【摘要】：为进一步明确鄂尔多斯盆地黄陵地区长6油层组油气成藏条件,利用钻井、测井、录井、试油资料、薄片观察以及分析化验等资料,通过对研究区烃源岩、储集层、盖组合及圈闭特征的研究,分析油气成藏主控因素。研究表明,长6油层烃源岩为下部长7湖相暗色泥岩,同时储层物性较好,具备有效的生储盖组合,较好的油气成藏条件。认为长6油气成藏的主要控制因素为近油源、优势相和较低的剩余孔隙压力。对确定黄陵地区油气聚集的有利区域,指明下一步勘探部署方向和范围具有重要的指导意义。
[Abstract]:In order to further clarify the oil and gas accumulation conditions of Chang 6 formation in Huangling area, Ordos Basin, by using drilling, logging, logging, oil testing data, thin slice observation and analysis and laboratory analysis, the source rocks in the study area were analyzed. The study of reservoir, cap assemblage and trap characteristics, and analysis of the main oil and gas reservoir forming control factors. The study shows that the source rock of Chang 6 reservoir is lower 7 lacustrine dark mudstone, and the reservoir physical property is better. It is considered that the main controlling factor of Chang 6 oil and gas accumulation is near oil source. The dominant facies and lower residual pore pressure are of great significance in determining the favorable area of oil and gas accumulation in Huangling area and pointing out the direction and scope of exploration and deployment in the next step.
