Abstract | FIELD: mining. ^ SUBSTANCE: device includes wellhead, injection tubing made of hollow compressor pump pipes of lesser diametre positioned concentrically in compressor pump pipes of larger diametre with heat-resistant packer stopping operational column over the stratum. Lower part of compressor pump pipe string of larger diametre carries a cylinder and nipple in downside sequence, the nipple being equipped with poppet valve, self-sealing packer and protection casing with traverse rod passing through longitudinal nipple holes. Injection string shoe features hollow plunger in the form of a pin with sealing rings and is positioned in the internal cylinder cavity so as to actuate plate valve, while the plate valve rod actuates protection casing of self-sealing packer over the traverse rod. Lower sealed end of the hollow plunger is conical and has side holes. Injection string features centering skids made of non-heat conducting material. ^ EFFECT: increased thermal stratum processing efficiency due to minimisation of heat loss in the well hole during heat carrier injection. ^ 3 dwg |
