摘　　要：在宋芳屯油田开发过程中,通过综合利用密测网地震资料和大量的开发钻井资料,先后研究和应用了瞬时频率和波形畸变等地震—地质砂岩预测方法,使其钻井成功率得到了明显提高。本文主要讨论波形畸变砂岩预测方法的研究过程、原理及应用条件。<ABSTRACT> Lithology prediction is a key factor to develope complex lithological reservoirs effectively. Songfangtun oilfield is one of the oilfields with lithology as the principal control- ling factor for these kinds of reservoirs. In recent yeas, by using close-line-spacing seismic data and a large amount of drilling data, seismic-geologic sand-stone prediction methods are studied and used in the development of this oilfield, including seismic reflection instanta- neous freqency method and waveform distortion method, increasing the success rate of drilling greatly. This paper mainly illustrates the studying process, principle and application conditions of the waveform distortion sandstone prediction method.
