METHOD FOR DETERMINATION OF TECHNICAL CONDITION OF WELLS Russian patent published in 2013 - IPC E21B47/06

Abstract RU 2500886 C2

FIELD: oil and gas industry.

SUBSTANCE: method includes double recording of temperature distribution along well bore by thermal logging with two identical thermometers located at certain distance from each other along the well bore and further comparison of received temperature logs. Comparison of received temperature logs is made by their correction processing and by results of such comparison summary is made about geophysical inhomogenuities in well formations or formation influx.

EFFECT: eliminating necessity in double measurement of distributed temperature along wells axis during pumping and selection of fluid for the purpose of survey of well state.
