development effectiveness of fire flood, and can carry out annulus logging and producing fluid level monitoring to oil sets annular space.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the two-tube well head flow string of a kind of fire flood comprises dual tubing wellhead 1; Dual tubing wellhead 1 comprises upper flange, pumping rod sealer, dual tubing hanger 2, big four, sleeve valve 6, tubing valve 7, mix oil valve 8 and test valve 9, sleeve valve 6 is used for the tail gas that the discharging fire flood produces, tubing valve 7 gives rise to the crude oil in the pit shaft 4 for flow string 3 outlet on ground, the valve 8 of mixing oil is the import that enters pit shaft 4 for mixing thin oil or surface activity liquid, and test valve 9 is used for oil jacket annulus logging and producing fluid level monitoring; Be hung with flow string 3 on the dual tubing hanger 2 and mix thin oil tubing string 5, flow string 3 comprises oil pipe, sucker rod and oil well pump, mix thin oil tubing string 5 and comprise oil pipe, the oil pipe lower end connects guide shoe, mixing thin oil tubing string 5 depth of settings is 500 meters, mix thin oil tubing string 5 upper ends and be connected with mix oil valve 8 and test valve 9, test valve 9 is vertical configuration and is positioned at and mixes thin oil tubing string 5 tops, and test valve 9 communicates with the horizontal valve 8 of mixing oil.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
