FIELD: mining.SUBSTANCE: invention is intended for placement of well pressure and temperature sensors included in underground well equipment. Design combines housing, unit of submersible cable supply and adapter. Inside the housing a setting device is made, in which there is a metal tube with a sensor. On one side housing is connected with adapter with external thread for connection with housing and internal thread for connection with device. Device comprises sealing unit consisting of seals for device sealing with adapter and sealing rings, arranged in series, and covering the tube. Device comprises unit of protection from shock effects in form of extended spiral channel formed by thread of the device and union. On the other side housing is connected to cable unit comprising device for external fixation of cable and an internal channel for cable supply. Cable is equipped with sealing unit, comprising sealing rings arranged in series and covering it. Mechanism of fixing housing on adapter is placed on the unit. Adapter has holes for fastening elements and is equipped with a channel for communication of sensor with space inside the tubing string.EFFECT: technical result consists in improvement of reliability of underground equipment and increasing protection of the sensor.1 cl, 4 dwg |
