Abstract:Since thu sand body reservoir have influence on seismic reflected signals in time and frequency and wavelet rranslorm can just reflect the time and frequency components of signals,therefore,the paper uses wavelet transform to analyze the time-frequency feature oi seismic records.In view of the caapability of locally analyzing the signals and providing multi -scale wavelet coefficients that the wavelet transform has.so the wavelet transform can finely be used for reservoir prediction.The wavelet coefficienis can be taken as measuring the time-frequency featurte of signals that could be further demonstrated by tests of tht,theoretical models.The paper presented the wavelet parameters of seismic signals being laken as a new kind of seismic attributes,i.e.wavelet attributes.The map of seismic attributes of the targets can be acquired in practice where the lateral variation of reflected feature oi targets is known and distribution of revser-voirs is detected.The paper considered that like other seismic atrributes parameters.the wavelet attributes belong to multi-attributes analysis.
