温室气体特别是二氧化碳的大量排放,是导致全球变暖的主要原因之一。根据国际能源署的报道,碳捕集利用和封存(CCUS)技术是缓解全球气候变化的重要措施之一,约占累计碳减排量的15%。原位矿化封存技术基于快速CO_(2)矿化机制,以镁铁质岩石和超镁铁质岩石(玄武岩、橄榄岩等)地层为碳封存位点,利用CO_(2)与富含Ca、Mg元素矿物的矿化反应,转变为稳定的碳酸盐,从而达到永久且高效封存CO_(2)的目的。冰岛和美国的中试项目已经证明了该技术的可行性,但中国尚未进行相关示范项目。本文介绍了原位矿化封存技术的机理、CO_(2)封存潜力的评估手段及其面临的风险与挑战,讨论了已开展的案例项目及其技术细节,梳理了实施该技术所必需的选址关键参数(包括源-汇距离、矿物类型、注入性、封闭性等),并基于目前研究对其前景进行展望,以期提高我国对原位矿化技术的认识和重视,为推动该领域进一步发展提供理论指导。

The 4th member of Shahejie Formation in Liaohe Westem Depression had experienced rapid subsidence, which resulted into massive shale with the characteristics of high organic matter abundance and sapropelic kerogen. Most shale samples have the total organic carbon （TOC） over 2%, and the value can excess 4% for dolomitic shale in Leijia area.

The research on tectonization intensity plays an important role in the analyses of basin evolution and hydrocarbon accumulation. At present, methods in this field are almost qualitative, and the quantitative one is still rarely reported. In this study, a quantitative research method for tectonization intensity is proposed. The research result on Tahe-Lunnan oilfield shows that this method can not only quantitatively express the tectonization intensity, but also qualitatively reflect the macroscopic deform property and the evolution history of strata. Therefore, it is an effective method for analyzing the characteristics of tectonization. In addition, the realization of the method also can provide qualitative information for studying the influence and control of tectonization on hydrocarbon accumulation.

虽然目前北美工业性开发的页岩气资源均在海相沉积地层中,但我国已在陆相泥页岩中获得了页岩气勘探开发的重要突破,陆相页岩气的资源潜力也正随着勘探实践的深入而被逐步揭示。为此,在研究我国陆相富有机质泥页岩分布特点的基础上,分析了主要盆地陆相富有机质泥页岩的基本地质条件和有机地球化学参数。结果认为,我国形成陆相页岩气富集具有6个方面的有利条件:累计厚度大、有机质类型多样、储集空间丰富、保存条件好、资源丰度高、地表条件好。结论指出:我国陆相富有机质泥页岩主要分布在华北及东北区、西北区及南方局部地区的中—新生界,形成陆相页岩气富集主要具有上述有利条件,而且我国陆相富有机质泥页岩发育区多与常规油气勘探开发成熟区重叠,具有资料和基础设施等方面的优势,因此具有更好的经济可采性;虽然我国陆相富有机质泥页岩具有相对较低的有机质热演化成熟度,目前多处于生油和湿气窗阶段,页岩气和页岩油在微观和宏观上呈共生伴生关系,但通过异同点对比分析后认为,我国陆相页岩气比页岩油具有更好的可采潜力。

本文从辽河西部凹陷岩心观察入手,结合岩石薄片鉴定与X衍射全岩定量分析技术,完善了湖相泥质岩类岩石学分类方法。根据新的分类方案,页岩可分为黏土型页岩、长英型页岩和混合型页岩等。其中黏土型页岩呈密集层状构造,黏土矿物为主,有机质层状富集,发育在陆源输入相对较弱的环境里;长英型页岩以泥级石英长石为主,镜下层状结构不明显,发育于陆源输入较强的淡水沉积环境;混合型页岩中发育黏土矿物、长英质和碳酸盐岩矿物,无主体成分,有机质以湖泊藻类为主,有机质纹层与黏土或者与碳酸盐岩纹层间互层结构,发育在微咸水至咸水的闭塞湖相环境。有机地化分析和生烃动力学实验研究表明半深湖相-深湖相的具有纹层结构黏土型页岩及混合型(含碳酸盐质)页岩,有机质类型以Ⅰ-Ⅱ1型为主,生烃能力很强,长英类页岩和块状泥岩次之。混合型页岩主要分布盘山洼陷沙四上亚段杜二层段和高升层段,黏土型页岩主要分布在杜家台和曙光斜坡区沙四上亚段杜一层段。混合型页岩区为油田公司近期非常规油气勘探的主攻方向。

我国南方上扬子地区广泛发育上奥陶统五峰组-下志留统龙马溪组和下寒武统牛蹄塘组2套烃源岩,为近年来的页岩气勘探事业提供了坚实的物质保障。四川盆地及周缘牛蹄塘组具有富有机质页岩厚度大、TOC丰度高、岩石脆性较好等特点,整体具备页岩气发育的有利条件,但其含气性明显不及上部的五峰组-龙马溪组。从渝东南地区YY1井牛蹄塘组的极低电阻率测井响应入手,基于干岩样岩电实验、全岩X射线衍射定量分析等测试成果的分析初步认为:在测井曲线和岩电数据中出现的极低电阻率值是由高演化有机质中的高导矿物——石墨引起;石墨为生烃进入高温生气阶段的标志性产物之一,预示着有机质炭化程度达到区域高值。另外,通过对比牛蹄塘组和五峰组-龙马溪组的电性参数、地球化学数据与测井曲线可知,YY1井牛蹄塘组富有机质泥页岩层已发生石墨化,其生气能力、基质孔隙发育等方面均不及上部五峰组-龙马溪组,属于研究区页岩气勘探相对不利层位;此外,电阻率测井可作为页岩气勘探前期预判的重要指标之一,极低电阻率可指示对应层位有机质演化成熟度过高,含气性和生烃能力欠佳,不利于后期页岩气的勘探开发。
