The motor of speed regulation is bis- pole three 1250kW/660V asynchronous machine, is easy to implement fixed-voltage altering-current amount speed regulating control.
The working principle of the invention: two major class of water injecting pump point at present, one kind are centrifugal multistage pump multiple centrifugal pump, and another kind of is high-pressure plunger
Pump, respectively there is advantage and disadvantage.It is energy-efficient based on plunger pump with the appearance of external import brand plunger pump assembly enlargement product
Advantage replaces centrifugal multistage pump multiple centrifugal pump to have been achieved for extensive market recognition using the big-flow high-pressure plunger pump of import brand.
Centrifugal multistage pump multiple centrifugal pump working principle is to increase liquid energy step by step by impeller, what pump has be increased by several times, work
Pressure is directly proportional to the series of revolving speed, impeller diameter and pump；Flow is directly proportional to revolving speed and impeller width.Such as deviate declared working condition
Operation, then real pump effect rate is far below pump design efficiency.The discharge capacity of centrifugal pump can be needed to export by system pressure influence of fluctuations, discharge capacity
Regulating valve is adjusted, to cause a large amount of waste of energy.
Centrifugal pump fragile part is more, and maintenance cost is higher, heavy workload, and overhaul needs all to disintegrate, replacement impeller, each
Components, the rotors such as grade choma, guide vane, bearing need to verify dynamic balancing again, need professional machine maintenance strength.
Centrifugal pump advantage: running smoothly, and is suitable for big flow, low lift situation.
: easily there is surge in centrifugal pump disadvantage, and single-stage pump, which forces down, the efficiency of pump is low, there is outlet lift gradually declines situation.
Plunger pump is moved by piston reciprocation, and the pressurized delivered to medium is realized in constantly sucking and discharge liquid medium.
Discharge capacity is related with revolving speed and diameter of plunger and stroke, and pressure is related with arranged medium pipeline characteristic, and maximum pressure depends in pump
In the power of motor of quality and outfit.Plunger pump displacement constant under setpoint frequency, not by system pressure influence of fluctuations.Plunger pump
Only need to regularly replace plunger packing under normal operating maintenance, the power end rotatable parts service life of plunger pump was up to 25 years or more.
Plunger pump advantage: compact-sized, pressure is high, pump efficiency is high, few easy workout part, easy to operate and maintain
Plunger pump disadvantage: the discharge of liquid is the reciprocating motion by plunger, will lead to fluid and generates pulse, but adds
Pulsing effect can be completely eliminated after outlet surge tank.
One mine apricot of the 4th oil recovery factory of Daqing oil field, 18 water-injection station water injecting pump equipment operation condition summarizes Daqing oil field the
Four oil recovery factories, one mine apricot, 18 water-injection stations are new, and old two water filling hilllocks were built up in 2006 and 1993 puts into operation, fill the water at present
It stands about 13400 cubes of average daily water injection rate (i.e. 550 cubic meters/hour).Water-injection station shares 6 multistage centrifugal water injecting pumps, wherein 4 notes
Pumps design flow 250m3/h, 1650 meters of lift, model DF250-150x11.
18 water-injection station of Daqing oil field apricot possesses 6 multistage centrifugal water injecting pumps at present, using 2 operations (1)
250m3/h and 1 300m3/h), 4 spare modes carry out flooding production.Since service life is longer, equipment is old, centrifugation
Pump has been unable to reach its design value, and DF250 multistage centrifugal water injecting pump daily total power consumption in 1 now run is about
40680KW, about 26442 yuan of the daily electricity charge, water filling unit consumption is 6.72kw/m3.
The efficiency of centrifugal pump that scene operation at present uses is relatively low, and theoretically centrifugal pump nameplate efficiency is all 73%, at present in fact
Border monitors service efficiency 60% or so, influences pump operation effect.
Mainly there is following factor:
1. the manufacture and Overhaul Quality of pump be not high, decline the way.
2. pump cannot be maintained at from the operation of effect area, water injecting pump external system parameters and pump performance operating parameter are mismatched.With
The sternness of water filling Development Finance, water-injection station water supply capacity increasingly mismatches with outer net demand, and the operational efficiency of pump is caused to drop
It is low.To realize operation optimization ,-aspect needs technical staff's water injection rate in conjunction with needed for pump characteristic curve, water-injection station, pressure to become
Change trend pumps combined running by different model, compares and analyzes to parameters such as pump pressure, pump efficiency, unit consumption, summarizes water injecting pump
Optimum operation mode.
