Abstract
The paper considers one of the effective methods of cleaning the well filter from various impurities and deposits – injection of hypanic acid. The technology of implementation of this promising type of treatments has been studied and the chemical compositions and their concentrations used in modern conditions of oil field development have been comprehensively studied. The results of laboratory studies to determine the optimal chemical composition for various tectonic and stratigraphic sites are presented. By screening and analyzing field experiments on injection of hypanoic acid, a number of recommendations have been formed concerning the issues of effective alignment of the pick-up profile: boundary parameters of geological and physical characteristics of productive formations have been determined, at which technological indicators of treatments will be the highest; a positive effect on the dynamics of changes in the indicator of water content of extracted products has been revealed, which significantly expands the scope of this technology. According to the results of the study, the use of this method of cleaning the bottom-hole formation zone is recommended for many deposits of the Russian Federation.
