【摘要】：辽河坳陷结晶基底油气资源丰富,在辽河的三大凹陷基底潜山以及中央凸起均发现规模油气藏。本文通过系统分析岩芯、岩屑和旋转井壁取芯荧光、铸体和传统岩石薄片,对辽河坳陷太古宙基岩及其中的侵入体的岩石类型、含油性、储层成因及影响因素等进行了综合研究。结果表明,辽河坳陷结晶基底岩石包括2大类、14个亚类、30多种岩石类型;岩石的含油性与岩石类型、构造作用和古风化溶蚀淋滤作用的改造密切相关。在对不同岩性岩石的物理特征与测井曲线特征大量对比分析和研究基础上,建立了岩性与测井曲线的对应关系,实现了基岩岩性的测井识别,为勘探部署、储量计算等奠定了基础,也为类似基岩油气藏的勘探研究提供重要借鉴。
[Abstract]:The crystalline basement of Liaohe depression is rich in oil and gas resources, and scale reservoirs are found in the basement buried-hill and central uplift of Liaohe depression. The rock types, oil content, reservoir genesis and influencing factors of Archean bedrock and its intrusions in Liaohe depression are studied. The results show that the crystalline basement rocks in Liaohe depression include 2 types and 14 subclasses of more than 30 kinds of rocks. The petroliferous properties of rocks are closely related to the transformation of rock types, tectonics and paleo-weathering dissolution and leaching. On the basis of a great deal of comparative analysis and research on the physical and logging characteristics of different lithologic rocks, The relationship between lithology and logging curve is established, the logging recognition of bedrock lithology is realized, which lays the foundation for exploration deployment and reserves calculation, and also provides important reference for exploration research of similar bedrock reservoirs.
