The invention discloses a porosity evolution recovery and physical property prediction method for a complex area reservoir. The porosity evolution recovery and physical property prediction method comprises the steps 1, partitioning and segmentation are performed under the condition that main reservoir physical property controlling factors are determined based on porosity evolution; 2, hole and seepage data is actually measured according to geological conditions; 3, a hole and seepage evolution model about porosity, permeability and deep burying change is established; 4, for the influence existing in the western deep water area of the south China sea due to different water depth conditions and differential rock compaction, shallow layer sand/mud rock compaction correction is conducted on water depth, further a correction layer stratum is applied to deeply predict burying depth lower limits of physical characteristics in areas different in water depth condition and the corresponding depth physical characteristics. According to the method, porosity and permeability evolution models with compaction as porosity evolution main controlling zones and relevant to early-stage overpressure, later-stage overpressure, early-stage hydrocarbon charging protection or later-stage dissolution improvement and different water depth conditions are established, real drilling shows that porosity errors are about +/-1%, and the permeability is in a prediction range.
