Annotation:

The industrial replication of acid treatment technology using deflection systems at the fields of the Perm Territory is analyzed. As the main applied technology, treatment of the bottomhole formation zone was chosen, during which a reverse hydrophobic emulsion is used as a diverter. The basic principle of this acid treatment application is described. Based on the results of the analysis of the work performed in 2017–2020, the main parameters influencing the success of acid treatments with the use of diverters were determined, they are as follows: effective oil-saturated thickness, number of previous treatments, ratio of volumes of acid and diverter, specific costs of acid composition. The success of acid treatments, using deflection systems, is expressed in the initial increase in oil production rate, as well as in the specific additional oil production.
