Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of existing electric immersible pump well flow string;
Fig. 2 is the structural representation of a kind of electric immersible pump well flow string among the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 2, the utility model embodiment provides a kind of electric immersible pump well flow string, comprises sleeve pipe, wherein, is provided with in the sleeve pipe 4:
Oil pipe 2 is fixed in the sleeve pipe 4 by the tubing hanger 1 that is arranged at sleeve pipe 4 tops;
The first Y-shaped connector 5 is arranged at the below of tubing hanger 1, and with screwed connection on oil pipe 2;
The second Y-shaped connector 7 is arranged at the below of the first Y-shaped connector 5, and with screwed connection on oil pipe 2, the inside of the oil pipe 2 between the first Y-shaped connector 5 and the second Y-shaped connector 7 is provided with Y stifled 6;
Between the first Y-shaped connector 5 and the second Y-shaped connector 7, direction along the first Y-shaped connector 5 to second Y-shaped connectors 7 is sequentially provided with electric pump 8, eliminator 15, protector 17 and the motor 16 that connects in turn, the inlet opening of eliminator 15, protector 17 and motor 16 are surrounded by kuppe 14, wherein, electric pump 8 is communicated with oil pipe 2 by the first pipeline 31 that passes the first Y-shaped connector 5, and kuppe 14 is communicated with oil pipe 2 by the second pipeline 32 that passes the second Y-shaped connector 7;
Be provided with circulation slide sleeve 13 (or unidirectional logical inverse well-flushing valve) on the oil pipe 2 of the second Y-shaped connector 7 belows;
Be provided with safety valve 10 on the oil pipe 2 of circulation slide sleeve 13 (or unidirectional logical inverse well-flushing valve) below;
