Description
Technical field
The present invention relates to oil field reinjection water water quality monitoring fields, more particularly to one kind to be used for oil field reinjection water suspended matter partial size
A kind of application of the laser particle analyzer of on-line monitoring and laser particle analyzer in oil field reinjection water suspended matter partial size on-line monitoring.
Background technique
After the investment exploitation of oil field, oil reservoir energy itself will be constantly consumed, and cause formation pressure constantly to decline, underground
Crude oil largely deaerates, and viscosity increases, and oil well output greatly reduces.In order to keep or improve formation pressure, higher harvesting is obtained
Rate, it is necessary to which oil field is filled the water.
It is largely oil field reinjection water used by oil-field flooding at present.If cannot find that suspended matter partial size does not reach in time
Target reinjected water is easy for blocking formation core, leads to the oil field underproduction.Therefore, it is necessary to carry out on-line checking to reinjected water.At present
Laser particle analyzer type is more, and most of is all use for laboratory instrument, offline inspection successively carries out field sampling, seals up for safekeeping, is real
Test room chemical examination, record data, feed back on-site.External particle size analyzer manufacturer starting is more early, and occupation rate of market is high.Comparative maturity has English
The Malvern (Malvern) of state, the Kurt (Coulter) in the U.S., French hila think (Cilas) company, German new bus too
Library (Sympatec), HORIBA company, Japan.Wherein the laser particle analyzer of Malvern company China's Mainland occupation rate most
It is more, it manufacture Mastersizer series particle size analyzers, single range, measurement particle size range be 0.02~2000 μm, can do wet process and
Drying measure.The development of domestic laser particle analyzer starts from the late nineteen eighties in last century, achieves certain progress in recent years, at present
Domestic many universities and research institution have all carried out the research of light scattering laser granularity Detection, such as University Of Chongqing, south China teacher successively
Model university, University Of Tianjin, Institutes Of Technology Of Nanjing, Shanghai ray machine institute, Harbin Institute of Technology etc..Occur Zhuhai " American-European gram ",
Jinan " micro-nano ", " essence new " in Chengdu, Dandong a series of manufacturers such as " hundred is special ".In measurement range, the repeatability of measurement, granularity
The Key Performance Indicators such as resolving power, reliability on still have certain gap with external product.
These existing instruments have problem jointly: whole process analytical cycle is long, not can be carried out on-line checking；Outer dimension
It is larger, do not have water-proof function, cannot be placed in filling pipe.
