NEW EFFECTIVE CHEMICAL DESTRUCTORS ELIMINATING RESERVOIR POLYMERIC CONTAMINATION (BLOCKADE) DURING WELL PRIMARY UNCOVERY AND OVERHAUL
HV and DT chemical compositions of polymer contamination destructors are developed by the author of the present article. Some studies of viscosity changes in time of the most frequently used polymers under the influence of developed reagents were made. Destructors are recommended for cleaning of pore space from polymer contamination after well secondary development or overhaul by setting long-term baths or making multiple washouts of formation bottom hole. Complete absence of corrosion aggressiveness of the developed chemical destructors allows their usage in production wells without negative consequences which may be caused by hydrochloric acid treatment.
