摘　　要：将系统工程领域的层次分析法(AHP)应用于地震储层预测中。按照层次分析法递阶层次原理,结合春风油田P609井区实际地质情况,在波阻抗反演、地震多属性分析和断层裂缝预测等基础上,确定出储层预测四级层次结构,即基础数据层、方案层、准则层和目的层。实际应用中,研究区16口井中有14口井的AHP预测结果与录井结果一致,应用效果较好。该方法将有利储层预测这一较复杂的问题分解为若干个次级物理意义和地质意义较明确的问题,从而达到了更好、更全面分析储层的目的。该研究方法对研究区后续开发有指导意义,对国内其他类似区块有借鉴作用。The analytic hierarchy process( AHP) of systematic engineering field was applied in seismic reservoir prediction in this paper. Based on hierarchical principle of analytic hierarchy process( AHP),combined with actual geologic conditions of wellblock P609 in the Chunfeng Oilfield,on the basis of wave impedance inversion,seismic multiattribute analysis and fault fissure prediction,four- level hierarchical structure was confirmed,i. e.,basic data layer,plan layer,criterion layer and target layer. In practical application,the AHP prediction results of 14 wells( 16 wells in the study area) were consistent with the mud logging results,showing a good application effect. This process broke the favorable reservoir prediction( a rather complicated problem) into severalsecondary problems with relatively definite physical significance and geological significance,and thus achieved the objective of better and more complete analyzing the reservoirs. This study approach has guiding significance to the subsequent development of the study area,and can be used for reference in other similar blocks in China.
