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。
There are many methods which use logging and seismic data comprehensively to invert lithological parameters and study reservoir. Every method has its superiority and shortcomings. In this paper, a simple and effective method is used to invert lithological parameters and bed thickness on the basis of seismic lithology modelling (SLIM). Guided by seismic data, we use logging data to invert lithological parameters and bed thickness exactly by successive iteration, hence solving the problem of multi solution in inversion. In the inversion,two parameters can be inverted only by revising the wave impedence so that inversion speed can be increased.
