Influence of Physical and Chemical Methods of Enhanced Oil Recovery in Formation Microflora and Properties of Crude Oil

摘要

The results of the analyzes of crude oil and produced water from wells in the areas of pilot testing of new flow deflection and oil-displacing Compounds developed in the Institute of Petroleum Chemistry SB RAS. It was found that changes in the properties and Compound of the oil and water mainly occur in the redistribution of filtration flows and integration in the development of the previously unwashed areas, as well as in washing off the residual heavy oil from the reservoir rock, and in some wells - due to formation biocenosis, contributing to desorption of oil from the rock.
