The conventional synthetic record calibration technique can not satisfy fine reservoir prediction and precise structural interpretation. The technology of high-precision wavelet frequency division calibration was first adopted, and new technologies and methods that include frequency division of fine well|to|seismic calibration and frequency division geological calibration were carried out with the integration of seismic and geological information. The accuracy of well-to-seismic calibration is improved step by step, wavelet uncertainty on the impact of well-to-seismic calibration was overcome, the traditional way dependant on the coefficient of calibration to distinguish calibration results was broken, and the seismic and geological information were organic combined to reduce the calibration uncertainty. In practical applications, under complicated geological conditions such as thin interbeds of sandstone and shalestone complex wave, complex lithology combination, reservoir change rapidly in lateral, seismic reflection characteristics unclear, this method has gained good effects in fine well seismic calibrations.
