中文摘要：

时频分析是地震数据处理与解释中的一种重要的技术手段.笔者把该技术应用于吉林某油田中,得知研究区内储层主要由两个朵叶构成,分别位于该油田的西北部和西南部.地震反射波的85％能量位置对应的频率、65％能量位置对应的的频率和45 Hz位置的能量百分比,三个时频属性可确定砂岩的分布范围,有利储层发育程度和分布范围,并给出了有力并位,和钻井情况一致.

英文摘要：

Time-frequency analysis is an important technology of seismic data processing and interpretation.This technology has been applied in a certain oilfield of Jilin,and the research results show that the reservoir layer of this region includes two lobes which are located in the northwest and southwest of the oilfield.The frequencies corresponding to 85％ and 65％ of the seismic reflection wave energy and the frequency located in 45 Hz can determine the distribution of sandstone,which is favorable for the reservoir in development degree and distribution range.This research provides the most favorable location of wells which agree to the drilling information.
