Description
Technical field
The utility model relates to flow string, specifically the two electric pump flow strings in a kind of down-hole.
Background technology
Electric submersible pump is the main artificial lifting way of offshore oilfield, offshore oilfield exploitation both at home and abroad is many based on single electric submersible pump at present, because the life-span of electric pump equipment self and the pump efficiency step-down that reservoir condition changes and causes cause the oil well output loss, pump detection period shortens.At this problem, the two electric pump flow strings in a kind of down-hole in the utility model patent, have been invented.
Summary of the invention
The purpose of this utility model is to provide a kind of down-hole two electric pump flow strings, not only can realize the oil recovery phase of long period, prolongs the life-span of electric submersible pump, reduces the operation number of times, and environmental, reduces and pollutes.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, the two electric pump flow strings in a kind of down-hole, comprise sleeve pipe and the interior oil pipe of sleeve pipe in the producing well, described oil pipe lower end connects flow string, two cover electric pumps are installed on the described flow string, are respectively electric pump and following electric pump, and two electric pumps are installed in layer positions different in the same oil well with parallel way.
Be provided with packer between the oil pipe of described oil reservoir top position and the sleeve pipe.
Described flow string upper and lower side is provided with and is located joint, is respectively and is located joint, is located joint down, and described flow string is connected the oil pipe lower end by being located joint on the upper end.
The described electric pump of going up is connected on the production tube by last breeches joint, and the described electric pump of going up also is connected with double and single flow valve.
Described electric pump down is connected on the production tube by following breeches joint, and described electric pump down also is connected with double and single flow valve.
Also be provided with sliding sleeve on the described flow string, sliding sleeve is positioned on the flow string of electric pump top position.
Describedly go up electric pump and following electric pump all are connected ground by cable power supply.
Described oil pipe lower end is fixed in the sleeve pipe by tubing hanger.
Compared to prior art, the utlity model has following beneficial effect:
Characteristics of the present utility model: 1, service life as compared conventional 1 electric submersible pump raising at present is more than 1 times; 2, can dispose the electric submersible pump of different displacements and lift according to changes in reservoir, reduce because the production loss of adopting a cover electric submersible pump to cause; 3, in Y joint tubing string, design the double and single flow valve body, adopted the ball-and-seat series connection structure, improved reverse sealing effectiveness.
Description of drawings
Fig. 1 is the two electric pump flow string structural representations in a kind of down-hole of the present utility model.
Among the figure: 1, tubing hanger; 2, packer; 3, be located joint on; 4, sliding sleeve; 5, go up breeches joint; 6, double and single flow valve; 7, go up electric pump; 8, following breeches joint; 9, following electric pump; 10, be located joint down.
The specific embodiment
Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however accompanying drawing only provides the usefulness of reference with explanation, and the utility model is limited.
With reference to accompanying drawing 1, the two electric pump flow strings in a kind of down-hole, comprise sleeve pipe and the interior oil pipe of sleeve pipe in the producing well, described oil pipe lower end connects flow string, install electric pump 7 and following electric pump 9 on the described flow string, and be installed in different layers position in the same oil well with parallel way, and share 1 oil pipe and recover the oil, can enable 2 cover unit assemblies sequentially.Be provided with packer 2 between oil pipe and the sleeve pipe.The flow string upper and lower side is provided with and is located joint, is respectively and is located joint 3, is located joint 10 down, and flow string is connected the oil pipe lower end by being located joint on the upper end.Last electric pump 7 is connected on the production tube by last breeches joint 5, and the described electric pump of going up also is connected with double and single flow valve 6.Following electric pump 9 is connected on the production tube by following breeches joint 8, and described electric pump down also is connected with double and single flow valve.Also be provided with sliding sleeve 4 on the flow string, sliding sleeve is positioned on the flow string of electric pump top position.Describedly go up electric pump and following electric pump all are connected ground by cable power supply.Described oil pipe lower end is fixed in the sleeve pipe by tubing hanger 1.
The utility model has all been installed the double and single flow valve body above the outlet of upper and lower electric pump, this double and single flow valve body has good reverse sealing performance, thereby has avoided the refluence phenomenon.When diving pump operation when powering on, the double and single flow valve body sealing of following electric submersible pump top is the electric submersible pump branch road down, and the following blanking plug of installing on the following electric submersible pump bypass pipe that is located joint cuts out, and seals this bypass branch road.During electric submersible pump operation instantly, the electric submersible pump branch road is gone up in the double and single flow valve body sealing of last electric submersible pump top, and the following blanking plug of installing on the following electric submersible pump bypass pipe that is located joint cuts out, and seals this bypass branch road.The utility model not only can be realized the oil recovery phase of long period, prolongs the life-span of electric submersible pump, reduces the operation number of times, and environmental, reduces and pollutes, and fairly obvious economic benefit is arranged.
The above only is preferred embodiment of the present utility model, and non-in order to limit claim of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to claim of the present utility model.
