摘　　要：由于页岩油非常规油藏特殊的地质特征,常规测井曲线无法对页岩油储集层的含油性和物性进行有效评价,必须依赖核磁测井进行相关评价,而应用核磁测井进行储集层评价费用昂贵,不便于大规模应用。以准噶尔盆地吉木萨尔凹陷芦草沟组页岩油为例,通过深入挖掘录井资料的潜力,发现录井参数与核磁孔隙度相关性较好,进而以核磁测井为参考标准,利用录井参数进行储集层孔隙度的拟合计算,形成了基于录井资料的储集层评价技术。运用该技术指导页岩油储集层压裂改造取得了良好的效果。Because of the special geologic characteristics of unconventional shale oil reservoir,conventional well log can not evaluate the oil bearing and physical properties of shale oil reservoir effectively,and it is necessary to rely on nuclear magnetic logging for relevant evaluation.However,the reservoir evaluation by nuclear magnetic logging is expensive,which is not suitable for large-scale application.Taking the shale oil of Lucaogou Formation in Jimsar sag in the Junggar Basin as an example,it is found that the correlation between mud logging parameters and nuclear magnetic porosity is good by deeply tapping the potential of mud logging data.Then taking nuclear magnetic logging as the reference standard,the reservoir porosity is fitted by mud logging parameters,and the reservoir evaluation technology based on mud logging data is formed.Good results have been achieved by using this technology to guide shale oil reservoir fracturing.
