1.1.5 Residual oil in deadlock pores and micronon-uniform zones

Deadlock pores from the hydrodynamic point of view are hold-up spots, and in them the displacement process neither under the influence of hydrodynamic, nor under the influence of capillary forces is not possible.

In these pores are possible only slow massoobmennye processes with flowing pores.

With the mixed type of wettability these deadlock pores contain residual oil which on the properties can be similar to natural oil in hydrophobic layers and layers and allocation of this residual oil in a separate category is expedient.

The sizes of deadlock pores, as a rule, are small, however, deadlock pores and partially substituted pores of leaching, insignificant cavities are possible the significant sizes etc. At presence, such pores ONN of deadlock pores can be formed and in hydrophilic collectors. A share

ONN in deadlock pores grows with deterioration of permeability of a collector. V.I.Tulbovicha's by works it is shown, that for terrigennyh and carbonaceous breeds there are correlation dependences between a share of deadlock pores and the permeability logarithm. There is also a communication between factor of tortuosity and a share of deadlock pores which represents a return exponential law [31,32,33].

As it was specified, the quantity of micropores in a collector can be connected from it litologicheskim composition [34,35]. In this case for collectors with evenly distributed clay material the share of deadlock pores is defined by quantity of clay cement and its porosity [35].

In treshchinno-ttorovyh layers of a pore of the block are actually to a floor deadlock in relation to treshchinnoj porosity. A similar situation in breeds with malopronitsaemymi inclusions. In such breeds in malopronitsaemyh sites actual residual oil is formed.
