Teager-Kaiser能量算子是一种用来分析单频信号局部离散性非线性能量密度比较有效的方法.不同类型地质体以及含油气储层将引起地震信号的能量密度产生异常,基于连续小波变换Teager-Kaiser能量就是利用这个特征进行储层预测.本文采用连续小波变换(CWT)的多尺度分辨属性和Teager-Kaiser能量算子相结合的办法进行储层预测,该方法得到的结果和20多口井的实钻资料非常吻合,能有效地刻画砂体的边界特征,平面展布和横向上的非均匀性,同时还得到一定的沉积相特征.通过理论以及实际资料分析表明基于连续小波变换Teager-Kaiser(WAVETK)能量可以作为一种有效的方法进行储层预测.
Teager-Kaiser energy operator is a more effective method to analyze the local discrete nonlinear energy density of single-frequency signals.Different types of geologic bodies and oil-bearing reservoirs will cause abnormal energy density of seismic signals, based on the continuous wavelet transform Teager-Kaiser energy is the reservoir prediction using this feature.This paper uses the combination of multi-scale CWT (continuous wavelet transform) properties and Teager-Kaiser energy operator to predict the reservoir, and the result of this method is more than 20 The real drilling data of the well are in good agreement, which can effectively characterize the boundary features, plane distribution and lateral heterogeneity of the sand body, and also get some sedimentary facies characteristics.According to the theory and practical data analysis, Teager-Kaiser (WAVETK) energy can be used as an effective method for reservoir prediction.
