地震道的分形维计算及在滩海地区油藏描述中的应用
|
摘要
研究在滩海地区实现少打井多探明油气储量。首先给出利用地震数据求取容量维(振幅维)、关联维和R/S分析分形维等3种分形维数的计算方法,并阐明它们各自的物理意义。在分析滩海地区地震和地质条件的基础上,通过制作地质模型和对实际地震资料的分形维数计算,探讨了应用地震道的分形维数进行储层预测和油气检测的方法。在胜利滩海地区的应用实践表明,分形分维技术能够较准确地反映由地震波形等引起储层和油气层的变化,是1种比较好的进行储层预测和油气检测方法,在滩海地区的油藏描述中发挥了重要作用。
Three methods were introduced to acquire the capacity dimension(amplitude dimension),associated dimension,fractal dimension in R/S analysis by using the seismic data,and their physical significances were elucidated,so that more oil and gas reserves could be discovered with fewer wells drilled in the coastal region.On the basis of analyzing the seismic and geologic condition in the coastal region,by means of designing the geological model and fractal dimension calculation of the actual seismic dimension of seismic traces the method for reservoir prediction and hydrocarbon detection was discussed.The application in the coastal region indicated that fractal dimension technology can explain the change of seismic wave shape as the hydrocarbon reservoir itself.So the reservoir prediction and hydrocarbon detection methods by using the fractal have important applications in coastal regions.
