| 摘 要： | 在突泉盆地南部突D2井的钻探过程中发现厚层暗色泥岩中产Klausipollenites schaubergeri等19属26种具浓厚晚二叠世时代特征的孢粉化石.生物地层及岩石地层显示，这套暗色泥岩为上二叠统林西组，其单层厚度及总厚度大.本文从有机质丰度、类型、成熟度等方面分析了突D2井暗色泥岩的生烃潜力.有机质丰度为中等-好.有机质类型为Ⅱ1型.有机质成熟度为过成熟.显示突泉盆地林西组暗色泥岩具有良好的页岩气勘探前景.

| Abstract: | A suit of thick grayish-black mudstone is intersected in the TD2 well in the southern boundary of Tuquan Basin.Spores and pollen fossils of 26 species in 19 genera,including Klausipollenites schaubergeri et al.,which indicate an age of Late Permian,are found in the mudstone.Comparison of biostratigraphy and lithostratigraphy confirms that the strata belong to Upper Permian Linxi Formation.Analysis on the abundance,type and maturity of organic matter shows a great hydrocarbon-generating potential of the dark mudstone from TD2.The organic matter abundance is medium-good,belonging to Type Ⅱ,in overmature stage.This result suggests that the source rock of Linxi Formation in Tuquan Basin is promising for shale gas. |
