摘要(Abstract)：

大长沟盆地石碳窑北下侏罗统八道湾组油页岩含矿区位于新疆巴里坤县长虫梁地区,是我国目前正在开发的优质油页岩矿床。本次在岩心观察和测试分析的基础上,运用测井模型开展油页岩评价,为本区油页岩资源评价提供依据。研究表明油页岩TOC与密度、电阻率和自然伽马测井曲线存在线性相关,通过测井曲线预测TOC,进而根据TOC与含油率的线性关系,计算含油率;本次优选ZK1601钻井密度测井曲线(R~2=0.47)与电阻率测井曲线(R~2=0.35),建立ΔLogR模型,通过对ΔLogR公式进行改进,进行ZK1601钻井的TOC值预测,预测TOC与实测的TOC线性相关性好,将该ΔLogR模型在ZK0010井进行验证,计算出的TOC与实测的TOC线性相关性良好(R~2=0.72),据此可对该区其他井开展预测,获得油页岩含油率、TOC、厚度、埋深等相关参数。

关键词(KeyWords)： 油页岩;ΔLogR;有机碳;含油率;大长沟盆地;新疆
