Description
Technical field
The utility model is related to the technical field of energy storage of drilling engineering, specifically a kind of workover rig storage based on super capacitor
Can system.
Background technology
In petroleum drilling engineering field, workover rig operating type can be summarized as three major types：
（1）Rountrip：Such as oil pipe, sucker rod, deep well pump downhole operation equipment and instrument are removed, and pumping,
Drag for sand, mechanical paraffin removal rise it is inferior；
（2）Rotary operation：Such as drilling out, sand plug is bored, and reaming, be redrilled, deepen and casing repairing etc.；
（3）Liquid circulation operation：Such as sand washing, hot wash, squeeze method and circulating mud rotary operation.

Regenerate.The vehicle mounted electric workover rig of novel variable-frequency speed regulation will certainly replace the workover rig that conventional diesel is dynamic work.And well site
In remote districts more than power network, typically it is only capable of providing the power supply that three-phase 1140V, power are about 50kW.And winch motor power
For three-phase 400V, 110kW, grid power is not enough when causing the workover rig to work, and speed does not reach rated value, influences drilling efficiency.
During by tens tons of drilling tool repeatedly tens meters of depths of put-on and delegated, energy expenditure is huge, especially in trip
The energy that skidding is consumed in crane system decentralization process is lost with form of thermal energy, is caused great energy waste, is added
Diesel generating set has considerably long one end time to be in Light Condition, has a strong impact on the fuel economy of diesel engine and uses the longevity
Life.
