摘要
为判明黄骅坳陷千米桥奥陶系潜山天然气藏的气源问题 ,对大港地区不同层位烃源岩进行热模拟实验。采用气源综合动态对比思路 ,根据对模拟得到的产气率、轻烃、轻烃碳同位素的研究 ,对千米桥奥陶系潜山天然气进行动态气源对比。对比结论 :板桥凹陷和歧口凹陷沙三段烃源岩均可为千米桥奥陶系潜山供气 ,认为潜山凝析油主要来源于烃源岩成熟阶段 ,天然气主要来源于烃源岩高成熟阶段。图 6表 2参 4(罗霞摘 )
The natural gas pool of Ordovician buried hill in Qianmiqiao in Huanghua depression is a great discovery. The comprehensive dynamic correlation methods of natural gases with their source rocks are applied in this article, such as different stratohorizion thermal simulation production of and thermal simulation gasoline hydrocarbon and thermal simulation carbon isotope ratio of Toluene, C 1, C 2, C 3, C 4 of rock, combining gasoline hydrocarbon and carbon isotope ratio of Toluene, C 1, C 2, C 3, C 4 of natural gases. The correlating conclusions are:(1) The natural gas pool of Ordovician buried hills in Qianmiqiao in Huanghua depression mainly came from Tertiary system which is at high maturity stage. (2) The condensate oil of Ordovician buried hill also came from Tertiary system, which is at mature stage.
