摘要
根据胜坨油田气藏分布浅 (1 5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。
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.
