摘　　要：本文针对研究区Z2地区储层埋深大,地下地质条件复杂等特点,结合沉积相,应用三种地震储层预测技术进行研究。结果表明,地震属性技术对于Z2地区储层平面展布特征的刻画较为清晰;约束稀疏脉冲波阻抗反演技术对于纵向上精细划分储层效果显著,但在Z2地区的应用效果较差,纵向分辨率较低,难以准确预测砂体;地质统计学反演则可以提供研究区高分辨率的砂泥岩预测结果。Seismic reservoir prediction is becoming more and more widely used in oil and gas exploration.Seismic attribute technique,constrained sparse pulse impedance inversion and geostatistical inversion are all effective methods for reservoir prediction.Based on the characteristics of reservoir buried depth and complicated geological conditions in the Z2 area,the authors studies three kinds of seismic reservoir prediction techniques in combination with sedimentary facies.The results show that the seismic attribute technique is favorable to the characterization of the reservoir plane distribution for the Z2 area.The constrained sparse pulse impedance inversion technique is effective for the vertical division of the reservoir,but its application effect is poor,the vertical resolution is low and it is difficult to predict the sand body accurately.The geostatistical inversion can provide high-resolution sand and shale predicting results in the study area.
