Description
Affiliated technical field
The utility model belongs to the petroleum machinery technical field.
Background technology
Recover the oil and use rod beam-pumping units more in the oil field at present, uses the rod beam-pumping unit oil pumping, the equipment cost height, and power consumption is big, and the employing screw pump that has now had is pumped to the down-hole down, replaces existing rod beam-pumping unit.Though use screw pump extraction oil that application is arranged, the drive screw pump all uses motor, connects motor one and removes the down-hole, motor is fragile under the situation that screw pump blocks.The more important thing is that screw pump oil production only is applicable to low viscous crude oil, and is inapplicable for thickened oil recovery.
Summary of the invention
Use the problem that screw pump is adopted viscous crude in order to solve, the utility model provides a kind of heavy crude heat extraction all-hydraulic all-in-one.
The utility model is made up of heater, hydraulic pump, overflow valve, pressure meter, reversal valve, hydraulic motor, screw pump, radiator, one way valve, fluid pressure line, shaft coupling etc.Hydraulic power unit is more than ground, the heat conduction fuel tank is connected with the oil rig of down-hole by fluid pressure line, hydraulic pump, pressure meter and reversal valve are housed on pipeline, the heat conduction fuel tank is equipped with heater, on heat conduction fuel tank and the branch road that fluid pressure line is connected overflow valve is housed, fluid pressure line stretches in the well casing, in the below ground well casing, screw pump is housed, the top of screw pump links to each other with the hydraulic motor turning cylinder by shaft coupling, hydraulic motor links to each other with fluid pressure line, and fluid pressure line is equipped with radiator and one way valve on hydraulic motor top.It is in parallel that radiator and hydraulic motor belong to, and one way valve is connected on the radiator.The type of the hydraulic motor that the utility model is used can be various forms such as plunger type, cycloid tooth be wheeled.The axle of this hydraulic motor is not an entity, but the logical axle of a hollow, and the two ends shaft, on the sidewall of hollow shaft, have fuel feed hole, oil can enter in the hollow shaft tube chamber by the hole on this hydraulic motor hollow shaft sidewall, and the one way valve that backs down a top enters well casing and rises on the ground.Connect the shaft coupling particular design of hydraulic motor and screw pump, on the external surface of shaft coupling, paddle is housed.
More than ground, hydraulic oil adopts conduction oil and is heated to more than 100 ℃ by heater.Before oil pumping, earlier deep fat is sent into undergroundly by hydraulic pump, opened one way valve and flow through that heating descends viscosity of crude to radiator to viscous crude.By the reversal valve commutation, the hydraulic motor rotation drives the screw pump oil pumping then.Hydraulic motor and screw pump connect by shaft coupling, and the turning cylinder of hydraulic motor is provided with an one way valve in the top for logical core structure, and the crude oil that draws up can not be returned.When screw pump rotates with hydraulic motor crude oil is drawn up after oil-out enters pump and motor connection chamber, fluid enters logical axle by the side opening on the motor drive shaft, backs down one way valve and enters well casing at last, rises to more than the ground.
In order to prevent sand grains precipitation in the crude oil, shaft coupling is designed to have the paddle structure, so that do not stop to stir crude oil.
The turnover oil pipe of hydraulic motor all within the crude oil well casing until ground, and the hydraulic oil in the oil pipe is deep fat, the crude oil that draws up is heated in well casing all the time and is unlikely to cooling viscosity is increased.
The journey loss of prolonging of hydraulic flow all becomes heat with the merit that local resistance loss is consumed in the fluid pressure line, and this heat is just beneficial to reducing crude oil viscosity, can make the power of hotline heater save a part of.
The utility model has solved the problem that screw pump is adopted viscous crude of using.It is all-hydraulic integrated that heavy crude heat extraction is realized, equipment cost is low, reduces power consumption.
