We report a simple strategy to construct a multiple gadolinium complex decorated fullerene (CGDn) as an enhanced T1 contrast agent.The CGDn exhibits much higher T1 relaxivity (-49.7mM-1s-1) than individual Gd-DOTA,and shows excellent T1 contrast enhancement ability both in vitro and in vivo.

核磁共振(NMR)测井在沉积岩储层识别、孔隙度、渗透率计算及流体识别等方面发挥着其他测井不可替代的作用.近些年,国内外相继发现以火成岩为主的大型油气藏,火成岩岩性、岩相、储集空间、孔隙结构、矿物成分、元素组成等复杂多样,该类储层核磁共振测井解释与评价的精度不高,其应用受到了很大限制.为此,开展火成岩核磁共振影响因素分析与解释方法研究不仅具有重要的理论研究意义,也具有迫切的实际应用价值.本文以火成岩

致密砂岩气储层基质渗透率一般小于0.1mD,孔隙度<10%,单井一般无自然产能或自然产能低于工业气流下限,裂缝对提高致密砂岩储层渗流能力起到主导作用.研究利用核磁共振表征致密砂岩裂缝,联合多种常规实验方法,明确裂缝厚度对核磁共振信号、储层渗透率的影响.石盒子组致密砂岩以岩屑砂岩为主,次为岩屑石英砂岩,为了进一步研究,现按基质、裂缝、渗透率级别分别进行相关性研究。实验结果说明:通过裂缝模型测试核磁共