6 water injecting pumps in one mine apricot of the 4th oil recovery factory of Daqing oil field, 18 water-injection station at present, wherein 3 water injecting pumps are
Operation uses 10 years or more, and the problems such as due to On-the-spot factor and maintenance, these pumps have reached the maximum service life, is badly in need of more
It changes.
The water injecting pump service life, the-was service life, and the usual period is longer there are two concept ,-as at 10 years or more.Second
It is normal service life, refers to the service life of vulnerable part and the overhaul time by pump performance indicators trial running during pump operation
Limit.The factor for influencing the water injecting pump service life mainly has water quality, material and process and assemble quality.
6 water injecting pumps at present -18 water-injection station of mine apricot scene there are problems that various using the often parking of needs
Maintenance.
Especially wherein 3 operations use 10 years or more water injecting pumps, and internal impeller and bearing fouling are serious, can not
It is filled the water according to design discharge, urgent need more renews pump, it is ensured that the normal operation of water-injection station.
Our company is investigated by the on-the-spot investigation to water-injection station scene, and the technology for having provided more advantage according to field condition changes
Scheme is made,
Concrete scheme is as follows
1. removing original 1 DF250 water injecting pump.
2. increasing by 1 5SPH880-150/32 water injecting pump in original position.
The upgrading to water injecting pump is completed in the case where changing very little, improves the service life of water filling pumping unit and is expired
Sufficient oil field produces waterflooding requirement.
It is recorded according in 6 centrifugal multistage pump multiple centrifugal pump scene operating parameters of the 18 water-injection station scene of apricot to flood pattern
Analysis, our company think rationally to be transformed.Using 1 5SPH880-150/32 plunger pump (working flow 250m3/h, work
Make pressure 16.5MPa) the 1 DF250 water injecting pump run now is replaced, to meet the daily water injection rate of water-injection station.Remaining state
It is spare to produce DF250 centrifugal tundish, in case parking maintenance works.
The 1 5SPH880-150/32 plunger pump increased newly after removing original 1 domestic multistage centrifugal water injecting pump can be with
It is mounted in original water injecting pump workshop, no longer needs to newly construct the factory buildings to dispose new water injecting pump.
Water flood recovery is the common measure that many oil fields keep stable high yield.Principle is exactly spreading in oil-producing region stratum
Oil focuses near oil well, then extracts up.For fracture block oil field since each block water filling range is relatively small, water injection rate
With the variation of the extension oilbearing stratum situation of mining time, often to adjust.Oil-field flooding is since pressure is high, water is big, water filling
Motor is high power motor mostly, and motor is chronically at the operation of highly energy-consuming state.And actually water flooding pump station is in construction
All there are problems that metered flow is not matched that with actual flow.For above situation, it is believed that use frequency converter
Variable speed is carried out to oil-field flooding pump motor to adjust, and realizes that the control of water injecting pump variable water volume is that a very effective energy conservation is arranged
It applies.
Old filed much all has water flooding pump station when founding the factory, and is supplied water using high pressure water injection mode, the size and pressure of flow
The height of power realizes control using flashboard valve.According to the technological requirements, long-time small displacement is not allowed to run, otherwise water injecting pump meeting
The problems such as cavitation and parts are burnt caused by increasing because of temperature, therefore be forced to reduce temperature rise using big reflow method, it results in this way
A large amount of consumption of electric power cause a large amount of energy loss to oil field, increase the production cost of enterprise.
In former designing system operating condition, system water filling is carried out frequently with two water injecting pumps.The flood pattern energy consumption of the operating condition
Loss is mainly in control valve throttling.By our analysis, as long as reducing water by combining DP technology is needed to match fluence
Pressure, the valve for reducing each hollow well control pressure difference, it should can achieve the purpose that energy-saving.
Variable frequency water supply control principle
Due to the actual flow of water injecting pump be certainly less than or equal to pump metered flow, have certain energy conservation potential.
The water filling control of frequency-conversion water supply system water injecting pump is by frequency converter by the feedback pressure value of pressure transmitter, and is preset in frequency conversion
Pressure value in device is compared, and operation adjusting is carried out according to difference by the PID regulator in frequency converter, to control frequency conversion
Device frequency control operation；Meanwhile the operating parameter of frequency converter can be passed by the communication interface and communications protocol of frequency converter institute band
Transport to computer workstation；System running pressure, motor speed, input/defeated can be detected and controlled at any time on computers
The parameters such as voltage, input/output electric current out achieve the purpose that system automatic energy saving is run.
