| 摘 要： | 测井约束波阻抗反演技术的最大特点是利用测井资料丰富的高频信息和完整的低频成分补充地震有限带宽的不足,用已知地质信息和测井资料作为约束条件,通过反演得到高分辨的地层波阻抗资料,为储集层的精细描述提供较为可靠的依据。利用多井约束反演方法对四2区含油砂体进行了精细描述和研究,丰富了地震资料的解释成果,从整体上提高解释精度,解决了薄互储层识别难的问题,并对地震反演原理、应用效果进行了讨论。

| Abstract: | The most prominent characteristics of logging constrained wave impedance inversion technology are to offset the limited seismic bandwidth by using the abundant high frequency information and complete low frequency component. Taking available geologic information and logging data as constraints, this technology can achieve high resolution wave impedance data through inversion, which provide a reliable foundation for fine characterization of reservoir. Multiwell constrained inversion technology is used to finely describe and study the oil-bearing sandbodies in Si2 block. Seismic interpretation results are enriched, the overall interpretation accuracy is improved, interbeded thin reservoirs are successfully identified. Seismic inversion theory and its application effects are also discussed in this paper. |
