Abstract: Изобретение относится к области нефтедобывающей промышленности, в частности к оценке уровня жидкости в нефтяных скважинах, и может быть использовано для определения динамического уровня скважинной жидкости. Техническим результатом является создание способа способного к измерению высокоточного уровня динамической жидкости в мало- и среднетемпературных скважинах. Способ включает периодический опрос размещенных вдоль ствола скважины системы датчиков температуры, на основании данных которых формируют термограмму состояния затрубной жидкости и вычисляют градиент температуры в каждой измеряемой точке, при этом точка с максимальным значением градиента будет являться границей раздела фазовых сред жидкость-газ и соответствовать уровню динамической жидкости. При этом в затрубном пространстве скважины размещают локальные и/или распределенные источники изменения температуры затрубной жидкости, которые формируют статические зоны нагрева и/или охлаждения, а точку с максимальным значением градиента фиксируют либо в процессе нагрева или возврата к начальной геотерме, либо в процессе охлаждения или возврата к начальной геотерме, либо в процессе одновременного нагрева и охлаждения, и возврата к начальной геотерме. 3 з.п. ф-лы, 10 ил.
