Description
Technical field
This utility model belongs to oil field pumping well oil recovery technique field, is specifically related to the stent-type twin-well extracting device of oil that a kind of switched reluctance machines drags.
Background technology
Beam pumping unit, with advantages such as its simple in construction, strong adaptability, convenient operating maintenance, the most should have more than 100 year, and be still current topmost oil production method, and the most each oil field should have more than 90%.Beam pumping unit is mainly made up of parts such as caput Equi Asini, walking beam, connecting rod, crank, reduction box and motor.During oil pumper work, after motor is slowed down by belt reduction box, toggle reduction gearbox output shaft rotary motion is converted to the reciprocating motion of caput Equi Asini, thus drives oil well pump to pump, complete oil recovery process.
Beam pumping unit has played very important effect in China's oil development history.But being as development and the progress of oil recovery technique of science and technology, the drawback of beam pumping unit significantly gets up, the subject matter existed have following some:
1, transmission efficiency is low
Beam pumping unit transmission link is many, the link such as including belt, reduction box, connecting rod, crank, walking beam, caput Equi Asini, down-hole roofbolt, its own mechanical transmission energy loss about 28%.Conventional type beam pumping unit computer collecting system efficiency the most typically only has 12%-23%, the highest only about 30%.
2, the problem that inertial load is excessive
The quadric chain of beam pumping unit makes the characteristics of motion of caput Equi Asini be similar to simple harmonic motion, the biggest at upper lower dead point position acceleration, cause inertial load big, oil pumper is made to bear load excessive, reduction box torque ripple is big, increase gear impact, shorten the service life of reduction box and oil pumper.
3, motor bad adaptability
1) the main supporting threephase asynchronous machine of beam pumping unit, the startup of oil pumper is full-voltage starting, and during startup, electric current reaches 5-7 times of its rated current, impacts big to electrical network and current of electric, and voltage ripple of power network is big.
2) oil pumper is due to self structure and pumping working conditions change, can produce imbalance along with the change of load, and difference is relatively big in up-down stroke runs, the existence so that motor is in operation " generating " phenomenon." generating " had both caused certain energy loss, and electrical network causes again certain disturbance, and burn-down of electric motor accident is more, and maintenance cost is high.The most also make electrical network and motor power factor reduce further, thus cause energy waste.
3) presenting " hardware features " during motor power frequency operation, when load change conversion, impact loss is greatly, meanwhile, masks unbalanced state, causes oil pumper energy dissipation in " weight lifting ".
4) power factor is low, and circuit and reactive loss are big.Generally there is " low load with strong power " phenomenon, time properly functioning, load lightens, and required moment is less, occurs in that the load characteristic of sucker rod and the unmatched problem of mechanical property of motor 23, and power utilization is the lowest.
4, adjust ginseng workload big
Production well proration changes, and when needing to adjust jig frequency, needs to change belt pulley or reduction box, and process is loaded down with trivial details, and dangerous high, workload is bigger.
5, other problem
Conventional pumping unit is mounted on reduction box, but reduction box is as reducing gear, often occurs the gear mechanism abrasion that oil leakage phenomenon and casting flaw cause in running, have impact on oil well and normally produces and oil pumper service life.Secondly, belt, as the drive mechanism between motor and reduction box, also has a lot of shortcomings, when increasing such as electronic opportunity sleety weather or load, belt easily skids, throws switch and break and the phenomenon such as takes off, and causes labor strength to increase, running cost is high, reduces production time efficiency.
