Method for determining driving conversion opportunity in two-three combined development mode and related equipment

The invention discloses a driving conversion opportunity determination method in a two-three combined development mode and related equipment. The method comprises the steps that a first water drive oil extraction rate function of a first well pattern and a second water drive oil extraction rate function of a second well pattern are constructed respectively; a chemical flooding oil production rate function of the second well pattern is constructed, the chemical flooding oil production rate function is a chemical flooding oil production rate function of the second well pattern after m years of water flooding oil production, and m is the year number of water flooding oil production adopted by the second well pattern; according to the first water-drive oil production rate function, the second water-drive oil production rate function and the chemical-drive oil production rate function, performing economic benefit evaluation on the target oil field by adopting a presence-absence comparison method; and determining t
