FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, in particular, to methods of geophysical survey of wells, and is intended for determination of interval of gas flow in annular space of well on gas and gas condensate fields. Method of analyzing gas and gas condensate well includes measuring temperature along well bore and thermogram plotting before cement pouring, temperature measurement along well bore and thermogram plotting after cement pouring, at that temperature is additionally measured and thermogram is plotted after hardening of cement in 50–72 hours, followed by detecting temperature anomalies in the depth interval from the productive formation to the wellhead by analyzing the obtained thermograms.
EFFECT: high accuracy of determining the point of formation of gas flows and gas-liquid mixtures in annular space of the well from the productive formation.
