The invention provides a fine-grain deposition land-phase shale crack recognition evaluation method. According to the method, a high-frequency value and a singular index in multi-scale wavelet transform are extracted from a crack sensitive logging curve, and three attribute parameters of filtering errors are predicted in an integral attribute analysis; then a difference ratio curve is constructedfrom measured well attribute model values and mean values of the same lithologic section in the same layer thereof, and three shale fracture evaluation sub-parameters of high-frequency attribute, singular attribute and prediction error attribute are determined; variation coefficient weighted average is carried out on each shale fracture evaluation sub-parameter of four sensitive well logging curves, and shale fracture evaluation comprehensive sub-parameters of different well logging attributes are determined; and finally, probability weighting coefficients are calculated from the fracture recognition probability of the three shale fracture evaluation comprehensive sub-parameters in a drilling coring segment, and shale fracture evaluation comprehensive parameters are constructed, thereby realizing the recognition of a single-well shale fracture segment and the evaluation of the fracture development degree in a fracture segment as well as providing a foundation for shale oil "sweet spot"recognition and effective development and utilization.
