【Abstract】 In allusion to the structural characteristics of carbonate reservoirs in the areal coverate of upper Ordocician of Tahe Oilfield, based on the analysis of geologic, well drilling, logging and production testing data and seismic response, the methods of recognition and prediction of voggy reservoirs in Yijianfang Formation were studied. The study indicates that attribute extracting technique is appropriate for inner karst cave prediction in Yijianfang Formation; the surface reservoir is predicted by using the method of fine waveform classification in combination with seismic waveform analysis and reflection mechanism,the characteristic waveform in the fracture growth intervals are summarized, the response pattern between the reservoir and seismic waveform is established, the fine classification of reservoirs is determined, and reservoirs in the unknown domain are predicted based on fitting criterion and eventually spatial distribution of seismic reflection of favorable reservoirs is obtained. Application shows that the method is feasible.更多还原
