Analysis of the factors, determining the efficiency of hydrophobiation of producing wells bottom zones

Authors: A.M. Svalov (Oil and Gas Research Institute of RAS, RF, Moscow)

Key words: hydrophobization face zones, layered heterogeneity, anisotropy filtering properties.

The factors, determining the effectiveness of hydrophobization of producing wells bottom zones to reduce production watering, are analyzed. It is shown, that to achieve a positive effect it is necessary to consider the ability of the used reagent to plug the pore space at interaction with water. Stratified heterogeneity of productive strata, sector character of the formation fluid movement in the well bottom zone and the anisotropy of the filtration properties of rocks, caused by stratification of its microstructure, are essential.
