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。

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.
