The observation of observation window 21 is crossed, after the completion of rock core destructive distillation, stops heating of the microwave generator 6 to rock core, reads at this time cold in measuring bottle 97
The volume of lime set body, i.e. rock pore volume VHole；
4, chloride ion, sodium ion and potassium ion are measured and reaches that ion of concentration balance at first in deionized water at this
Ion concentration ρ in water flooding where rock coreGround is surveyed；
5, according to formula SW=VWaterρIt surveys/VHoleρGround is surveyed, calculate the value of rock core water containing saturability, wherein
SW: rock core water containing saturability (%), VWater: deionized water volume (unit: L)；ρIt surveys: reach at first in deionized water dense
Spend the concentration (unit: mg/L) of the ion of balance；VHole: rock pore volume, i.e., by measuring bottle 97 measure from rock core hole
The volume (unit: L) for the liquid that middle destructive distillation goes out；ρGround is surveyed: the ion pair for reaching concentration balance in deionized water at first should be in water flooding
In the ion concentration (unit: mg/L).
Rock core water containing saturability measuring device of the invention, the microwave that microwave generator 6 generates is in upper reflecting plate 3 under
It reflects, the rock core held in rock core container 5 can be heated between reflecting plate 8, heating efficiency is high, and can promote
Spread the ion in rock core pore water quickly；In addition, stepper motor 71 drives rotating base 7 and rock core container 5 slow
Rotation so that rock core it is heated more uniformly；Further more, be connected by the interface 23 that vacuumizes on shell 2 with vacuum pump 100,
On the one hand rock core internal gas is extracted out, so that deionized water and rock core pore water directly contact, further promotes deionized water
Rock core is immersed, convenient for the diffusion of rock core pore water intermediate ion, on the other hand, the heating of rock core under vacuum conditions is realized, into one
Step improves heating efficiency and promotes the quick diffusion of rock core pore water intermediate ion；It is measured simultaneously using three kinds of ionometers 32, it can
To save the time, improve efficiency.When carrying out destructive distillation to rock core, replacement instrument is not needed, condensing unit 9 is directly accessed, one
Change test, measuring process is few, and accuracy is high.
The foregoing is merely the schematical specific embodiment of the present invention, the range being not intended to limit the invention.It is any
Those skilled in the art, made equivalent changes and modifications under the premise of not departing from design and the principle of the present invention,
It should belong to the scope of protection of the invention.
