张风军等.测井资料在地震控制下的迭代反演.测井技术,1997,21(3):179~184综合利用测井资料与地震资料反演岩性参数、研究储层的方法诸多且各具有优缺点,为克服其缺点,本文借助于地震岩性模拟(SLIM)的思想,提出了简单的行之有效的反演岩性及层厚的方法。即从测井数据出发,在地震资料的控制下,通过逐次迭代,精确地反演岩性及厚层参数,有效地解决了反演的多解性问题。由于迭代过程只需修改波阻抗一个参数即可反演出两个参数,提高了反演速度。
Zhang Fengjun and so on. Iterative inversion of logging data under earthquake control. Well Logging Technology, 1997,21 (3): 179 ~ 184 To comprehensively utilize logging data and seismic data to retrieve lithologic parameters, many methods of reservoir research and their respective advantages and disadvantages are presented. In order to overcome their shortcomings, (SLIM), a simple and effective inversion method of lithology and layer thickness is proposed. That is, starting from well logging data and under the control of seismic data, the inversion and multi-resolution problems are effectively solved by iteratively iterating and accurately retrieving lithology and thick layer parameters. As the iterative process only needs to modify one parameter of wave impedance, two parameters can be inverted and the inversion speed can be improved.
