摘要： 测井约束反演技术的最大特点是以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率的地层波阻抗资料,为储集层的精细描述提供较为可靠的依据。利用测井约束反演方法对北三台凸起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,有效提高了解释精度,并对地震反演原理、适用条件和应用效果进行了讨论。

Abstract: The great advantage of well log constraint inversion technique is in that it can effectively supplement insufficiency of limited seismic bandwidth using rich high-frequency information of well log data and complete low-frequency component,and provide more reliable basis for fine reservoir description by inversion and obtained high resolution impedance data according to given geologic information and well log data as constrain conditions. This paper offers fine description and analysis of oil-bearing sands in Beisantai Arch by means of this method, thus enriching interpretation results of seismic data, effectively improving interpretation accuracy. In addition, this paper discusses the principle of seismic inversion, suitable conditions and applicable effectiveness.

Key words: well log constrain inversion, reservoir, sand body, impedance
