Abstract
The utility model relates to an oil production tool, and particularly relates to a novel screw pump oil production string apparatus. The apparatus includes a motor, a reduction box, a support, a four-way, a sleeve, an oil pipe, a sucker rod, a stator, a rotor, a screen casing, a packer, and a polished rod sealer. the motor is connected to the reduction box and is fixed on the support, the inside of the support is connected to the polished rod sealer, the polished rod sealer is connected to the sleeve via the four-way, the inside of the sleeve is successively provided with the oil pipe and the sucker rod from the outside to the inside, the rotator and the stator are arranged on the sucker rod, the lower part of the stator is provided with the screening casing, and the packer is arranged between the oil pipe and the sleeve. The apparatus is advantageous in being simple in structure and less in occupied area, facilitating the oil production of an offshore platform and a cluster well group, being applicable to a heavy oil well and a sand producer, alleviating the problems of the wearing of screw pump rods and pipes and the coming off of the sucker rod, reducing the happening of downhole accidents, and improving the production efficiency.
Description
Technical field
The utility model relates to a kind of oil tool, particularly a kind of new screw pump flow string device.
Background technology
The screw pump oil production technical applications is relatively broad, not only sticking at height, gassiness, contains on the oil well of sand and is applied, and also obtained application on, the offshore field moisture at height.When performance screw pump solution high viscosity, high gassiness, height contain the difficult superiority of sand oil well well liquid pumping, cooperate various sand control measures and electrical heating hollow rod, the application of screw pump is constantly widened.Have screw rod pump rod, pipe wearing and tearing and rod parting problem at present in process of production, down-hole accident is multiple, influences ordinary production.
The utility model content
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of new screw pump flow string device is provided, and is simple in structure, the little production efficiency that improved of floor space.
Its technical scheme is: mainly be made up of motor, reduction box, support, four-way, sleeve pipe, oil pipe, sucker rod, stator, rotor, screen casing, packer, polished rod sealer; Motor is connected with reduction box and is fixed on the support; Internal stent is polished rod sealer fixedly; Polished rod sealer is through the four-way splicing sleeve, and the inside ecto-entad of sleeve pipe sets gradually oil pipe and sucker rod, and described sucker rod is provided with rotor and stator; The stator bottom is provided with screen casing, is provided with packer between oil pipe and the sleeve pipe.
The beneficial effect of the utility model is: simple in structure, floor space is little, helps offshore platform and cluster well group and recovers the oil; Being fit to heavy oil wells and sand output well uses; Alleviate screw rod pump rod, pipe wearing and tearing and rod parting problem, reduced the generation of down-hole accident, improved production efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: motor 1, reduction box 2, support 3, four-way 4, sleeve pipe 5, oil pipe 6, sucker rod 7, stator 8, rotor 9, screen casing 10, packer 11, polished rod sealer 12.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of motor 1, reduction box 2, support 3, four-way 4, sleeve pipe 5, oil pipe 6, sucker rod 7, stator 8, rotor 9, screen casing 10, packer 11, polished rod sealer 12; Motor 1 is connected with reduction box 2 and is fixed on the support 3; Support 3 internal fixation polished rod sealers 12; Polished rod sealer 12 is through four-way 4 splicing sleeves 5, and the inside ecto-entad of sleeve pipe 5 sets gradually oil pipe 6 and sucker rod 7, and described sucker rod 7 is provided with rotor 9 and stator 8; Stator 8 bottoms are provided with screen casing 10, are provided with packer 11 between oil pipe 6 and the sleeve pipe 5.
Screw pump is to lean on the cavity oil extraction, and when rotor rotation, enclosed cavity is migrated to the outlet side direction by sucking end along axis direction.Enclosed cavity disappears at outlet side, and the crude oil in the cavity also just is extruded into outlet side by sucking end thereupon equably.Simultaneously, forming new low pressure cavity again at the suction end again sucks crude oil.Like this, enclosed cavity constantly forms, migrates and disappears, and crude oil just constantly is full of, pushes and discharges, thereby constantly sucks the crude oil in the well, gives rise to well head through oil pipe.
The screw pump oil production technical applications is relatively broad, not only sticking at height, gassiness, contains on the oil well of sand and is applied, and also obtained application on, the offshore field moisture at height.When performance screw pump solution high viscosity, high gassiness, height contain the difficult superiority of sand oil well well liquid pumping, cooperate various sand control measures and electrical heating hollow rod, the application of screw pump is constantly widened.
