Control water injection rate manually because existing oil field flood pattern adopts usually, therefore causing water-injection efficiency low and there is very large maloperation may.Meanwhile, Non-follow control water injection rate often can not regulate water injection rate timely and effectively.For solving the problem, the utility model discloses a kind of new oil field flood pattern.
Structured flowchart below in conjunction with Fig. 1-3 describes the utility model one embodiment in detail.As shown in Figure 1, in the present embodiment, flood pattern comprises charging state acquisition device 101, main road device 130, converter plant 110 and mair motor 140.
As shown in Figure 2, it comprises charging state analysis module 231 and the first variable frequency control module 232 to the Inner Constitution block diagram of main road device 130.Charging state analysis module 231 is connected with charging state acquisition device 101 and the first variable frequency control module 232.Charging state acquisition device 101 is for obtaining the current water filling situation of flood pattern and outputting to charging state analysis module 231.Charging state analysis module 231 is analyzed current water filling situation and is then exported analysis result to the first variable frequency control module 232.First variable frequency control module 232 is connected with converter plant 110, and it exports output first frequency change control signal according to analysis result thus controls the output of converter plant 110.
As shown in Figure 1, converter plant 110 is connected with AC network 100 and is connected to mair motor 140.The alternating current of AC network 100 is converted to the first alternating current based on the first frequency change control signal and outputs to mair motor 140 by it.Mair motor 140 drives water pump 103 to carry out water filling based on the first alternating current.
The parameters such as the current charging state information that charging state analysis module 231 exports based on charging state acquisition device 101 and plan water injection rate change the first frequency change control signal automatically, thus control the output of converter plant 110, and then control the power output of mair motor 140, finally reach the object of control system water injection rate.That is, when the hydraulic pressure of the current output of system cannot meet plan water injection rate, state analyzer 132 can automatically control mair motor 140 and improve power output.Otherwise when the hydraulic pressure of the current output of system makes water injection rate exceed plan water injection rate, state analyzer 132 can automatically control mair motor 140 and reduce power output.
Compared to controlling manually, the utility model utilizes main road device automatically to control water injection rate based on based on actual charging state and plan water injection rate, which not only reduces the labour intensity of field worker, decrease misuse rate, and substantially reduce the response time of runoff investigation, improve the actual effect of water rate control.Adopt the utility model, the control accuracy of runoff investigation also improves greatly simultaneously.
Due in actual motion, the water injection rate of flood pattern often changes, and therefore the power output of mair motor 140 is often in variable condition.And under mair motor 140 operates in non-rated power state usually.In above-mentioned running environment, the operational efficiency of common asynchronous machine and power factor are all very low, and this just causes very large energy waste.
In the present embodiment, employing utilizes permanent-magnet material to make the magneto of rotor as mair motor 140.Compared to common asynchronous moter, magneto simplifies the structure of motor, improves the magnetic energy reserves of motor.Compared with the common asynchronous moter of same power, magneto volume is little, lightweight, operation is more reliable.Due to the characteristic properties of rare earth permanent-magnetic material, magneto all can keep higher efficiency and power factor in the rated operating range of 25% ~ 120%, thus energy-saving effect is more obvious when light running, preferablyly to operate in the running environment that power output often changes.Simultaneously, its rated efficiency comparatively common asynchronous moter improves 3% ~ 5% to this motor, and average power saving rate is more than 10%.Magneto adopts F class B insulation, can run without interruption for a long time, avoids the motor frequent shutdown caused due to temperature rise and falls the trouble of pump.
When actual water filling, often run into the situation that still cannot meet plan water injection rate after motor reaches maximum power output.Now usually adopt the mode increasing flood pattern to improve overall water injection rate.But this considerably increases cost, and multisystem Collaborative Control also makes the control of water injection rate more complicated, thus have impact on promptness and the precision of water injection rate control.For solving the problem, the utility model utilizes the mode increasing stand-by motor to increase water injection rate.
As shown in Figure 1, flood pattern also comprises shunting device 120 and the first stand-by motor 141.Again as shown in Figure 2, main road device 130 also comprises the first switch control module 234 and motor status analysis module 233.First switch control module 234 is connected with motor status analysis module 233, first switch 151, shunting device 120, first variable frequency control module 232 and charging state analysis module 231.Motor status analysis module 233 is for obtaining and output motor state analysis result.When the first switch control module 234 to judge under current mair motor 140 has been operated in peak power and still cannot meet plan water injection rate, it exports bypass start-up order thus opens shunting device 120 and carries out auxiliary water filling.
