鄂尔多斯盆地志丹油田永宁地区长6油藏类型及成藏模式探讨

借助大量钻测井、岩心录井、试油试采等资料，并结合多种测试方法及分析手段，深入地、系统地研究了该区地层、构造、储层沉积微相类型及展布特征、储层特征等基础上，进一步对长6油气藏进行全面综合剖析，指出长6油气藏类型主要为：①砂岩上倾尖灭岩性油气藏；②砂岩透镜体岩性油气藏；③非均质性遮挡岩性油气藏；④构造—岩性复合油气藏。在综上研究基础上，最终总结及建立了长6油气成藏模式。

Research on the type of Oil &gas reservoir and the mode of reservoir-formed on Chang-6 oil reservoir in yongjing area of the southern of zhidan oil field,ordos basin

with a large number of logging ,drilling, core logging, test oil such as test--mining information, combined with a variety of testing methods and analysis tools , thoroughly and systematically studied on the area stratigraphy, tectonics, sedimentary microfacies types and distribution characteristics, reservoir characteristics,etc. But also for the Chang 6 oil ＆ gas reservoirs for a comprehensive and integrated analysis, pointed out that the major types of Chang- 6 oil ＆ gas reservoirs are as follows. ① Up-- lip pinch--out sandstone lithology reservoir; ② Sandstone lenticular--body lithology reservoir; ③Barrier heterogeneity lithologic reservoir ;④Structure -- lithology composite reservoir. Based on comprehensive study , the final ,summed up and established the Chang 6 oil ＆ gas reservoir--formed mode.
