摘要：

根据胜坨油田气藏分布浅(15秒以上)、构造简单、地震品质好的特点,结合钻井资料,选取了振幅、瞬时频率、瞬时相位3个参数,分析了它们与已知气层的对应关系。钻井显示的含气层段在振幅属性剖面上表现为强振幅,瞬时频率剖面上为低频率,瞬时相位剖面上发生相位反转。利用这些特性预测胜坨油田东南角为有利的勘探地区。

关键词: 胜坨油田, 地震属性, 振幅, 瞬时频率, 瞬时相位

Abstract:

On the basis of gas reservoirs in Shengtuo oilfield being characterized by shallow reservoir distribution, simple structure and good-quality seismic data,three parameters,amplitude, instantaneous frequency and instantaneous phase have been used and integrating with drilling data to analyze the corresponding relation between these parameters and the known gas-bearing formations.The gas-bearing interval showed while drilling has a strong amplitude in the amplitude profile, a low frequency in the instantaneous frequency profile, and phase reversal in the instantaneous phase profile. By using these characteristics,the southeastern part of Shengtuo oilfield has been predicted to be a favourable gas reservoir area.

Key words: Shengtuo oilfield, seismic attribute, amplitude, instantaneous frequency, instantaneous phase
