Description

Изобретение относитс  к нефт ной промышленности к может быть использовано при исследовании действукших скважин, оборудованных погружным электронасосом. Известно устройство дл  исследовани  нефт ных скважин, оборудованных погружным насосом, содержащее дистанционный прибор, подвешенный под насосдал. Дистанциоиный прибор 3 этом устройстве подвешен на каротажном кабеле, пропущенном через межтрубное пространство 1. Недостатком устройства  вл етс  трудность герметизации насосно-компрессорны труб иэ-за большого диаметра каротажного кабел . Целью изобретени   вл етс  повьпиение герметичности насосно-компрессорных труб. Указанна  цель достигаетс  тем, что устройство имеет выполненные в насоснокомпрессорных трубах герметичный токоввод и сальник, контактную полумуфту, подвижно установленную в насосно-компрес сорных трубах над насосом, и трос, приче гибкий кабель, частично уложенный в виде спирали, соединен через токоввод с контактной полумуфтой, на которой подвешен на тросе, пропущенном через сальник, прибор . На чераоже изображено устройство дл  исследсвани  нефт ных скважин, оборудованных погружным электронасосом. Дистанционный прибор I подвешен под насосем 2 на тросе 3, который пропущен через уплотнительный сальник 4 вовнутрь насосно-компрессорных труб. Электрическа  св зь осуществлена через неподвижный токоввод 5 с помсмцью гибкого кабел  6, часть которого уложена в виде спирали с возможностью раст жени  на величину интервала исследовани  скважин. Конец кабел  снабжен контактной полумуфтой 7 и совместно с тросом 3 прикреплен к нижней части полумуфты 7. Втора  по- лумуфта расположена в лсвильном устройстве 8. Работа устройства состоит в следук цем.The invention relates to the oil industry. It can be used in the study of active wells equipped with a submersible electric pump. A device for testing oil wells equipped with a submersible pump is known, which comprises a remote device suspended under the pump shaft. A remote device 3 of this device is suspended on a wireline passed through annulus 1. A drawback of the device is the difficulty of sealing the tubing of the tubing due to the large diameter of the logging cable. The aim of the invention is to seal the tightness of tubing. This goal is achieved by the fact that the device has hermetic current lead and gland made in pump-compressor pipes, a contact coupling half movably installed in the pump-compressor discharge pipes above the pump, and a cable, a flexible cable partially laid in the form of a spiral, is connected to the contact coupling half through the current lead on which it is suspended on the cable passed through the gland, the device. Figure 2 shows a device for testing oil wells equipped with a submersible electric pump. The remote device I is suspended under the pump 2 on the cable 3, which is passed through the sealing gland 4 inside the tubing. The electrical connection is made through a fixed current lead 5 with a flexible cable 6, part of which is laid in the form of a spiral with the possibility of extension by the size of the well survey interval. The end of the cable is equipped with a contact coupling half 7 and, together with cable 3, is attached to the bottom of the coupling half 7. The second coupling half is located in the loose device 8. The device consists of the following.
