Yidong fault zone is rich in oil and gas,and the exploration space of the tertiary lithology body is large,but the exploration degree is low.The main reason restricting the exploration efficiency is that the reservoir heterogeneity is strong and the distribution rule is complex.At the same time,due to the limitation of seismic data and conventional seismic prediction technology,the favorable reservoir seismic prediction of lithologic body is difficult.Based on the high density three-dimensional azimuth seismic data of YD area,the authors carried out the research on the favorable reservoir seismic prediction of the fourth member of Shahejie Formation.Firstly,the difference of azimuth seismic properties was used to predict the distribution of fractures in the reservoir.Then the anisotropic reservoir prediction technique based on anisotropic parameter inversion was used to describe the anisotropic characteristics of the reservoir.Finally,combined with the results of two kinds of seismic prediction techniques,with the fracture distribution as the main predicted object and the reservoir anisotropy characteristic as the restricted condition,the authors described the fracture development degree of the limestone reservoir in the fourth member of Shahejie Formation comprehensively and improved the prediction accuracy of the favorable limestone reservoir in the fourth member of Shahejie Formation.