Water supply pumping plant in Oilfield Operation District often shares three same vertical water injecting pumps of model, and two is standby with one.The specified function of motor
Rate 1250KW, voltage rating 6000V, rated current 1400A or so, 2900 revs/min of rated speed, rated frequency 50HZ, absolutely
F grades of edge grade.The transformation of frequency converter timing constant pressure water supply is carried out for the water injecting pump two spare actual conditions that work.
Control process is: being pumped when water consumption is few by Frequency Converter Control 1, carries out constant pressure water supply control.When water consumption gradually
When increasing the working frequency of No. 1 pump and reaching close to 50HZ, its motor is switched into power frequency supply power supply, while frequency converter being cut
It changes on No. 2 pumps, carries out supplement water supply by No. 2 pumps, conversely, when water consumption gradually decreases, even if the working frequency of No. 2 pumps has dropped
For lower frequency limit.And pressure of supply water it is still bigger than normal when, then turn off No. 1 pump, while increasing the working frequencies of No. 2 pumps rapidly, and carry out
Isobarically Control.This scheme is mainly characterized by only with a frequency converter, and the calculating that this scheme takes electrical power is as follows:
Assuming that the no-load loss of motor are as follows: 10%
The specified water supply flow of pump: Qn
Drive motor capacity: Pm
Daily average total water supply flow are as follows: 160%Qn
The drive motor capacity of 1250KW: Pmn=1250KW,
No. 1 pump is full speed, averagely takes power: Pml=1250KW
The 60% of the mean speed of No. 2 pumps, averagely take power: Pm2=(0.6*1250) KW=750KW two pumps take
Total mean power: 1250+750=2000KW
Power saving rate: 20%3.2 if it is assumed that daily average total water supply flow is 140%Qn, other operating conditions are constant, we
The electrisity consumption of such situation is calculated again:
No. 1 pump is Pml=Pm=1250KW at full speed, averagely to take power
The 40% of No. 2 mean speeds, averagely taking power is Pm2=(0.4*1250) KW=500KW
The total mean power that two pumps are taken is 1250+500=1750KW
Power saving rate: 30%
Following modification scheme is established according to requirement of actual working condition and best equipment configuration:
1. the motor for being used to adjust the speed in pumping plant is changed to bis- pole three 1250kW/660V asynchronous machine, it is easy to implement perseverance
Buckling flow speed regulating control；
2. installing EI-1400K-3H variable-frequency governor additional；
3. control system configures power transformation and automatic voltage regulator；
4. fixed-voltage altering-current amount speed-regulating control device；
5. whole system combines in one movable and skid-mounted (12*4.5*2.8m).
The three, programs are compared with original control system
Using frequency control way, whole automation remote controls are totally-enclosed unattended, easy to operate, without manual
Regulating water inlet valve door greatly alleviates the labor intensity of worker, improves work efficiency.
Starting low noise, motor slowly accelerates since low frequency during startup, reach setpoint frequency after 20 seconds, by
In starting current very little, the impact to power grid is reduced, electrical equipment is protected, extend the service life of motor, improved
The efficiency of motor saves maintenance cost.
System uses one-to-one or one drag two control mode, using pressure transmitter fed-back current signals (4-20mA) to change
Frequency device central processing unit (CPU), forms closed-loop control system through PID control.The size of its output frequency is by effect processor control
System, increases or decreases the revolving speed of motor automatically；Keep work water pressure constant.
The reactive power of motor is not only reduced in this way, and improves the working efficiency of water pump, has saved the energy.
Common industrial frequency control mode (original control mode) then can not achieve such purpose, and starting and stopping needs
Want manual operation, it is also necessary to adjust the valve switch of water inlet to meet working condition requirement, i.e., it is time-consuming and laborious, and be easy to appear artificial
Factor operation error causes unnecessary loss.The revolving speed of the motor of power frequency operation control mode is uncontrollable, and is opened
Streaming current is big, needs the size of manual adjustment inlet valve to meet pressure of supply water when pressure of supply water is more than required pressure value.
At this moment motor is still with oepration at full load, and extra power just consumes on valve, and energy waste is very big.
By the analysis to the above actual condition, it is entirely capable of meeting the needs of production by the way of frequency control, so that
Water injecting pump both can big flow, can also small flow, both can high pressure, can also low-pressure operation.Utilize pressure closed loop or flow closed loop
Control water filling pressure or flow, injection station operating condition change when, frequency converter can make water injecting pump automatic adjustment water injection pressure or
Flow.At this point, the outlet valve standard-sized sheet of pump, makes the pressure difference of pump be reduced as zero.In this way, having saved electric energy, and reduce valve
Maintenance also improve the automatization level of system at the same time, reduce the noise of system, improve the environment of work, subtract
