摘要
乌尔逊凹陷是海拉尔盆地最主要的含油凹陷之一。经过多年的勘探,规模较大、埋藏较浅的主体构造带已基本探明,勘探对象由构造油藏转为岩性油藏、复合油藏等。以乌尔逊凹陷乌南次凹为例,通过层序地层分析落实岩性体可能发育的次级层序,然后以“坡折控砂、沟槽输砂”理论为指导,在层序格架控制下落实坡折带和沟槽分布特征,运用地震属性分析,地震正、反演,油气检测技术等方法在坡折带以下及沟槽发育区寻找刻画了一批岩性目标,为乌尔逊凹陷的岩性油藏勘探奠定了基础。
Wuerxun depression is one of the most important oil-bearing sags in Hailaer basin.After years of exploration,the largescale and shallow buried main structural zone has been basically proved,and the exploration object has changed from structural reservoir to lithologic reservoir and composite reservoir.Taking Wunan sub sag of Wuerxun Sag as an example,the possible secondary sequence of lithologic body is determined through sequence stratigraphic analysis.Then,guided by the theory of“slope break sand control and groove transport”,the characteristics of actual slope break and groove distribution are controlled in sequence framework,and the methods of seismic property analysis,seismic forward and inversion,oil and gas detection technology are used to develop the trench below the slope break zone A number of lithologic targets are depicted in the area,which lays a foundation for lithologic reservoir exploration in Wuerxun Sag.
