【摘要】:新疆北部塔城盆地南缘下二叠统卡拉岗组发育一套陆相沉积的暗色泥岩,在伯依布谢水库北侧厚达131.77m,通过采集11组样品进行有机碳含量、岩石热解、氯仿沥青"A"、族组成、镜质体反射率和干酪根镜检等有机地化测试分析,探讨其生烃潜力。结果表明,卡拉岗组暗色泥岩有机质丰度较高(TOC平均0.97%),有机质类型以Ⅲ型(腐植型)为主,热演化程度较高(Ro平均1.19%,T_(max)平均511.8℃),具有一定的生烃潜力;但其分布局限、厚度不稳定,且构造保存条件较差,综合分析认为其勘探潜力较为有限。
[Abstract]:A set of continental sedimentary dark mudstone was developed in the lower Permian Karagang formation in the southern margin of Tacheng Basin in northern Xinjiang. The thickness in the north side of Boybuxie Reservoir was 131.77 m.The organic carbon content, pyrolysis of rock and chloroform asphalt "A" were collected from 11 groups of samples. Group composition, vitrinite reflectance and kerogen microscopic analysis were used to study the potential of hydrocarbon generation. The results show that the abundance of organic matter in the dark mudstone of Karagang formation is higher (TOC mean 0.97%), the type of organic matter is mainly type 鈪,
