Abstract

Reservoirs of Dalan and Kangan have recently attracted considerable interest due to their enormous energy extraction potential. However, key technical information such as composition and pore characteristics have been unavailable. This investigation conducts a comprehensive analysis of the Dalan and Kangan shale reservoirs' properties. X-ray diffraction confirmed the presence of calcite, lime, quartz, kaolinite, hematite, titania, and alumina compounds in the specimens. Electron spin resonance analysis confirmed that the reservoirs possessed paramagnetic substances. Fourier transform infrared analysis confirmed the presence of organic matter and other carbonite compounds in the reservoirs. Thermogravimetric analysis indicates that approximately 44 % of the reservoir sample consists of carbonate species, encompassing organic materials and other chemicals. The microstructure of Dalan and Kangan reservoir was also studied using a field emission scanning electron microscope and a high-resolution transmission electron microscope, demonstrating a network of microfractures, macropores, mesopores, and micropores interconnected within the clay matrix.

大兰和康干储层结构研究：聚焦离子束扫描电子和透射电子显微镜表征

大兰和坎干水库由于其巨大的能源开采潜力，最近引起了相当大的兴趣。然而，诸如成分和孔隙特征等关键技术信息一直无法获得。综合分析了大兰组和康干组页岩储层的物性特征。x射线衍射证实了样品中方解石、石灰、石英、高岭石、赤铁矿、二氧化钛和氧化铝化合物的存在。电子自旋共振分析证实储层具有顺磁性物质。傅里叶变换红外分析证实储层中存在有机质和其他碳酸盐化合物。热重分析表明，约44. %的储层样品由碳酸盐组成，包括有机物质和其他化学物质。利用场发射扫描电子显微镜和高分辨率透射电子显微镜对大兰和康干储层的微观结构进行了研究，发现粘土基质中存在微裂缝、大孔、中孔和微孔相互连接的网络。