As shown in Figure 1, flood pattern also comprises the 3rd switch 153, and it is connected with shunting device 120 and is connected between AC network 100 and the first stand-by motor 141.3rd switch 153 is for controlling the break-make between AC network 100 and the first stand-by motor 141, and it is configured to the on off operating mode switching self based on the 3rd switch on and off order from shunting device 120.Shunting device 120 opens switch 153 based on the bypass start-up order received, thus the first stand-by motor 141 is operated.
In the present embodiment, the rated power of the first stand-by motor 141 and the peak power output of mair motor 140 are consistent, and when the direct incoming transport electrical network of the first stand-by motor 141, its work under nominal power.Therefore when the 3rd switch 153 is opened, the first stand-by motor 141 drives water pump 103 water filling, and its water injection rate produced is equivalent to water injection rate when mair motor 140 is in peak power.The basis that first stand-by motor 141 runs controls mair motor 140 and carries out water filling, thus solve the situation of water injection rate deficiency.
Due to the first stand-by motor 141 once work, its work under nominal power and usually do not need the first stand-by motor 141 long-play.Therefore do not need to consider the power saving of the first stand-by motor 141 under other operating modes as consideration mair motor 140.In the present embodiment, for cost-saving first stand-by motor 141 adopts common asynchronous machine.
Due to flood pattern incoming transport electrical network 100, therefore once the change of voltage in AC network, the motor in flood pattern and miscellaneous part directly can be had influence on.In order to protect flood pattern, improve security of system degree.First as shown in Figure 1, the output of AC network is connected with line breaker 190.The alternating current that line breaker 190 inputs for controlling AC network, so that the connection cutting off between whole flood pattern and AC network 100 when sharp voltage change occurs AC network 100.Secondly, the utility model also comprises the first protection circuit 161.Motor protective circuit 161 is connected on the input of the first stand-by motor 141, for reducing the impact of electric current input to motor, thus protection the first stand-by motor 141.
Although adopt stand-by motor to increase water injection rate, when the first stand-by motor 141 works, its moment directly accesses electrical network, and the electrical network switching shock now produced can affect the life-span of the first stand-by motor 141 greatly, thus reduces the reliability of flood pattern.For addressing this problem, flood pattern of the present utility model additionally uses the method starting the first stand-by motor 141 gradually.As shown in Figure 1, flood pattern also comprises second switch 152, and as shown in Figure 3, shunting device 120 comprises the second variable frequency control module 321 and second switch control module 322.Second switch control module 322 is connected on the first switch control module 234 of main road device 130, second switch 152 and the 3rd switch 153.On the first switch control module 234 that second variable frequency control module 321 is connected to main road device 130 and converter plant 110.
As shown in Figure 1, flood pattern also comprises the first switch 151, and as shown in Figure 2, the first switch control module 234 is connected with the first switch 151.When needs startup shunting device 120 carries out auxiliary water filling, first the first switch control module 234 controls the first variable frequency control module from service.Then export the first switch on and off order turn off the first switch 151 and export bypass start-up order to shunting device 120 simultaneously.
As shown in Figure 1, the first switch 151 is connected between converter plant 110 and mair motor 140, for controlling the break-make between converter plant 110 and mair motor 140.First switch 151 is configured to the on off operating mode switching self based on the first switch on and off order.After the first switch control module 234 exports the first switch on and off order, the first switch 151 cuts off the connection between converter plant 110 and mair motor 140, and mair motor 140 is quit work.
As shown in Figure 1, second switch 152 is connected between converter plant 110 and the first stand-by motor 141, for controlling the break-make between converter plant 110 and the first stand-by motor 141.Second switch 152 is configured to the on off operating mode switching self based on the second switch break-make order from second switch control module 322.When not needing auxiliary water filling, shunting device 120 is in holding state, and now second switch 152 and the 3rd switch 153 are dissengaged positions.
After second switch control module 322 receives bypass start-up order, first it export the order of second switch break-make thus open second switch 152.Meanwhile, the second variable frequency control module 321 receiving bypass start-up order exports the second frequency change control signal and controls converter plant 110.The alternating current of AC network 100 is converted to the second alternating current based on the second frequency change control signal and exports by converter plant 110.First stand-by motor 141 slowly starts under the driving of the second alternating current.Under the control of the second frequency change control signal, the frequency of the second alternating current raises gradually, thus makes the first stand-by motor 141 improve power output gradually and finally reach rated power.
