Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used to limit scope of the present utility model.
As shown in Figure 1, the utility model provides a kind of energy storage type electric workover rig electric control system, comprising: Power Management Unit, energy-storage units, vector frequency converter, variable-frequency motor, PLC control system, refer to weight sensor, crown block anti-collision instrument and air compressor.
Energy storage type electric workover rig operationally provides power supply by well site transformer, is judged in operation process by power management module to electric power thus supplied.When well site transformer capacity is sufficient, when can meet workover treatment, power management module can select well site power supply to power separately; When well site, transformer capacity is little, when being in electricity shortage, be equipped with the energy storage type electric workover rig of power-supply management system and energy-storage units, power management module can by making up the deficiency that well site powers to the control of energy-storage units and power supply, in operation process, a general time of lower tubular column and the ratio of non-cutting time are approximately 1:2.5 ~ 3, so just for charging accumulator leaves the sufficient time, well site power supply and energy-storage units combination process, the electric energy needed for workover rig can be met completely, so just substantially reduce the activity duration.
Power supply after administration module controls enters vector frequency converter to drive variable-frequency motor, thus reaches head roll, is connected, subsurface tool is carried out to the effect of landing operation by steel cable on cylinder by derrick top sheave group with hook block.
Whole process carries out control and protection action by PLC control system, by derrick referring to weight sensor sensing lead weight, after PLC control system computing, control signal is passed to vector frequency converter, and vector converter adopts Torque Control mode to drive variable-frequency motor.Simultaneously in operation process by PLC control system detection system ruuning situation, when there is the faults such as heavy overload, clutch air pressure are not enough, for ensureing workover rig and personal safety, can give hydraulic disc brake signal, permission dish variable-frequency motor while of holding cylinder tightly of stopping quits work; PLC control system Real-Time Monitoring air compressor system air pressure, stable gas pressure is related to joint situation between wheel box and cylinder, if occur abnormal, can start stand-by compressor in time; Upper derrick is provided with crown block anti-collision instrument, can not exceed and allow height when ensure that and hoist operation.
The utility model embodiment adopts pulse accumulator system and power management module, vector frequency converter, variable-frequency motor, PLC control system etc. are as critical piece, eliminate the gear trains such as the diesel engine of former workover rig, fluid torque-converter, transmission shaft, right angle gear box, improve drive system efficiency, and achieve and do not affect the effect of carrying out workover treatment by well site power supply situation.
Specifically describe the embodiment of energy storage type electric workover rig electric control system below:
As shown in Figure 2, this electric control system selects well site power supply (1) and pulse energy-storage system (2) to combine the mode of power supply according to field power supply situation, powered by power-supply management system (3) and drive special variable-frequency motor (5) to frequency converter (4), variable-frequency motor is again by reducer casing (6) gear train head roll (7), cylinder (7) is wound with wire rope (12), wire rope (12) one end is connected with hook block (10) by the pulley blocks (9) of derrick crown, utilizes hook block to carry out landing operation to drilling rod or oil pipe (11).Whole operation process implements Torque Control by electric control system to variable-frequency motor (5).
Whole process carries out control and protection action by PLC control system, by derrick referring to weight sensor sensing lead weight, after PLC computing, control signal is passed to vector frequency converter, and vector converter adopts Torque Control mode to drive variable-frequency motor.Simultaneously in operation process by PLC detection system ruuning situation, when there is the faults such as heavy overload, clutch air pressure are not enough, being ensure workover rig and personal safety, can giving hydraulic disc brake signal, permission dish variable-frequency motor while of holding cylinder tightly of stopping quits work; PLC control system Real-Time Monitoring air compressor system air pressure, stable gas pressure is related to joint situation between wheel box and cylinder, if occur abnormal, can start stand-by compressor in time; Upper derrick is provided with crown block anti-collision instrument, can not exceed and allow height when ensure that and hoist operation.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
