Description
Technical field
The present invention relates to waste oil reclaiming clean technology, the useless conduction oil of specifically a kind of cementing slurry thickening experiment is returned
Receive purification system.
Background technique
The thickening time of cement slurry is the important parameter that well cementing operation is related to, and is had to well cementing operation important
Influence.The measuring of cement slurry thickening time is realized by multiviscosity meter.In the thickening experiment of cement slurry, multiviscosity meter
Corresponding heating, thickening processing are carried out to cement slurry come simulated formation temperature, strata pressure by conduction oil, to obtain water
Thickening time of the mud under specific formation temperature and strata pressure.
In the thickening experiment of cement slurry, conduction oil is contaminated due to the heating to cement slurry, so that multiviscosity meter can generate
Largely contain the oil liquid of various solid impurities and moisture impurity, these oil liquid are cannot to be directly used as multiviscosity meter again to cement slurry
Heating, thickening, it will usually make waste treatment, this certainly will by directly increase cement slurry thickening test experimental cost.
In order to turn waste into wealth, the experimental cost of cement slurry thickening experiment is reduced, attempting in the industry will be containing impurity
Discarded conduction oil carries out reclaiming clean, the conduction oil of reclaiming clean is repeated to recycle into multiviscosity meter, such as Chinese patent
" a kind of pressurizing multiviscosity meter conduction oil filter device " disclosed in document (publication number CN 207463441, publication date 06 month 2018
08 day), " a kind of thermally conductive oil treatment provisions of Portable high-temperature high-pressure multiviscosity meter " (publication number CN 207463440, publication date 2018
Year 08 day 06 month), " a kind of multiviscosity meter conduction oil reuse means " (publication number CN 207680159, publication date 08 month 2018
03 day) etc..Presently disclosed these carry out the technology of reclaiming clean to cement slurry thickening experiment with useless conduction oil, though it can go
Solid impurity in degreasing fluid, but it cannot remove the moisture impurity in degreasing fluid, purify oil liquid obtained because miscellaneous containing moisture
Matter and purity is relatively low, still cannot reliably repeat recycle into the multiviscosity meter as precision instrument.If by time that purity is relatively low
It receives purification conduction oil to be reused in multiviscosity meter reluctantly, then the accurate operation stability of multiviscosity meter can be impacted, based on thick
Change involving great expense for instrument, the operation stability of multiviscosity meter is sacrificed with the conduction oil inferior of reclaiming clean, it is real in economic cost
It is losing more than gain.
