当储层与非储层的声波曲线响应差异不明显时,利用常规波阻抗反演技术难以识别储层,而储层特征曲线重构技术则可提高岩性识别和储层预测的精度。讨论了如何充分利用各种测井资料进行储层特征曲线重构,来减少地震反演的多解性,并结合二连盆地ANan油田中部地区的勘探实践,总结了一套储层特征曲线重构的技术,并用其预测储层,取得了良好的效果。

The difference of acoustic wave curves between reservoir layers and non\|reservoir layers is too little to be differentiated, and it is very difficult to identify the reservoir using the inversion method of conventional impedance in some fields. In order to resolve this question, the technique of reservoir\|identifying log curve reconstruction is needed. This paper discusses how to apply various well log informations to reconstruct the characteristic curves of reservoirs to decrease the ambiguity of seismic inversion. The authors summed up a suit of techniques and means for the reconstruction of reservoir characteristic curves and used them to predict reservoirs in the middle area of the ANan oil field in the Eren basin. The effect is very remarkable.
