摘要
用地震资料进行储层描述,首先要求地震数据具有较高的信噪比和分辨率。反Q滤波能去掉时变的吸收作用影响,用极大似然反褶积则能最大限度地压缩子波。以高分辨率地震资料为基础,进行地震速度反演,获得较好的速度剖面。用速度剖面结合井中资料,估算孔隙度、净毛比等油藏参数,最后估算出石油地质储量。已编制出“储层地球物理软件(RGS)”并在实际中应用。
To conduct reservoir description using seismic data requires high resolution and high signal to noise ratio of seismic data.The inverse Q filtering can remove the effects of absorption.The maximum likelihood deconvolution can compress the basic wavelet to the maximum.To conduct the seismic velocity inversion based on the high resolution seismic data results in the better seismic velocity profile.Combining the well data with seismic velocity profile estimate the reservoir parameters such as porosity,net/gross ratio,…etc.Finally calculate in place hydrocarbons.A software package was developed,named Reservoir Geophysical Software(RGS),and it was used in real data.
