The situation of oily sludge solution in device display device, filter screen can filter out the oily sludge and match that roping comes
Grain size in the oily sludge solution made larger solid phase particles and " dead fish eye ", effectively avoid holddown even termination of pumping
The generation of phenomenon, while ensure that the quality of oily sludge solution.Sludge single screw rod delivery pump has simple in structure, work
Make it is safe and reliable, easy maintenance, go out the advantages that liquid continuous uniform, pressure stability, when pumped (conveying) medium, does not form vortex, to Jie
The viscosity of matter is insensitive, therefore, conveying is suitble to contain solid particle and the very high thick liquid of viscosity.Simultaneously as containing
Greasy dirt injection pump plug radius is big, and plunger motion speed is slow, and abrasion is small, so the time between overhauls(TBO) is very long, and can be used for noting
Enter the liquid medium containing hard particles, in this way, by the synergistic effect of each device feature, makes the injected system rate of breakdown
Low, the time between overhauls(TBO) is long, finally meets oily sludge profile control and water plugging large dosage, small displacement, long-time continuous operation construction requirement.
2, the intelligent injected system of oily sludge profile control and water plugging of the present invention, can be controlled by frequency converter and be adjusted containing greasy dirt
System parameters data can be constantly monitored and controlled by remote data acquisition control system, simultaneously in the flow of mud injection pump
The open and close that each electrically operated valve, agitating device, screw pump motor etc. can be controlled, to realize remote monitoring and operation,
Realize that large dosage of oily sludge profile control and water plugging intelligently injects.
3, the intelligent injected system of oily sludge profile control and water plugging of the present invention, by optimization design, flow is simple, operation side
Just, high degree of automation, the time between overhauls(TBO) is long, and labor intensity is low, while this injected system is designed using skid, compact-sized, removes
Fortune facility, operating cost are low.
4, electronic flowmeter shows that the conveying discharge capacity of screw pump, level monitor show medicine in liquid dispensing device and device for storing liquid
The liquid level of agent solution, filter screen filtration are fallen in the oily sludge and prepared oily sludge solution that roping comes
The larger solid phase particles of grain size and " dead fish eye " effectively avoid the holddown even generation of termination of pumping phenomenon, while ensure that containing greasy dirt
The quality of mud plugging agent solution, electronic flowmeter show the discharge capacity of screw pump and oily sludge injection pump, are adopted by remote data
System parameters data can be constantly monitored and controlled in collection control system, while can control each electrically operated valve, agitating device, spiral shell
Remote monitoring and operation may be implemented by the synergistic effect of each device in the open and close of bar pump motor etc., big to realize
Dosage oily sludge profile control and water plugging intelligently injects.
The above, only specific embodiments of the present invention, the range that cannot be implemented with its restriction invention, so it is equivalent
The displacement of component, or according to equivalent variations made by scope of patent protection of the present invention and modification, should all still fall within what this patent was covered
Scope.In addition, between technical characteristic and technical characteristic in the present invention, between technical characteristic and technical solution, technical solution with
Use can be freely combined between technical solution.
