| 摘 要： | 奥陶系鹰山组一直是塔里木盆地油气勘探的重点层位。综合运用岩心、薄片、成像测井、分析测试以及三维地震资料,对鹰山组储层特征以及影响因素进行了分析。结果表明:鹰山组整体岩性以粉-细晶白云岩,砂屑灰岩,灰质白云岩为主,储集空间以溶蚀孔洞、裂缝为主;上部为风化壳岩溶储层,溶孔-裂缝发育,中下部为裂缝性储层,裂缝发育,纵向上具有上孔下缝特征,储层非均质性强;加里东中期I幕运动形成的构造不整合面是该区岩溶储层发育的重要因素;加里东中期—早海西期形成的断裂和构造裂缝是该区储层发育的关键;早二叠世时期与火山作用伴生的岩溶烘烤以及埋藏溶蚀作用对储层发育具有积极作用。

| Abstract: | The Ordovician Yinshan Formation in Tarim basin has been regarded as the focus layer for breakthrough in oil and gas exploration.Through comprehensive use of cores,slices,logging,analytical and test data and three-dimensional seismic data,the authors analyzed the reservoir characteristics and influencing factors of Yinshan Formation.Some conclusions have been reached: the lithology of Yingshan Formation is generally composed of fine-grained dolomite,calcarenite and limy dolomite,whereas the reservoir space ... |
