4.3.2 Features of behaviour of an oil recovery and obvodnennosti layer production on chinks of XIII horizon in comparison with chinks of the North Salymsky deposit

For revealing of prominent features of behaviour of indexes of work of chinks, we had been analysed data on some chinks of XIII horizon. In drawings 4.9 - 4.12 graphs of change of a relative monthly oil recovery (in relation to maximum) and obvodnennosti depending on current selection of a potential oil recovery from a chink for all operating time are resulted

(Potential extraction was taken over to the equal saved up extraction for the analyzed period of operation).

The chink № 0002 was one of the first, opened up on a deposit. On this chink long enough anhydrous period during which splashes obvodnenosti small amplitude were marked is observed.

Comparison of graphs on chinks allows to reveal some features of work of chinks. The first prominent feature of change of indexes consists in kolebatelnosti obvodnennosti and an oil recovery

In very wide limits, and these fluctuations basically occur in an antiphase. The second feature consists that "stabilisation regiments" are formed at obvodnenosti from 45 to 75 % on chinks. The third feature consists that the oil recovery can increase in times, is not dependent on behaviour obvodnenosti, that testifies to changes of a filtration field in a layer round chinks. We will notice, that around an arrangement of analyzed chinks it was made zakachka Union of Right Forces.

In drawing 4.13 change graphs obvodnennosti and a relative annual oil recovery depending on a share of the selected potential extraction on chinks of the North Salymsky deposit which productive layer differs a homogeneous structure on beds are presented. Character of change sharply differs from the resulted graphs on Uzeni. Change obvodnennosti occurs jumps in process of the approach

Comparing the specified distinctivenesses of change obvodnennosti on chinks of Uzensky and North Salymsky deposits with the representations resulted above about distinctivenesses of working out of layers with mainly hydrophilic and hydrophobic properties, it is possible, probably to assume about influence of properties of wettability of collectors on change of indexes of work of chinks of these deposits.