When the output of the first stand-by motor 141 reaches rated power, the second alternating current of its two ends input is just equivalent to the alternating current in AC network 100 substantially.Now second switch control module 322 exports the order of second switch break-make and the 3rd switch on and off order, thus turns off second switch 152 and open the 3rd switch 153, and the direct incoming transport electrical network 100 of the first stand-by motor 141 is worked.
Although said method makes the first stand-by motor 141 avoid from the direct incoming transport electrical network 100 of shutdown, thus reduces starting current impact.But be switched in this process of AC network 100 from converter plant 110, still having rush of current to produce.For reducing rush of current to greatest extent, in the present embodiment, as shown in Figure 3, shunting device 120 also comprises phase locking unit 323.Phase locking unit 323 is connected with AC network 100, converter plant 110 and the second variable frequency control module 321.Exporting the second frequency variation signal in the second variable frequency control module starts in the process of the first stand-by motor 141 gradually, and phase locking unit 323 utilizes principle of phase lock loop to control the output of the second variable frequency control module 321.The second alternating current that final converter plant 110 is exported consistent with the alternating current in AC network 100 (voltage magnitude, phase place are consistent).And first open the 3rd switch 153 at the final converter plant 110 that switches with during AC network 100, make AC network 100 and converter plant 110 drive the first stand-by motor 141 simultaneously, then turn off second switch 152.In whole process, the first stand-by motor 141 has power drives all the time, there is not power down process, and whole handoff procedure no current impacts, and can not impact the first stand-by motor 141, thus realizes switching without impacting of AC network 100 and converter plant 110.
For reducing the rush of current that the first stand-by motor 141 is subject to further, in the present embodiment, as shown in Figure 1, flood pattern also comprises loop current suppression device 180.Loop current suppression device 180 is connected on the output of converter plant 110.The circulation that the voltage change ratio of the alternating current that loop current suppression device 180 exports for reducing converter plant 110 and suppression converter plant 110 outlet side are formed, thus reduce or eliminate the infringement to common asynchronous moter insulation.
When actual motion, because mair motor 140 is in long time running, compared to the first stand-by motor 141, there is larger fault rate in it.In order to increase the reliability of whole system, in the present embodiment, as shown in Figure 1, flood pattern also comprises fault monitor 170.Fault monitor 170 is connected with mair motor 140 and main road device 130, for monitor the running status of mair motor 140 and output motor monitoring result to main road device 130.When mair motor 140 fault, fault monitor 170 sends fault cues, and main road device 130 cuts off the first switch 151 based on the fault cues received and sends instructions to shunting device 120.Shunting device 120 opens second switch 152, connects converter plant 110 and the first stand-by motor 141.Be understood that, now the first stand-by motor 141 can the work of adapter mair motor 140.Main road device 130 can export based on actual water filling situation the output that the first frequency change control signal controls converter plant 110, thus control the first stand-by motor 141 carries out water filling.
Based on above-mentioned pattern, make still can ensure the normal water filling of whole flood pattern before staff keeps in repair mair motor 140 or in maintenance process, avoid the impact of system-down on overall injection project, substantially increase the reliability of system.
In actual motion, though also also exist start the first stand-by motor 141 and mair motor 140 is also in maximum power output time water injection rate still cannot reach the situation of plan water injection rate.Similarly increase the first stand-by motor 141, the present embodiment adds the second stand-by motor 142.As shown in Figure 1, flood pattern also comprises the second stand-by motor 142, the 4th switch 154, the 5th switch 155 and the second protection circuit 162.
Second protection circuit 162 is connected on the input of the second stand-by motor 142, for reducing the impact of input current to motor.
4th switch 154 is connected to second switch control module 322 and is connected between converter plant 110 and the second stand-by motor 142.5th switch 155 is connected to second switch control module 322 and is connected between AC network 100 and the second stand-by motor 142.The similar second switch 152 of concrete effect of the 4th switch 154 and the 5th switch 155 and the 3rd switch 153, just seldom repeat here.When mair motor 140 is in peak power output and the water injection rate of system does not meet plan water injection rate, if the first stand-by motor starts.Then when maintenance first stand-by motor 141 running status is constant, start the second stand-by motor 142 according to the process of startup first stand-by motor 141.
Although embodiment disclosed in the utility model is as above, the embodiment that described content just adopts for the ease of understanding the utility model, and be not used to limit the utility model.Technician in any the utility model art, under the prerequisite not departing from spirit and scope disclosed in the utility model, can do any amendment and change what implement in form and in details.But scope of patent protection of the present utility model, the scope that still must define with appending claims is as the criterion.
