Description
Technical field
The present invention relates to a kind of petroleum pipeline water content based on detection rectification circuit and detects control system, relates in particular to a kind of petroleum pipeline water content based on detection rectification circuit and detects control system, belongs to the prosecution field of detecting.
Background technology
At present, water content in crude oil number be to closing one of key index of both parties economic interests, although the various mineral matters in crude oil are various and complicated, but the factor that water content meter certainty of measurement is had the greatest impact is water content meter probe and hangs wax, because each crude oil paraffin content difference is added very greatly the difference of delivery temperature, thereby being produced erratically, water content meter probe hangs wax phenomenon. Hang after wax at probe, the outside cere of popping one's head in will form one deck medium to probe and crude oil, and along with the variation of dielectric layer, analyzer measured result will great changes will take place, cause measured result without any authenticity and practicality, thereby water content meter probe is carried out to paraffin removal is in time necessary.
It is the lateral opening at petroleum pipeline that current domestic most petroleum pipeline adopts moisture assay method, fix water content meter probe by ring flange, if there is hanging wax phenomenon in probe, all need be the in the situation that of pipeline shutdown, after dismounting ring flange, carry out cleaning treatment, in cleaning process, need a large amount of solvent naphthas or cleaning agent, not only strengthen cleaning cost but also polluted environment. In addition, because the stopping transportation power of examination and approval is higher, in the time that water content meter probe needs to 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 is to have increased a circulation bypass at petroleum pipeline, by crude oil by extracting out in oil transportation Trunk Line, feed back oily Trunk Line by forced circulation after circulating pump, stop valve, oil transportation bypass pipe, water content meter probe apparatus is on oil transportation bypass pipe, the method is closed stop valve in the situation that of stopping transportation not 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, cause water content meter probe to hang that wax thickness is irregular to follow, be difficult to accomplish to hang the timely cleaning of wax layer, measured data are still without much practical values.
If crude oil water content detects inaccurate, will directly affect oil well and oil reservoir dynamic analysis, destroy electric dehydration and think highly of electric field, reduce dehydrating effect, produce very large energy waste to crude oil transmission. Therefore the detection of crude oil water content is very important, always receive much attention, many measuring methods is successively proposed, design multi-form water cut test instrument, but because crude oil water content measurement is subject to the impact of many factors, and there is complicated non-linear relation with its influence factor, lack all the time a kind of not only simple and efficient, but also accurate practical forecast model.
For example application number is the online water content meter of a kind of crude oil of " 201210300479.1 ", there is a valve body with valve pocket, the oil-in and the oil return opening that are communicated with valve pocket are set on valve body, on oil-in, connect with oil circulating pump and oil inlet pipe stop valve and be connected to the oil inlet pipe of oil transportation Trunk Line, on oil return opening, connect with oil return pipe stop valve and be connected to the oil return pipe of oil transportation Trunk Line, on two relative sides of valve body, 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, stretch out outside valve body at pull bar rear portion, the fixing fluorine gum cover with centre bore of front end of pull bar, central aperture water content meter probe the size adaptation of fluorine gum cover, the rear end of pull bar is connected with push-and-pull power set. energy self-timing of the present invention, fixed ground paraffin removal, oil transportation Trunk Line does not need stopping transportation, does not need dismounting, the manual water content meter probe that cleans, and makes water content meter survey data true and accurate, makes 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 electromagnetic wave launcher, survey sniffer, analog-digital converter, processor and the actuation means of monitoring electromagnetic wave energy in medium, described sniffer connects described analog-digital converter, and described electromagnetic wave launcher, described analog-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 crude oil dehydrating plant, transfer station, measuring station, unloading Stations, oil pipeline and oil plant etc. needs the position of metering, monitoring Water in oil amount.
