A well pattern that is used for fireflood of thick -layer viscous crude oil reservoir to recover oil

The utility model provides a well pattern that is used for fireflood of thick -layer viscous crude oil reservoir to recover oil. The geological structure face and the horizontal plane of thick -layer viscous crude oil reservoir form the inclination, the well pattern is arranged on the geological structure face of oil reservoir, its characterized in that: arrange and the at least oil well row of delegation including delegation's gas well in the well pattern, the gas well ranking in the high -order bit of geological structure face, the gas well in this gas well is arranged along the high -order bit of geological structure face in proper order, the oil well ranking is relative in the monoclinal structure follow the below that the gas well was arranged the direction that has a down dip of geological structure face sets gradually, two line adjacent well array parallel arrangement. The utility model provides a well pattern can full play thick -layer viscous crude oil reservoir the geological structure discrepancy i
