摘要
前积油层的相域划分和小层对比极大地影响着油藏的注水效果和采收率,尤其象那些低角度薄前积油层由于规模小在地震剖面上无明显的前积反射,因而几乎还没有有效的方法来搞清每个前积叶砂体的空间展布。桩52块近岸浊积扇油藏就是一例。应用基准面旋回高分辨率层序地层学原理,结合三维地震解释,对桩52块油藏小层重新对比可发现它是由堆积在“三沟两梁一面坡”的深~半深湖地理背景上的20个叠瓦状排列的前积叶砂层所形成,而不是以前对比所认为的由全区分布的4个平行的浊积砂层组成。
Facies tracts division and correlation of progradational oil beds extremely affect the water injection response and recovery efficiency of reservoirs.Especially as to those low-angle and thin progradational oil beds which do not occur progradational reflections on seismic profiles,there is no effective method of finding out spatial distribution of every progradational bed sandbody.One example is the proximal turbidite fan reservoir of Zhuang 52,Shengli Oilfield.After the research on base-level cycle high resolution sequence stratigraphy incorporated with 3D seismic interpretation,it is found that the reservoir turns out to be composed of 20 progradational lobes of turbidite sandbodies,instead of consisting of 4 sandbeds considered before.
