Multi-factor analyzing well choosing method and device for oil field profile control

The invention discloses a multi-factor analyzing well choosing method and device for oil field profile control and belongs to the technical field of oil and gas field development. The method comprises the steps that collectable influence factors are chosen from all influence factors, and then to-be-researched influence factors are chosen from the collectable influence factors, so that obtained to-be-researched influence factor data have more pertinence; according to the corresponding oil increasing amount of the to-be-researched influence factors after profile control and well choosing indexes of a well subjected to profile control, a well choosing index model is obtained; according to the weighing score of each to-be-researched influence factor of the to-be-researched profile control well and the highest weighing value corresponding to the weighing score, the well choosing index of the to-be-researched profile control well is obtained; and the well choosing index of the to-be-researched profile control well is substituted into the well choosing index model to determine profile control of the to-be-researched profile control well, well choosing guiding in the practical on-site application process is achieved, and high practicability is achieved.
