THEORETICAL BASIS OF USE ORGANOSILICON COMPOUNDS FOR REPELLING SURFACE

 

Background

Capillary end effect is a highly relevant problem of oil development from low-permeable reservoirs because of highly wetted bottom-hole zone. According to theoretical investigations increase of capillary water in the low-permeable bottom-hole zone decreases the oil development in over 2 times in the same pressure conditions. Essentially it will complicate the oil development.  

Aims and Objectives

To prevent the capillary end effect and to increase the oil development.

Methods

Theoretical and laboratory studies of usability of organosilicon compounds for porous reservoir surface repelling.

Results

It was established that «Polisil» solution decreases the relative water permeability. The permeability before and after differs in 13 times. In addition to that, solutions based on the LPG are better in water relative permeability decrease that solutions based on the tarry asphaltene substances. In spite of that, the second solution is better in water replacement so that reservoir coverage increases.

 

Key words: organosilicon compounds, surface hydrophobization.
