不同的地震反演方法具有不同的技术特点及适用条件,针对当前石油行业常用的基于地质模型的地震反演、约束稀疏脉冲反演、储层特征属性反演、分频反演和地质统计反演等地震反演方法,从基本原理、技术关键、存在的优缺点等角度进行分析,并结合其在不同的区块、层系、储层特征和油气藏类型的应用实例,分析了各种反演方法的技术特点和适用条件。研究结果表明,针对复杂的地质目标,只有通过优选确定适用的地震反演方法,将获得的反演结果与属性分析结合,才能进一步提高储层描述的精度,达到解决复杂地质问题的目的。
Different seismic inversion methods have different technical characteristics and applicable conditions. In view of the current geologic model-based seismic inversion, constrained sparse pulse inversion, reservoir property inversion, frequency inversion and geostatistical inversion This paper analyzes the seismic inversion methods from the perspectives of the basic principle, the key technology, the advantages and disadvantages, and the application of different types of blocks, strata, reservoir characteristics and reservoir types Technical characteristics and applicable conditions of inversion method. The results show that for complex geologic targets, the accuracy of reservoir description can be further improved and the complex geological problems can be solved only by selecting suitable seismic inversion methods and combining the obtained inversion results with attribute analysis.
