摘要/Abstract

摘要： 对江苏省及近海区域地质进行了分析表明，下扬子地块发育的苏北—南黄海南部盆地为该省CO2地质封存潜在目标场所。文章通过地层及岩性资料分析了CO2封存适宜地层，在此基础上，根据钻井与地震测量剖面资料，阐述了各构造单元的800~3500 m深度范围存在的CO2封存适宜地层的厚度，探讨CO2封存空间适宜性。结果表明：盐城组下段、三垛组、戴南组、阜宁组一段与三段、赤山组砂岩具有较好CO2储存空间；苏北—南黄海盆地的赤山组分布较少，盐城组、三垛组、戴南组、阜宁组地层分布范围较广；金湖凹陷、高邮凹陷、溱潼凹陷、海安凹陷、白驹凹陷、阜宁凹陷、盐城凹陷、南二凹陷、南四凹陷、南五凹陷、南七凹陷、南二低凸起具有较好的CO2封存储层潜力；洪泽凹陷、临泽凹陷、涟南凹陷、涟北凹陷、南三凹陷、南六凹陷CO2封存储层潜力较差。

Abstract: The analysis of the geological condition in Jiangsu Province and offshore area shows that the Subei-Southern South Yellow Sea basin developed in the Lower Yangtze block is a potential site for CO₂ geological storage in Jiangsu Province. The suitable formation for CO₂ storage lithology is analyzed according to the stratigraphic and lithological data. On this basis, according to the drilling and seismic survey profile data, the suitability of CO₂ storage space is discussed through the thickness of CO₂ storage suitable stratum in 800-3500 m depth range of each tectonic unit. The results show that the sandstone layers in lower Yancheng formation, Sanduo formation, Dainan formation, the first and third members of Funing formation, and Chishan formation have good CO₂ storage space. The Chishan formation is less distributed in the basin, and the Yancheng formation, Sanduo formation, Dainan formation and Funing formation are widely distributed. Jinhu depression, Gaoyou depression, Qintong depression, Hai’an depression, Baiju depression, Funing depression, Yancheng depression, Naner depression, Nansi depression, Nanwu depression, Nanqi depression and the Naner low uplift have good CO₂ storage potential. The CO₂ storage potential of Hongze Sag, Linze Sag, Liannan Sag, Lianbei Sag, Nansan Sag and Nanliu Sag is relatively poor.
