FIELD: mining.
SUBSTANCE: proposed method for determination of annular seal integrity in well includes several stages. At the first stage provided is characteristical response related to geological formation, providing efficient annular seal around section of casing pipe located in well. At the second stage at least one well-logging tool is lowered into selected well passing through geological formation in order to get response data related to geological formation property. At the third stage response data from selected well is compared to characteristical response in order to determine creation of efficient annular seal by geological formation around section of casing string located in selected well.
EFFECT: lower labour costs for provision of high-quality sealing of tubular annulus in well.
