4.3.4 Signs of display of properties of wettability of collectors on change of an oil recovery and obvodnenosti chinks

1. Distinctive signs of dynamics obvodnennosti and an oil recovery on chinks of XIII horizon of deposit Uzen are:

- Fluctuations of values obvodnennosti and an oil recovery with the big amplitude during operation of chinks;

- Formation of "a stabilisation shelf" when obvodnennost and an oil recovery some time fluctuate about constants;

- Fluctuations obvodnennosti and an oil recovery occur basically in an antiphase, frequency periods out of this law however are observed.

According to representations about distribution of water and oil in emptiness of a porous medium the signs specified above testify to displays partial gidrofobizovannosti breeds of XIII horizon of deposit Uzen.

2. Distinctive signs of dynamics obvodnennosti on

To chinks are:

Changes obvodnennosti occur jumps;

Amplitude and duration of jumps the different.

At lamination of a productive layer, vertical front and replacement of oil by water under the piston schema dynamics obvodnennosti chinks will be close to described on chinks of the North Salymsky deposit.
