摘　　要：吉木萨尔凹陷芦草沟组致密油储层岩性多变,矿物成分多样,且多为碎屑岩和碳酸盐岩的过渡性岩类。复杂的岩性条件给岩石分析样品的准确定名和测井岩性识别带来了较大的困难。通过岩心观察、薄片鉴定、全岩X射线、全岩氧化物分析等多种资料相互印证,实现了岩矿分析样品的准确定名;高分析密度的注氦孔隙度测量和高分辨率的核磁共振测井相结合、岩心扫描图像和微电阻率扫描图像相结合,实现了厘米级的岩心归位精度,搭建了岩、电关系的桥梁;核磁共振测井和常规测井相结合,构建了2个岩性敏感参数,建立了具有适应性的岩性识别图版,较好地解决了测井岩性识别的技术难题。Abstract： The lithology and mineral composition of the tight oil reservoir in Lucaogou tormatlon of Jimusaer depression are complex and diverse,and maiority of them are transition rock between clastic rock and carbonate rock. It is difficult to name for the rock section sample exactly and identify by logs in this case. With combined measurements and verification of thin section analysis, total bulk X-ray and total bulk oxide data, we can name section sample exactly; Combined the section sample helium injection porosity measured data with NMR high-resolution porosity data and combined the scanning images of rock core with micro resistivity images, we got centimeter-sized accuracy of the core location,then, built a bridge between lithology and logging data; Combined NMR log data and conventional log data, we built two lithology sensitive parameters, the adaptability of lithology identification chart was established, which better solves the problems in logging lithology identification.
