Description
Technical field
The present invention relates to a kind of alcohol concentration detecting device, particularly relate to a kind of high precision petroleum pipeline water cut inspection and control system, belong to alcohol concentration prosecution field.
Background technology
At present, water content in crude oil number be to one of key index closing both parties economic interests, although various in crude oil
Mineral matter is various and complicated, but water content meter probe is to the factor that water content meter measuring accuracy has the greatest impact and hangs wax, because each crude oil wax content difference adds very greatly the difference of delivery temperature, thus water content meter probe is made to produce extension wax phenomenon erratically.After probe hangs wax, the cere of probe outside will form one deck medium to probe and crude oil, and along with the change of dielectric layer, analyzer measured result will great changes will take place, cause measured result without any authenticity and practicality, it is necessary for thus carrying out paraffin removal in time to water content meter probe.
Current domestic most pipe laying adopt moisture assay method to be lateral opening at pipe laying, water content meter probe is fixed by ring flange, if probe occurs hanging wax phenomenon, all need when pipeline shutdown, cleaning treatment is carried out after dismounting ring flange, in cleaning process, need a large amount of solvent oil or clean-out system, not only strengthen cleaning cost but also pollute environment.In addition, because the stopping transportation power of examination and approval is higher, when water content meter probe need clean, as can not granted stopping transportation, now data that water content meter is surveyed have no value for use completely, and therefore, this type water content meter is deadlock state substantially.Another kind method adds a circulation bypass at pipe laying, crude oil is extracted out by oil transportation Trunk Line, oily Trunk Line is fed back by forced circulation after ebullator, stop valve, oil transportation by-pass pipe, water content meter probe apparatus is on oil transportation by-pass pipe, the method closes stop valve when on-line production just can pull down cleaning to water content meter probe, but because the number of the content of wax in crude oil alters a great deal, wax thickness is irregular to follow to cause water content meter probe to hang, be difficult to the timely cleaning of accomplishing to hang wax layer, measured data are still without much practical values.
If crude oil water content detects inaccurate, directly will affect oil well and oil reservoir performance analysis, and destroy electrical dewatering and think highly of electric field, reduce dehydrating effect, produce very large energy dissipation to crude oil transmission.Therefore the detection of crude oil water content is very important, always receive much attention, successively many measuring methods is proposed, design multi-form water cut test instrument, but because crude oil water content measurement is subject to the impact of many factors, and with its influence factor, there is complicated nonlinear relationship, lack a kind of not only simple and efficient, but also accurately practical forecast model all the time.
Such as application number is the online water content meter of a kind of crude oil of " 201210300479.1 ", there is one with the valve body of valve pocket, valve body arranges the oil-in be communicated with valve pocket and oil return opening, oil-in connect with circulating oil pump and oil inlet pipe stop valve and be connected to the oil inlet pipe of oil transportation Trunk Line, oil return opening connect with scavenge pipe stop valve and be connected to the scavenge pipe of oil transportation Trunk Line, on two sides that valve body is relative, one of them lateral means water content meter is popped one's head in and another lateral means pull bar, water content meter probe front portion and pull bar front portion are stretched in valve pocket, pull bar rear portion is stretched out outside valve body, the fluorine gum cover with center pit is fixed in the front end of pull bar, the central aperture water content meter probe also size fit of fluorine gum cover, the rear end of pull bar is connected with push-and-pull propulsion system.Energy self-timing of the present invention, fixed ground paraffin removal, oil transportation Trunk Line does not need stopping transportation, does not need dismounting, manual cleaning water content meter probe, makes water content meter survey data true and accurate, make crude oil simple and reliable containing aquametry online.
And for example application number is a kind of Water in oil monitor of " 201220676751.1 ", comprise the sniffer of electromagnetic wave energy in electromagnetic wave launcher, detection monitoring medium, analog to digital converter, processor and actuation means, described sniffer connects described analog to digital converter, and described electromagnetic wave launcher, described analog to digital converter, described actuation means are all connected with described processor.Above-mentioned Water in oil monitor is both simple and efficient, accurately practical again.Can be widely used in the position that crude oil dehydrating station, transfer station, test satellite location, unloading Stations, oil pipeline and refinery etc. need to measure, monitor Water in oil amount.
