单频成像技术在油气检测中的应用
|
摘要
单频成像技术是利用小波变换的瞬时频谱分析技术将地震信号变换到频率域,得到单频地震信息的频谱图。当储层含油气时,将会引起高频能量的衰减和低频能量的增强。通过井旁道的对比分析,确定储层由于含油气引起能量的主要高频和低频,两种频谱的对比分析更能有效地确定储层是否含油气,排除其他多解性。这可为隐蔽油气藏的研究提供有力的技术支持。
Monofrequency imaging is to transform seismic information into frequency domain to get spectrogram of monofrequency seismic information by instant frequency analysis technique based on wavelet transformation.When reservoir contains oil and gas,it will cause high frequency energy to fall and low frequency energy to rise.After ascertaining energy's major high frequency and major low frequency caused by oil and gas existence through wells analysis,it can be efficient to ascertain whether reservoir contains oil and gas or not and clear other probabilities through correlation between two frequencies,which can provide cogent technical support for research into blind reservoir.
