FIELD: oil and gas industry. ^ SUBSTANCE: invention includes discharges of tube and after-tube channels of the well, which are made in tubing wellhead. To the first discharge of after-tube channel there connected is gas cleaning line on which the control device is installed and which is connected to the inlet of gas cleaning device. Gas cleaning device is provided with possibility of cleaning and degassing of produced water and its outlet is connected to purified gas discharge line, and liquid output with produced water discharge line to utilisation, which is connected to the first discharge of the well tube channel. The second discharge of after-tube channel is equipped with echo sounder-level metre and sealing assembly of cable of bottom-hole pressure gauge. The third discharge of after-tube channel and the second discharge of tube channel are equipped with quick-detachable connection assemblies. In the third and the fourth discharges of tube channel there installed are devices for fixing of polished rod of the well pump. As per the second version, produced water cleaning device is mounted on produced water discharge line to utilisation. As per the third version, there is discharge line of non-cleaned gas to the torch, which is attached to the third discharge of after-tube channel and interconnected with gas cleaning line. Produced water cleaning line is connected to produced water degassing and cleaning device, and its gas discharging device is interconnected with discharge lines of cleaned and non-cleaned gas to the torch. ^ EFFECT: simplifying the design and enlarging functional capabilities. ^ 34 cl, 3 dwg |
