地震相控非线性随机反演研究与应用

 在地震相模型控制下，通过原始数据将各个单一反演问题转化为一个联合反演问题，可降低反演在描述参数几何形态时的单个反演问题的自由度，从本质上提高地球物理反演的效果。本文在计算过程中采用了非线性随机反演算法，能有效提高地震资料的分辨率，并充分考虑地质条件的随机特性，使反演结果更符合实际地质情况。在胜利、中原油田等地区的储层预测中，应用本文方法均取得了良好的效果，为岩性油气藏勘探提供了可靠基础数据。

Study and application of seismic phase-controlled non-linear random inversion

Under the control of seismic phase model and transforming the single inversion issue into a combining inversion issue through raw data,we can improve the effects of geophysical inversions in nature.In computation,the paper used non-linear random algorithm,effectively improving the resolution of seismic data and fully considering the random character of geologic conditions,which made the inverted results more conform to practical geologic situations.In reservoir prediction in Shengli and Zhongyuan Oilfields,the application of the method achieved good results,providing reliable basic data for lithologic oil/gas reservoir prospecting.
