Способ определения заколонных перетоков, включающий регистрации серии термограмм в различных режимах работы скважинного насоса, причем наличие затрубных перетоков определяют по темпу изменения температуры, отличающийся тем, что исследования проводят при работающем штанговом насосе и при остановленном штанговом насосе в режиме притока, начиная с забойного давления выше давления насыщения пластового флюида газом, далее в интервалах температурных аномалий и ниже перфорированных интервалов определяют зависимости температуры от давления и выделяют участки с обратной зависимостью, которые характеризуют заколонные перетоки снизу вверх. A method for determining annular flows, including recording a series of thermograms in various operating modes of the well pump, the presence of annular flows being determined by the rate of temperature change, characterized in that the studies are carried out with the sucker rod pump running and with the sucker rod pump stopped in the inflow mode, starting from the bottomhole pressure above the pressure of saturation of the formation fluid with gas, then in the temperature anomaly intervals and below the perforated intervals, the pressure dependences of temperature are determined and sections with an inverse relationship are identified that characterize casing flows from the bottom up.
