常用叠后波阻抗反演技术评析

根据反演软件的基本原理及实现方式,对叠后地震波阻抗反演方法进行了分类研究。结合实际处理经验,总结出道积分、递归反演、广义线性反演、稀疏脉冲反演、ISIS模拟退火反演、随机模拟、随机反演和特征反演等方法的各自特点和应用的局限性,以及不同反演方法在测井与地震资料上所起的作用。以济阳坳陷为例阐述了不同地质条件下,以储层预测为目的的反演对策。

Evaluation and analysis on the post-stack wave impedance inversion technique in common use

The post -stack seismic wave impedance inversion methods are classified based on the fundamentals and realization ways of the inversion software. The advantage, the applicable limit and the effect of different inversion methods on log and seismic data are summed up combined the practice experience, these methods include the trace integration, recursive inversion, generalized linear inversion, sparse spike inversion, ISIS simulated annealing inversion, stochastic simulation, stochastic inversion and characteristic inversion etc. The inversion strategy aiming at reservoir prediction under the various geological setting of Jiyang Depression is pointed out in this paper.
