Abstract

Способ обнаружения заколонных перетоков жидкости в скважинах, основный на измерениях акустических сигналов, отличающийся тем, что проводят измерения естественных геоакустических сигналов вдоль оси обсаженной колонной скважины тремя ортогонально расположенными датчиками, ось чувствительности первого из которых совпадает с осью скважины, второй и третий направлены перпендикулярно к ней, определяют величину отношения амплитуд сигналов первого датчика к корню квадратному из суммы квадратов амплитуд сигналов второго и третьего датчиков, при наличии заколонного перетока экспериментально установленная величина отношения должна быть не менее 0,8.A method for detecting annular fluid flows in wells, based on measurements of acoustic signals, characterized in that they measure natural geoacoustic signals along the axis of the cased-hole casing with three orthogonally located sensors, the sensitivity axis of the first of which coincides with the axis of the well, the second and third are directed perpendicular to it , determine the ratio of the amplitudes of the signals of the first sensor to the square root of the sum of the squares of the amplitudes of the signals of the second and third sensor in, if casing flow experimentally established the ratio should be at least 0.8.
