【摘要】 用量化的研究思路,对碳酸盐岩储集层进行研究,主要包括求系数、定参数、算体积3个步骤。首先通过模型正演分析,明确不同宽度孔洞的地震响应特征及振幅变化规律,确定校正量版,然后利用井震结合建模的缝洞体量化描述技术,实现波阻抗体到孔隙度数据体的转化,通过孔隙空间的描述,实现缝洞单元储集空间的定量计算。更多还原

【Abstract】 The quantitative study from coefficient,parameter and volume determination includes forward modeling analysis,determination of different widths of caves’ seismic response feature and amplitude variation and correction template.Integrated with borehole-seismic model-ing description technique,the conversion of wave impedance volume into porosity data volume is made.Finally,by description of pore spaces,the quantitative estimation of reservoir space in fracture-vug unit is realized.更多还原
