Abstract
The utility model relates to an injection process tubular column of an inverted submersible pump, which comprises an oil pipe, a compensator, a motor upper packer, a discharge port, a centrifugal pumplower packer and a suction port, and is characterized in that the compensator, the motor, the packers, the discharge port, a centrifugal pump and the suction port are subsequently connected with theoil pipe in a sleeve to form the process tubular column of extracting downwards and injecting upwards. The injection process tubular column of the inverted submersible pump is characterized by the omission of injection station, pipe network and water treatment, resource saving and the like, and is widely applied to the oil production process of oil fields.
Description
One, technical field
The utility model relates to petroleum production water injection technology device, specifically a kind of inversion submersible electric pump water injection technology tubing string.
Two, background technique
Traditional oil field block water filling is used basically and is built water flooding pump station, take the form of pipe network water filling by water injection string, use the produced-water reinjection of water supply well or processing station, this water injecting device is that the water injection technology of petroleum production contributes, but also there are following shortcoming or deficiency simultaneously: 1. for the water injection well that water layer is arranged itself, this water flooding regime is a kind of waste, does not effectively utilize the resource of water injection well; 2. owing to build water-injection station, the engineerings such as laying of water treatment field maintenance, waterflood-transmission line cause the water filling cost too high.
Three, summary of the invention
The technical problems to be solved in the utility model is to overcome and avoid the shortcoming and defect that exists in the above-mentioned prior art and a kind of inversion submersible electric pump water injection technology tubing string is provided.
Inversion submersible electric pump water injection technology tubing string described in the utility model, comprise oil pipe, compensator, motor upper packer, exhaust port, centrifugal pump lower packet and suction port, it is characterized in that described compensator, motor, packet, exhaust port, centrifugal pump and suction port are connected on the interior oil pipe of sleeve pipe in turn, constitute and adopting the upward process pipe string of making a bet.
Wherein, described upper packer is positioned on the implanted layer, and lower packet is positioned to be adopted on the water layer.Described exhaust port is positioned at the implanted layer place, and suction port is positioned at the industry water layer and goes into.Described compensator, motor, lower packet, suction port, centrifugal pump, upper packer and exhaust port are installed and connected on the interior oil pipe of magnetic tube in turn, constitute to adopt to pour down process pipe string.
The utility model has following advantage compared with prior art:
1, owing to adopt this well water layer water to carry out water filling, problems such as surface water treatment device, surface line laying, ground installation maintenance have been saved, cost saving.
When 2, developing some low, little, difficult, inclined to one side blocks and oil reservoir, above-mentioned water injection technology has very high practicality and economic value because realization is easy, field maintenance is simple.
Four, description of drawings
Fig. 1 is a kind of upward process pipe string schematic representation of making a bet of adopting of the present utility model
Fig. 2 adopts for another kind of the present utility model and pours down the process pipe string schematic representation
Five, embodiment:
Consult Fig. 1-Fig. 2, a kind of inversion submersible electric pump water injection technology tubing string comprises oil pipe, compensator, motor upper packer, exhaust port, centrifugal pump lower packet and suction port.Compensator 2, motor 3, packet 4,8 exhaust ports 6, centrifugal pump 7 and suction port 10 are connected on the oil pipe 1 in the sleeve pipe 11 in turn, constitute that adopting makes a bet goes up process pipe string, as Fig. 1.
As Fig. 2, compensator 2, motor 3, packet 8, suction port 10, centrifugal pump 7, packet 4 and exhaust port 6 are installed and connected on the oil pipe 1 in the sleeve pipe 11 in turn, constitute to adopt to pour down process pipe string.
During operation, the liquid that water layer 9 is adopted on packet 4 tops is extracted in 7 work of oil-submersible motor driving multistage centrifugal pump, enters multistage centrifugal pump 7 through suction port 10, and supercharging is injected the implanted layer 5 of packet 4 bottoms after exhaust port 6 is discharged, and realization is adopted with well and poured down.Otherwise realize with well adopt make a bet on.
