| 摘 要： | 乌尔逊凹陷是海拉尔盆地贝尔湖坳陷的一个二级构造单元,主要发育下白垩统。南一段为主要烃源岩层,南二段是良好储集层,大一段泥岩封闭性好、分布广是良好的区域性盖层,三者构成一套下生上储的正常生储盖组合。油气成藏主控因素研究表明,凹陷油气平面分布受有效生烃中心控制,纵向受主力烃源岩层控制,断裂带附近发育的扇三角洲和湖底扇砂体是良好的油气储集体,巴彦塔拉和乌东地区是下步有利勘探地区。

| Abstract: | Wuerxun sag is a second-rank structural unit with Lower Cretaceous in Beierhu depression in Harlaer basin, in which the source rocks are mainly distributed in its Nan-1 member, the reservoir rocks in its Nan-2 member and its well sealed regional cap rocks in Da-1 member, shaping a normal sequence's source-reservoir-caprock assemblage. The hydrocarbon accumulation-controlled factors analysis shows that the hydrocarbon distribution in this sag is controlled by effective hydrocarbon-generating center in plane and by major source rocks in vertical; the fan delta and sublacustrine fans around the fault belt are good reservoirs. Bayantala structural belt and Wudong area are the target areas for further exploration. |
