西澳大利亚珀斯盆地页岩气资源研究Shale Gas Resource Study in Perth Basin, West Australia
杨恺,李华
摘要(Abstract)：
珀斯盆地位于澳大利亚西海岸,是西澳大利亚页岩气资源勘探的重点区域。该盆地属于复杂的凹陷裂谷,海相沉积二叠纪的Carynginia组和早三叠世Kockatea页岩层被认为是潜在的含气地层。通过搜集大量外文文献,全面总结了该盆地含气目标层的地物化特征,Carynginia组的总有机碳含量为1%~15%,干酪根为III型,Ro在0.56~1.91;Kockatea页岩层的总有机碳含量为1%~4%,干酪根为II/III混合型,Ro为0.48~1.93。两组共划分了11各岩相段,其中黑色页岩岩相段和含黄铁矿泥岩段是最重要的生烃含气层。综合考虑地层、地化指标和岩石地球物理性质,圈出了可供参考的页岩气甜点区。
