摘要
对叠后地震剖面进行构造解释后，再从井旁道出发对目标层段进行非等时的外推波阻抗反演，使用相同层位的地震数据能够在相同低频背景的约束条件下进行反演运算。这对于提高解的精度、减少反演的多解性是十分有益的。本文描述了测井和构造形态共同约束下的地震资料目标反演方法。该方法综合了测井约束反演和模型法反演的优点，避免了它们各自的缺点。实际资料的反演结果表明，该方法具有较高的分辨率和运算速度，及演出的地震参数具有较高的可信度和明确的地质意义，可用于油气勘探开发中的储层或油藏预测。
After the structural interpretation of post-stack seismic section, non-isotime extrapolated wave impedance inversion of target horizon is made, starting from borehole-side trace, to achieve seismic inversion operation of the same horizon under a restriction of equal low frequency background. This benefits accuracy improvement and multi-solution reduction in inversion.Commended here is a method for target inversion of seismic data under restrictions of logging and structural data. This method has the advantages of loggingrestricted inversion method and modeling method, but avoids their disadvantages. It is testified practically that this method brings good resolution and fast operation,and produces reliable seismic parameters which have definite geological meaning. It is used to predict reservoirs in hydrocarbon exploration and development.
