摘　　要：弹性参数预测研究是进行隐蔽气藏勘探的重要方法。在没有多波多分量资料的状况下,基于岩石物理研究建立模型,通过利用AVO资料进行纵横波分离,然后利用分离的纵横波资料进行弹性参数反演是一种切实可行的弹性参数预测方法。研究中提出了一种利用弹性参数预测储层含气性的新方法,通过在XC气田井位论证中的实际应用,部署的探井获得了成功,证实了利用弹性参数进行隐蔽性气藏含气性预测的可靠性,具有较好的推广应用前景。The study of elastic parameters is an important means in subtle gas reservoir exploration.In the absence of multi-wave and multi-component seismic data,the adoption of rock physical modeling,the separation of P-and S-wave based on AVO data and the inversion of elastic parameters using P-and S-wave data constitute a practical and feasible method for predicating elastic parameters.This paper puts forward a new method based on μ-λ for predicting reservoir,which was used in gas well site allocation in the XC gas field,resulting in the successful deployment of exploration wells.The results confirm the reliability of the method in predication of subtle gas reservoir.This method hence has a bright future in application.
