Beschreibung
Zusammenfassung:	FIELD: mining. ^ SUBSTANCE: facility consists of two-channel head control, packer installed between upper and lower formations, main flow string connected with lower formation and additional flow string. According to the invention when pressure during water pumping into the upper formation exceeds the value of allowed pressure for the flow string, an additional packer is installed above the upper formation. The additional flow string is assembled in a borehole parallel to the main one and is connected to the latter by means of two-channel anchor; the additional flow string is coupled with the anchor by means of a movable sealed connection. ^ EFFECT: simplification of design, protection of flow string, possibility of formations evaluation and reduced metal consumption of facility. ^ 4 cl, 4 dwg
