Description
Изобретение относится к способам исследования нефтяных скважин, а именно скважин, оборудованных погружньм электронасосом, и может быть использовано в нефтяной промышленности.The invention relates to methods for researching oil wells, namely, wells equipped with a submersible electric pump, and can be used in the oil industry.
Цель изобретения - сокращение времени на проведение исследований.The purpose of the invention is the reduction of time for research.
На фиг. 1 и 2 представлена схема реализации предлагаемого способа.In FIG. 1 and 2 presents a diagram of the implementation of the proposed method.
Для проведения исследований насос 1 отключают и поднимают (опускают) до вертикального или с отклонением от вертикали не более 3е участка обсаженной трубы 2 увеличенного диаметра, выше или ниже рабочей глубины установки насосного агрегата. Известными устройствами насос 1 прижимают к стенке обсадной трубы 2 увеличенного диаметра и пропускают прибор 3 с отрезком кабеля нужной длины под насосный агрегат 1, при этом свободный конец 4 кабеля располагают выше на5 сосного агрегата. Затем насосный агрегат 1 с прибором 3 устанавливают на рабочий участок скважины и после выхода скважины на оптимальный режим известными устройствами проводят 10 механическое и электрическое соединение свободного конца 4 кабеля посредством каротажного кабеля 5 с на- 1 рземной аппаратурой, а также ‘иссле- . кования продуктивных пластов 6 путем 15 .протягивания прибора вдоль этого интервала. После проведения исследований извлечение прибора проводят в обратной последовательности.For research, the pump 1 is turned off and raised (lowered) to a vertical or deviating from the vertical no more than the 3rd section of the cased pipe 2 of increased diameter, above or below the working depth of the pump unit. Known devices, the pump 1 is pressed against the wall of the casing 2 of an increased diameter and the device 3 is passed with a length of cable of the required length under the pump unit 1, while the free end 4 of the cable is placed higher than 5 of the pump unit. Then the pump unit 1 with the device 3 is installed on the working section of the well and after the well reaches the optimum mode, the well-known devices carry out 10 mechanical and electrical connection of the free end 4 of the cable by means of a logging cable 5 with 1 surface equipment, as well as' survey. forging productive formations 6 by 15. pulling the device along this interval. After conducting studies, the removal of the device is carried out in the reverse order.
