| 摘 要： | 南阳凹陷为典型的陆相断陷盆地,凹陷南部边界断裂附近区块成为油气勘探的潜力目标区。利用岩心、钻井、地震等资料,综合运用构造古地貌、地质和地球物理等方法,通过对南阳凹陷南部边界断裂附近的沉积相进行精细的分析和研究,指出核桃园组第2段第3亚段(E3h2-3)发育的沉积相类型包括北部的辫状河三角洲前缘、南部边界断裂附近的扇三角洲和湖中心的浊积相。凹陷内的储层含油性与其物性关系密切,扇三角洲和辫状河三角洲前缘具有很好的成藏条件。进一步研究表明,通过对凹陷南部边界断裂附近的小型扇三角洲的精细研究和刻画,可以为后期勘探突破提供目标和方向。 |

| Abstract: | The Nanyang depression is a typical continental rifted basin with a boundary fault in the south and strata overlapping in the north.The area near the south boundary fault becomes the potential target of petroleum exploration.By utilizing the structural paleogeomorphology,geology and geophysics and combined with rock cores,well logging and seismic data,three major sedimentary facies can be recognized,that is,the braided-river fan delta front,fan delta,lacustrine and turbidite in the Member 2 of Paleogene Hetaoyuan Formation(E3h2).The oil saturation of the reservoir is related with its property.The pool-forming conditions in Fan delta and braided-river delta front are favorable.Further studies show that the small-size fan delta can provide a target area for the late petroleum exploration by the scrutiny in the area near the south boundary fault. |
