On the basis of sorting out current understanding of solid bitumen (SB) in shales and taking organic-rich shales in the first member of the Cretaceous Qingshankou Formation in the Songliao Basin as an example, the definition, classification, occurrence and evolution path of SB are systemtically studied, and the indicative significance of SB reflectance (Rob) on maturity and its influence on the development of reservoir space are discussed and summarized. The results show that the difference of primary maceral types is primarily responsible for the different evolution paths of SB. Most of the pre-oil bitumen is in-situ SB with only a small amount being of migrated SB, while most of the post-oil bitumen and pyrobitumen are migrated SB. From the immature to early oil maturity stage, bituminite, vitrinite, and inertinite can be distinguished from SB based on their optical characteristics under reflected light, and alginite can be differentiated from SB by their fluorescence characteristics. Under scanning electron microscope, in-situ SB and migrated SB can be effectively identified. Rob increases linearly with increasing vitrinite reflectance (Ro), as a result of a decrease of aliphatic structure and the enhancement of aromatization of SB. Within the oil window three types of secondary pores may develop in SB, including modified mineral pores, devolatilization cracks and bubble holes. At a high maturity stage spongy pores may develop in pyrobitumen. Scanning electron microscopy combined with in-situ SEM-Raman spectroscopy can further reveal the structral information of different types of SB, thus providing crucial data for understanding for understanding OM migration paths, dynamics, and distances at micro-scale.

页岩中已被证明含有大量可供开采的油气资源,厘清页岩中异相流体含量及赋存态对页岩油的开发至关重要。二维核磁共振技术能够对页岩中含氕(1H)化合物进行无损、快速、定量检测。对松辽盆地青山口组一段页岩样品进行抽提前后、自发渗吸以及加热过程中的核磁共振检测,定量评价青一段页岩异相流体含量、赋存状态以及页岩放置时的流体散失。结果表明,在核磁二维谱图上,类固体有机质和轻质烃类主要分布于T1大于10 ms的上方区域,两者间基本以T2=0.1 ms为界,分别与有机碳含量TOC及S1(游离烃)具有良好的线性关系。松辽盆地南部青一段页岩油主要以游离及吸附态赋存,页岩粘土含量越高,吸附态页岩油含量越高,游离态越少。页岩自发渗吸过程中的核磁共振检测结果表明了粘土矿物吸水膨胀作用。在页岩抽真空加热过程中,轻质烃挥发损失的同时水也大量地损失。利用密闭取心样品,结合二维核磁共振技术,可恢复其原始含油饱和度和含水饱和度。

截止目前古龙凹陷页岩油的开发已见成效,总结古龙页岩油富集的地质条件对下一步的勘探开发工作尤为重要.对当前古龙页岩油基础地质特征及勘探成果进行了梳理总结,归纳了规模见产可能面临的科学技术问题,并探讨了下一步科研攻关方向.松辽盆地北部青山口组一段页岩具有机质丰度高(TOC为2.0%~3.0%,平均2.7%)、类型好(以I型干酪根为主,生烃母质为层状藻类体)、成熟度高(Ro为1.20%~1.67%)、黏土矿物含量高(大于35%)等典型特征.受益于较高的地温梯度,古龙凹陷青一段有机质达到高成熟阶段,油质轻(地面密度小于0.8 g/cm^(3))、气油比高(大于50 m^(3)/m^(3)),具备高熟页岩油规模开发潜力.页岩油甜点评价标准的厘定、单井EUR预测存在不确定性及规模效益开发配套技术欠缺是古龙页岩油勘探开发目前面临的主要挑战.黏土矿物对油水赋存状态乃至含油饱和度的影响、复合润湿性对压裂液渗吸置换效率的控制等陆相页岩油特有机理研究的突破,将会推动国家级开发示范区产油目标的快速实现,并有望在轻质油带开发基础上向稀油带扩大古龙页岩油勘探开发成果.

在梳理国内外页岩固体沥青研究现状的基础上,以松辽盆地白垩系青山口组一段富有机质页岩为例,对固体沥青的定义、分类、赋存形式和演化路径进行深入研究,探讨固体沥青对成熟度的指示意义及其对储集空间发育的影响。研究表明:①原生显微组分类型差异是造成固体沥青演化路径不同的主要原因,油前沥青多为原位固体沥青,而油后沥青和焦沥青则多为迁移固体沥青;②在未成熟—生油阶段早期,沥青质体、镜质体、惰质体可通过光学特性观察与固体沥青进行区分,藻类体可通过荧光特征与固体沥青进行区分;③扫描电镜下可有效识别原位和迁移固体沥青,受脂族结构减少、芳构化增强的影响,固体沥青反射率随着镜质体反射率的增加而呈线性增加;④生油窗内的固体沥青主要发育残留孔、脱气裂缝和气泡孔3种次生孔隙类型,高成熟阶段的焦沥青发育海绵状孔隙;⑤扫描电镜结合激光拉曼光谱等原位分析技术的应用,可以反映不同类型固体沥青的结构信息,用于有机质迁移路径、动力等微尺度研究。

主动介入和被动介入是智库介入政策过程的两类方式,相对于直接介入与间接介入,或者自下而上介入与自上而下介入,这种分类方式更加具有实质意义。不论是在议程设置阶段还是在方案设计阶段,智库的主动介入都抓住了有利的介入时机,能够有效影响政策制定者咨询需求的形成和满足;智库的被动介入则错失了有利的介入时机,无力影响政策制定者咨询需求的形成和满足。对主动介入和被动介入两种介入方式进行比较分析,可以为新型智库建设和智库影响力提升提供有益启示。

公钥可搜索加密能实现基于密文的信息检索,适用于云计算环境。但现有公钥可搜索加密方案普遍依赖于双线性对,并且无法对服务器返回的搜索结果进行验证,效率和安全性较低。为此,基于El Gamal加密算法提出一种可验证的公钥可搜索加密方案。该方案使用El Gamal加密算法替代双线性对运算,与传统算法相比具有较低的计算复杂度,并且易于实现。在密文关键词及加密文件生成算法中,采用El Gamal签名算法对关键词的哈希值进行数字签名。当收到服务器返回的搜索结果后,用户可以通过计算得到发送者的公钥,并对相应的签名值进行验证,从而有效防止服务器返回错误结果。
