METHOD DEVELOPMENT thermal mining fractured DEPOSIT OF HIGH OIL

摘要

1. The method for thermal mining development cracked heavy oil deposits, comprising driving of a drilling gallery at the bottom or below the oil reservoir, and selecting download coolant oil through underground gently sloping, steeply inclined and vertical wells, injecting displacing agent after heating the formation to the optimum temperature, characterized in that and high-angle wells are drilled vertical wells gently sloping from bottom to top in the form otvodov.2. A method according to claim 1, characterized in that the tapped gently sloping wells interleaved with gently sloping wells without otvodov.3. A method according to claim 1, characterized in that in the initial period leads coolant through injection wells without bends gently sloping, and the selection of oil through wells gently sloping otvodami.4. A method according to claim 1, characterized in that the tapped hole, which is not sufficient to respond to the coolant injection, equipped with a packer tubing, cut-off outlets from the main stem, and the coolant is pumped through tubing to the taps, while selecting the oil through the annular prostranstvo.5. A method according to claim 1, characterized in that after heating the formation to a temperature optimal lead download displacement agent through the hole tapped gently sloping, and the selection through the oil gently sloping wells without bends.
