礁滩相油气储层预测方法研究
|
摘要
中国南方生物礁分布相当广泛,但是礁滩相储层预测一直是油气勘探的难点。本文根据地震波在含礁滩地层中的传播特性,提出利用时频分析技术和波阻抗反演技术相结合的方法进行礁滩相油气储层预测。时频分析技术在横向上能够清晰地刻画储层的分布,而波阻抗反演在纵向上具有刻画储层范围的优势,因此将两种技术相结合能够精细地刻画礁滩相储层横向和纵向的分布及油气富集的位置和范围。
There is wide distribution of biohermite in the south of China,but the prediction of coral shoal facies reservoir is always the difficulty of oil/gas exploration.Based on the propagation feature of seismic waves in coral shoal-bearing strata,the paper presented using combination of time-frequency analysis technique with wave impedance inversion technique to carry out the prediction of coral shoal facies oil/gas reservoir.The time-frequency analysis technique can clearly describe the distribution of reservoir laterally,and wave impedance inversion has superiority describing the region of reservoir vertically,the combination of these two techniques can finely describe the distribution of coral shoal facies reservoir both laterally and vertically and oil/gas concentrating position and region.
