| 摘 要： | 昆北断阶带基岩油藏的发现是柴达木盆地西南地区油气勘探的一个重大突破。在录井资料、岩心观察、薄片鉴定及成像测井资料分析的基础上，研究了昆北断阶带基岩油藏的岩性和储集空间类型及其影响因素。结果表明，基岩储层岩性主要为花岗岩和板岩，储集空间可分为构造缝、溶蚀缝和溶蚀孔三大类，储集层类型为裂缝-溶蚀型。基岩薄片和物性分析数据表明基岩储集空间复杂，渗透率低，沿裂缝发育的溶蚀孔隙物性较好。最后分析认为影响储集空间发育的因素主要有基岩岩性、构造运动、成岩作用等。

| Abstract: | The discovery of basement reservoir in Kunbei fault terrace belt is an important exploring breakthrough in southwestern Qaidam Basin. Based on the analysis of well logging data, core observation, section identification and imaging well logging data, the lithology, reservoir space and influencing factors of basement reservoir in Kunbei fault terrace belt are expounded. The result shows that the lithologies are mainly granite and slate, the reservoir spaces contain tectonic fissure, dissolved fissure and diss... |
