| description | The invention relates to a quantitative prediction method for an internal structure of a biological reef reservoir body. The method comprises the following steps: acquiring petroleum seismic data and interpretation result data thereof in a certain biological reef body range; calculating a difference entropy seismic attribute, a homogeneity seismic attribute and a stratum quality factor attribute of a target interval according to data obtained by petroleum seismic exploration; calculating the characteristic index R of the internal structure of the biological reef in the range of a certain biological reef body to be predicted; counting the threshold value of the characteristic index R of the biological reef found by drilling in the area and dividing the internal structure of the biological reef; comparing the calculated data of the characteristic index R of the internal structure of the biological reef in the range of the certain biological reef body to be predicted with the threshold value R, namely Rgt; if R |
