摘　　要：以二连盆地阿尔凹陷凝灰质砂岩储层为研究对象,在分析该区岩心试验资料、地质资料、测井资料及其响应特征的基础上,进一步研究了利用测井曲线计算凝灰质含量的有效方法,进而建立了基于凝灰质含量的物性参数计算模型。实际应用表明,模型计算结果与试油结论符合度较高,提升了阿尔凹陷的储层综合评价水平。By taking tuffaceous sandstone reservoir in A'er Sag of Erlian Basin as a subject of study,and on the basis of analyzing core testing,geologic and well logging data and as well as logging response characteristics,an effective method for calculating tuffaceous content by using logging curves was further studied.A model for calculating physical parameters based on tuffaceous content was established.Application shows that the model calculation results are consistent with that of oil testing,by which the level of comprehensive reservoir evaluation is improved in A'er Sag of Erlian Basin.
