FIELD: oil and gas industry.
SUBSTANCE: invention pertains to hydrology, drilling and operation of wells and it can be used for geophysical study of well integrity. Technical result is achieved due to the fact that conventional thermal log system is equipped with thermal anemometer joined with thermal system into united scheme.
EFFECT: expansion of operational functionality due to unambiguous interpretation of thermal log results for cases with temperature anomalies in the well in result of fixed temperature gradients and fluid crossflows.
