大港官80地区辫状河砂体构型分析及剩余油分布规律研究

Architectual analysis of braided river sand body and the distribution of remaining oil in Guan80 region of Dagang oilfield

以大港油田官80断块孔一段枣Ⅱ油组为例,应用取心、测井及动态资料,对研究区辫状河储层4级构型单元进行研究;识别辫状河单一成因砂体,并刻画了辫状水道砂体与心滩坝砂体构型单元的空间叠置关系;研究了砂体分布对油水运动的影响作用。

The architectual units of 4th level of braided river reservoir in the studied area were studied by using the core,logging and dynamic data with the zⅡgroup in Guan80 fault block,Dagang oilfield as an example.The space superimposed relationship of architectual unit between the braided channel sand body and the mid-channel bar sand body was depicted through identifing the single genetic sand body of braided river. The effects of sand body distribution on oil water movement were studied.
