边水驱动 [
biān shuǐ qū dòng]
[油气] boundary water drive
- 气藏边底水不活跃,气水系统连通范围较小,水体驱动能量有限;
The border water is not active, the system of gas and water is small and driving power of water is poor. - 油藏驱动机制可能为边水和底水两种类型的结合。
The driving mechanism for the Midale pools is interpreted to be a combination of edge water and bottom water drive systems. - 含油饱和度受油藏边界和构造形态控制,油藏南部边缘和局部构造低部位原始含水饱和度高,但不形成有效边底水驱动。
Initial oil saturation is controlled by the reservoir boundary and structural. Parts of the reservoir with high initial water saturation dose not form effective edge and bottom water drive.
