Side, it is connected by pipeline with natural gas power unit, fuel is provided for it；After driller's control room is installed in trailer chassis left side
Portion, derrick assembly are arranged on trailer chassis afterbody, electric power management device input by cable respectively with generator, flywheel energy storage
Device connects, and the motor on output end connection multi-gear gear-case, driller's control is installed on by the control unit of control cable connection
In room.
Multi gear gear shift winch, which is bolted, is installed on trailer chassis postmedian, is become by motor, shaft coupling, more gears
Fast case, master rotor and auxiliary brake composition, motor output shaft input axis connection, multi-gear transmission by shaft coupling and multi-gear gear-case
Case output shaft is integrated altogether with master rotor central shaft, and the master rotor central shaft other end is connected with auxiliary brake.
One end of steel wire rope is connected with master rotor, and the other end is connected after overhead traveling crane on derrick assembly with hook block, trip
Car hook is connected with tubing string.
The beneficial effects of the utility model：
1. workover rig uses integrated trailer transportation, dismounting, installation and movement efficiency high, when reducing operation preparation
Between, realize that more workover rigs share a tractor, reduce drilling team's special vehicle human pilot.
2. the application of natural gas power unit can reduce fuel cost about 20%, while the row of pollution synthesis is greatly decreased
Put, realize PM2.5 zero-emissions.
3. workover rig configures energy accumulation device for fly wheel, the electric energy that gap generator is sent between storage operation, in high-power riser
Discharged during post, make up power swing, engine can be made to operate at greater efficiency all the time.
4. tubing string can be transferred to the part potential energy discharged to be converted into electric energy and be used, greatly reduce and repair
Well operations cost.
