Abstract
The utility model provides a pneumatic anchoring device for submersible electric-pumps, which is composed of a cylinder body arranged on an electric-pump set, wherein, an annular space formed by the bottom of the cylinder body and a protector is provided with a sealing ring; the cylinder body is above a liquid suction mouth of a centrifugal pump; two half cylinder bodies butt joint to form the cylinder body; the middle part of the cylinder body is provided with a fixing device; the upper part of the cylinder body can be provided with a fixed block. The utility model has the advantages of simple and reasonable structure, convenient installation and operation, and low manufacture cost. The utility model can be effectively applied for machine units used for oil wells which have a plurality of oil to extract oil, and can increase the ratio of oil-gas separation.
Description
The utility model relates to a kind of submersible electric pump gas anchor device of Electric Submersible Pump Unit of oil field machinery oil.
At present, in crude oil exploitation, down to the shaft bottom, the rotation by motor drives its top and connects the multistage centrifugal pump of establishing, and missile silo liquid is risen on the ground the electric pump unit.When the contained gas of well liquid more for a long time, centrifugal pump is easily by gas attack, and causes the whole unit can't proper functioning.For this reason in existing unit, the rotation deaerator has been installed in fluid intake lower end at centrifugal pump, but this device generally can only be isolated 25% gas flow of total amount of liquid in actual applications, and according to this thinking for separating effect further is provided, rotary separator is changed into multistage rotary separator, this still can not separate oil gas well to the oil field of high gassiness, makes the electric pump cisco unity malfunction.
The purpose of this utility model is exactly to provide a kind of submersible electric pump gas anchor device at the deficiency of prior art, and it can provide the Oil-gas Separation ratio of oil well well liquid, can satisfy the requirement of the normal exploitation of high gassiness oil well electric pump effectively.
The purpose of this utility model is achieved in that a kind of submersible electric pump gas anchor device, and it is made of the cylindrical shell that is installed on the electric pump unit, is provided with seal ring in the annular space that forms between the bottom of cylindrical shell and the protector, and cylindrical shell is higher than the fluid intake of separator.
Described cylindrical shell can be sleeve pipe.
Described cylindrical shell bottom is provided with fixing device.
Described fixing device can be one and hangs tag, and it can be located at the bottom of separator liquid suction port.
The top of described cylindrical shell can be provided with fixed block.
The utility model is simple and reasonable, installation, easy to use, and manufacture cost is lower, can be applied in effectively in the unit of high gassiness well recovery, has improved the ratio of Oil-gas Separation.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that is installed on the electric pump unit of the present utility model;
Fig. 3 is the structural representation of the utility model seal ring;
Fig. 4 is the structural representation that hangs tag of the present utility model.
Referring to Fig. 1,2,3,4; a kind of submersible electric pump gas anchor device of the utility model, it is made of the cylindrical shell 3 that is installed on the electric pump unit, forms annular space between the bottom of cylindrical shell 3 and the protector 4; it is by seal ring 1 sealing, and cylindrical shell 3 is higher than the fluid intake 13 of separator 8.An annular space 14 is formed at the top at suction port 13.In this annular space, according to the precipitation principle, make Oil-gas Separation: heavy liquid sinks, enter separator to separator suction port 13, the gas that proportion is little moves upward, from cylindrical shell 3 upper end emptying, reach the effect that high gassiness oil well oil vapour separates, guaranteed that electric pump can run well.Its middle cylinder body 3 can a sleeve pipe, can easily cylindrical shell be installed on the unit like this.For fixed cylinder 3, be provided with fixing device at cylindrical shell 3 middle parts, this fixing device can be one and hangs tag 7, and cylindrical shell 3 can screw togather by screw 6 with it and join, and it can be located at the bottom of separator 8 fluid intakes 13.Be similarly further fixed cylinder 3, then can be provided with fixed block 11 at an upper portion thereof.Fixed block 11 supports and sets upright cylindrical shell 3 by on screw 10 fixed cylinders 3.Seal ring 1 is connected with the outer wall of cylindrical shell 3, electric pump protector 4 by screw 2.Seal ring 1 is provided with cable outlet groove 5, and the used cable of unit power passes outlet slot 5 from top to bottom and is connected on the motor.
