摘要

碳酸盐岩储层的强非均质性加大储层横向预测的难度。在采用二步法精细标定及解释的基础上,确定储层的地震响应,并利用主成分分析振幅、频率、信噪比等多种地震属性,尤其是波形特征对TZA井区碳酸盐岩储层展布特征进行了预测,最终圈定有利储层发育区带。
The lateral prediction becomes more difficult because of the strong heterogeneity of carbonate reservoir. A measurement is presented in this paper, which determines seismic response of reservoir by horizon calibration of two-step method and seismic interpretation, predicts the distribution characters of carbonate reservoir with analysing many different kinds of seismic characters including amplitude, frequency, signal-to-noise ratio, and especially waveform, and delineates favorable reservoir zones in Tazhong A area.
