| 摘 要： | 地震叠前弹性参数反演可以为解释人员提供丰富的岩性和流体的信息。针对上述典型的非线性反演问题,模拟退火法在解空间进行全局寻优,克服了线性算法容易陷入局部极值的缺陷,但其计算速率较低。为此,本文首先详细地介绍了一种快速模拟退火算法,并将其应用到叠前三参数同步反演,主要是采用似Cauchy分布产生初始模型,广义Gibbs分布作为接受准则,并对由叠前数据求得的目标函数快速搜索全局最优解。通过模型试验表明,基于本文的快速模拟退火算法反演得到的三参数不仅精度高,而且计算效率得到了一定的提高。

| Abstract: | The pre-stack elastic parameter inversion,which is a nonlinear inversion method,provides rich information of lithology and fluid for interpreters.Simulated annealing can be used in this method to locate the global optimum in a solution space,however,it is time-consuming.A fast simulated annealing algorithm is introduced in this paper,which uses Cauchy distribution to generate initial models and obtains the acceptance probabilities from the generalized Gibbs distribution.The model test indicates that the pre-stack simultaneous inversion based on this fast simulated annealing algorithm can produce accurate three-parameter and improve the calculating efficiency. |
