Description
Technical field
The utility model relates to a kind of oil field well and recovers the oil with the latent oily permagnetic synchronous motor of low-speed big, belongs to magneto technical research field.
Background technology
Submersible screw pump is the Rodless oil extraction equipment of the large discharge capacity lifting in a kind of down-hole oil, is a kind of important mechanical oil recovery equip ment of oil field new development in recent years.Submersible electric machine with oil is the engine of oil-submersible screw-pump oil production system, and initial general submersible screw pump motor that use and present is threephase asynchronous, and its efficiency and power factor are all lower, and power consumption is larger, causes oil field electricity charge spending huge.Simultaneously, this motor is generally the two poles of the earth simple structure, and rotating speed is higher; And the advantage of submersible screw pump is to process high viscosity and the high crude oil that contains sand, increase along with viscosity of crude, submersible screw pump must could be worked effectively under the slow-speed of revolution, its best rotary speed, generally at 100-5O0r/min, therefore, uses phase asynchronous submersible electric machine with oil need add the rotating speed of decelerator ability output screw pump work needs, the unfavorable aspect of bringing thus is that system effectiveness reduces, volume increases, and it is large that vibration and noise become, and maintenance cycle shortens.
In order to improve system effectiveness, reduce energy consumption, begin one's study both at home and abroad and dive oily magneto to replace threephase asynchronous.What succeed in developing at first is high-speed permanent magnet motor, can improve 2-8 percentage point with same specification three-phase induction motor phase specific efficiency, and all can keep higher efficiency and power factor in 25%-120% nominal load scope, while making light running, energy-saving effect is more remarkable.Weak point is that rotating speed is higher, still needs by decelerator rear drive screw pump.
The problem of bringing to the electric oil submerged screw pump oil extraction system in order to solve decelerator, started to develop low speed high power oil-submersible permagnetic synchronous motor both at home and abroad in recent years with direct drive screw pump.The advantage that adopts this kind motor is to save gear reduction unit, and system becomes simply, and efficiency improves, and maintenance cycle lengthens; But the performance requirement to motor is higher.Russia has realized small-scale application to this in 2008; Domesticly be at present external Experiment in Introduction stage or autonomous Design primary stage, do not have performance parameter to reach optimum product.
