Kernoderzhatel installations allows to pump over liquid through samples of a core both in the direct and return directions, and along a core end face for formation of a kolmatatsionny crust, modeling conditions of adjournment of firm particles on a well wall.
In installation the possibility of connection to 4 ports of measurement of differential pressure with simultaneous measurement of electric resistance on these points is provided (the distance between ports can be chosen randomly).
Boring solutions are in special containers at reservoir pressures and temperature. Containers provide continuous hashing of drilling mud fluid for prevention of subsidence. By the additional order all parts of installation contacting to fluids can be made of acidproof chromonickel alloys (HASTELLOY® C-276) for studying of currents of acids the, and other aggressive liquids entered into layer.Opportunities The PIK-OFP-FD complex allows to determine the following parameters of a core:
- permeability on liquid;
- studying of influence of fine particles;
- sensitivity of layer to acids and alkalis;
- assessment of the inhibiting acid processing.
