Abstract

​

​One of the ways to optimize matrix acidizing is its physical modeling under simulated reservoir conditions. The paper discusses the results of laboratory modeling of matrix acidizing during core flood tests using unique acid systems. Based on set of studies, various options of acidizing optimization are offered considering reservoir differentiation in terms of porosity and permeability and with regard to possibility of acid system properties control.

Key words:

​

rapid analysis, acidizing, flood test, properties control, injection rate, rate of reaction, stimulation optimization
