| 摘 要： | 河南舞阳、襄城凹陷下第三系核桃园组为一套含膏岩、盐岩的暗色泥岩生油建造 ,大部分暗色泥岩属较好和好的烃源岩 ,生油母质以Ⅱ1型为主 ,烃源岩大部分处于未熟—低熟演化阶段。两凹陷在已钻探的井中见到丰富的油气显示 ,并试获少量原油 ,均属未熟—低熟油 ,但是至今未发现工业油流。通过与江汉盆地的对比研究 ,认为舞阳、襄城两凹陷具备形成中小油气田的地质条件 ,有望获得工业油流。

| Abstract: | The Paleogene Hetaoyuan Formation is mainly a set of salt-bearing and gypsiferous dark mudstone in Wuyang and Xiangcheng sags.Most of the mudstones are good source rocks and thermally immature or less matured(R o=0 3%～0 7%).Kerogen types are mostly type Ⅱ.Twenty wells have been drilled,and evidences of oil and gas are found in 11 wells,but only a little crude oil is produced through well-testing.It is estimated that the total oil resource is about 1×10 8 t and 60 percent of that is immature oils(0 6×10 8 t).Comparing with the similar oil-bearing basin,the Jianghan Basin,it is shown that Wuyang and Xiangcheng sags have the geological conditions of forming hydrocarbon accumulation,and are expected to find small or medium commercial oil pools. |
