Abstract
Способ определения глубины погружения скважинного прибора, включающий предварительный промер каротажного кабеля с нанесением на броню кабеля магнитных меток через заданные отрезки, запоминание сигнала, соответствующего длине отрезка, спуск в скважину закрепленного на конце каротажного кабеля скважинного прибора, обнаружение наземным регистратором магнитных меток при спуске-подъеме кабеля в процессе геофизических исследований, подсчет обнаруженных магнитных меток и определение по их количеству глубины погружения скважинного прибора, отличающийся тем, что параметр глубины погружения скважинного прибора определяют как функцию текущего времени погружения с учетом скорости перемещения каротажного кабеля, измеряемой одновременно с геофизическими параметрами скважинного прибора и вычисляемой по формуле:где t- текущее время, регистрируемое в процессе геофизических исследований, мин,R - радиус мерного ролика,- угловая скорость вращения мерного ролика.A method for determining the immersion depth of a downhole tool, including preliminary measurement of the wireline with magnetic marks applied to the cable armor through predetermined sections, storing the signal corresponding to the length of the section, descent of the downhole tool fixed to the end of the wireline of the downhole tool, detection of magnetic marks by the ground recorder during descent cable in the process of geophysical research, counting detected magnetic marks and determining by their number the depth of immersion of the downhole tool ra, characterized in that the parameter of the depth of immersion of the downhole tool is determined as a function of the current time of immersion taking into account the speed of movement of the logging cable, measured simultaneously with the geophysical parameters of the downhole tool and calculated by the formula: where t is the current time recorded in the process of geophysical exploration, min, R is the radius of the measuring roller, is the angular velocity of rotation of the measuring roller.
