Abstract:

The article analyzes the chemical methods for increasing the productivity of wells at OJSC TNK-Nizhnevartovsk. A brief description of the geological and technical measures is given, as well as the reasons causing the deterioration of the filtration capacity of the bottomhole formation zone. The purpose and conditions for conducting acid treatments are shown. The types of inhibitors used and their properties are considered; types of acid treatments; use of surfactants.

Keywords: geological and technical measures; purpose of acid treatments; conditions for conducting acid treatments; types of inhibitors used; types of acid treatments; surface-active substances; chemical methods to increase the productivity of wells.
