Abstract
The utility model discloses a hydraulic screw pump, which includes an upper bi-pass, an upper motor, a mixed flow external tube, a middle universal shaft, a bypass valve, a lower screw pump, a lower universal shaft, a bearing case and a protector. The top of a bypass valve is connected with the mixed flow external tube, the bearing case and protector in turn. The top of the middle universal shaft is connected with the top of the motor rotator; the lower end is connected with the rotor of the lower screw pump. The upper end of the lower universal shaft is connected with the rotator of the lower screw pump; the lower end is connected with the bearing case and the protector The utility model is provided with an oilfield water injection system as a power of the water source to drive top motor rotator to rotate and drive the lower screw oil extraction pump and the universal shaft structure so as to overcome or prevent shoulder wear of oil well pipe; which greatly saves energy consumption; the device especially suitable for thick oil, sand flow and some of gas contained wells and is widely used in the oil extraction technology of petroleum exploration.
Description
One, technical field
The utility model relates to screw pump, particularly a kind of waterpower screw pump.
Two, background technique
Existing petroleum production screw pump (ground driving screw pump or electric oil submerged screw pump), be by electrical actuation power, has the outstanding feature that adapts to viscosity, the higher oil well of sand content, but because the ground driving screw pump structural reason exists rod and tube partial-wear, cause damage, dropout, disconnected bar, the life-span is short and can only use in the straight well section, shortcoming or deficiency such as can not be adapted to use in inclined shaft, horizontal well and the thick oil well, then there is big energy-consuming in electric oil submerged screw pump, shortcoming or deficiency that the life-span is short.
Three, summary of the invention
The purpose of this utility model provides a kind of improved waterpower screw pump, utilize the reciprocal principle of screw rod mechanism, adopt the water of the oil field flood pattern source that is used as power, the drive screw motor changes rotation, the drive progressive cavity pump recovers the oil, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Waterpower screw pump described in the utility model; comprise top bilateral, top motor, mixed flow outer tube, middle part cardan shaft, bypass valve, bottom screw pump, bottom cardan shaft, screen casing, bearing housing and protector; described bypass valve top is connected with mixed flow outer tube, bearing housing and protector in turn; cardan shaft upper end, described middle part is connected with the top motor rotor; the lower end is connected on the screw pump rotor of bottom; cardan shaft upper end, described bottom links to each other with the bottom screw pump rotor, and the lower end links to each other with bearing housing and protector.
Wherein, constitute the annular space runner between described mixed flow outer tube and the top motor case.Motor bottom, described top is provided with flowing hole, and it is connected with described annular space runner.Described bypass valve is provided with the duct that the outside is connected.
The utility model has following advantage compared with prior art:
1, adopts oil-field flooding net water to be used as power, need not establish special hydrodynamic system in addition, save electric energy in short supply.
2, adopt profit to mix out, up with oil-in-water form from interior pipe and oil pipe annular space, realize the core heating, thermal efficiency height reduces the up frictional resistance of oil-water media, and oil-water ratio can reach more than 1: 6.
3, because profit mixes out, structural factors such as heating and cardan shaft, avoid side-abrasion of rod string, protection oil well pipe bar is injury-free, increases the service life.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the utility model.
Five, embodiment
Consult accompanying drawing; a kind of waterpower screw pump; comprise top bilateral 1, top motor 2, mixed flow outer tube 3, middle part cardan shaft 4, bypass valve 5, bottom screw pump 6, bottom cardan shaft 7, screen casing 8, bearing housing 9 and protector 10; bypass valve 5 tops are connected with mixed flow outer tube 3, bearing housing 9 and protector 10 in turn; cardan shaft 4 upper ends, middle part are connected with top motor 2 rotors; the lower end is connected on bottom screw pump 6 rotors; cardan shaft 7 upper ends in bottom link to each other with the bottom screw pump rotor, and the lower end links to each other with bearing housing 9 and protector 10.
Constitute the annular space runner between mixed flow outer tube 3 and top motor 2 shells.Motor bottom, top is provided with flowing hole, and it is connected with described annular space runner.Bypass valve 5 is provided with the duct that the outside is connected.
