摘要
讨论了叠前同步反演和模拟退火算法的基本原理,介绍了利用模拟退火算法实现叠前同步反演的技术流程,把实现叠前同步反演分为高保真地震数据处理、共角度道集生成、子波提取和同步反演四大步骤,并重点叙述了模拟退火算法在叠前同步反演中的应用。该方法在苏里格气田砂岩分布及有利含气区预测的应用结果,验证了其有效性,同时表明该方法具有运算速度快、算法稳定、预测效果好等特点。
The principle ofpre-stack simultaneous inversion and simulated annealingalgorithmis discussed.It introduced the technical process to achieve the pre-stack simultaneous inversion using simulated annealing algorithm,and departed the process into four steps:high-fidelity seismic data processing,common angle gather generation,wavelet extraction and synchronous inversion.The application of simulated annealing algorithm in pre-stack simultaneous inversion is described.This method was proved in Sulige Gas field,and the result shows the features:fast calculation,stable algorithmand good prediction effect.Forecastingresults verifythe effectiveness ofthis proposed method.
