摘　　要：STRATA和JASON是储层预测的两种主要反演技术 ,它们的初始模型是根据测井资料建立的。高角度裂缝基本无测井响应 ,因此基于这种模型的反演精度将受到影响。在AIMS技术中 ,初始模型主要是建立在波形特征之上的 ,故高陡裂缝有良好的地震响应。但该技术的缺陷是不能全面反映整个工区的情况。在对以碳酸盐岩裂缝为主要储集层的塔里木T油田奥陶系油层进行储层预测的过程中 ,尝试将AIMS技术与STRATA和JA SON进行有机的结合以提高预测的精度。实践表明 ,效果十分理想。STRATA and JASON are two inversion methods that are most commonly used in reservoir prediction.Their original models are constructed from logging data.Because steep fractures have almost no logging responses,inversion methods that are based on such models have great limitation.The original model of AIMS technique is based on characteristics of seismic wavefrom,steep fractures on such model can yield good seismic effect.However,AIMS is unable to describe the whole work area.The main reservoirs of T oilfield,Tarim Basin are fractured carbonate rocks.AIMS was used in combination with STRATA and JASON to predict the Ordovician reservoir of the T oilfield.Satisfactory results have been yielded by the application of this method to real data.
