中文摘要： 致密砂岩油气以其巨大的资源潜力可观的规模储量日益引起广泛关注。复杂成岩作用造就了其岩性致密、物性差、孔隙结构复杂且非均质性强的特征。在特定的沉积相背景下，成岩相决定了致密砂岩储层甜点的形成与分布。课题立足于砂岩储层成岩相分类方案不统一、且缺乏完善的测井定量表征方法等问题。以不同盆地典型致密砂岩储层为例，在其成岩作用类型、强度及成岩矿物组合特征研究的基础上探讨成岩相系统的分类方案及识别评价参数，然后通过岩心薄片等分析化验资料刻度测井，归纳总结不同成岩相在常规测井曲线上的响应特征，建立不同成岩相的测井识别模式与准则，并结合ECS等测井新技术对成岩相识别结果进行标定，由此将成岩相的研究由点向线和面上拓展，并通过成岩相分布规律对储层甜点进行预测。课题预计将在致密砂岩储层成岩相分类体系、定量表征参数及其测井识别方法方面取得创新性成果，发表SCI论文3-4篇，申报专利和软件著作权各一项。

英文摘要： The tight sandstone reservoir as a type of widely distributed reservoir with great hydrocarbon potential, has aroused extensive attention. Complex diagenesis leads to its dense lithology, poor physical property, complicated pore structure and strong anisotropy. Under the condition of certain sedimentary facies, diagenesis facies determines the formation and distribution of sweet spot of tight sandstone reservoir. This project is based on the basic issues of uniform classifications and nomenclature of clastic reservoir diagenetic facies and lack of thorough well-logging method of quantitative characterization, etc. Taking typical tight sandstone reservoirs of different basins as examples, based on diagenesis types, intensity and characteristics of diagenesis minerals, the classification, nomenclature and evaluation parameters of diagenesis are discussed. Through testing data including core and thin sections to calibrate logging, well logging response features of different diagenetic facies can be summarised and then, logging recognition standard of diagenetic facies can be established. Combined with well-logging new technology, eg. natural Gamma Ray Spectrometry log , ECS etc. to calibrate the results of recognition of diagenetic facies, in order to extend the study of diagenetic facies from point to line and plane. The sweet spot can be predicted by the distribution of diagenetic facies. This project is expected to made innovative achievements in the aspects of diagenetic facies classification and nomenclature of tight sandstone reservoir, quantitative characterization parameters and well logging recognition methods. 3-4 SCI papers are expected to be published. 1 patents and 1 software copyright are planned to apply.
