Water-oil volume ratio of edge-bottom water reservoir presents the capacity of natural energy. It's the key to determine reservoir development scheme and strategy.
边底水驱油藏水油体积比表征了天然能量大小，是确定油藏开发方式和开发对策的关键。
So, after reservoir watering out as edge water and bottom water enters, the gas phase permeability will decrease greatly, and strong water lock effect will happen.
因此，当边水和底水进入储层发生水淹后，气相渗透率将极大降低，存在较强的水锁效应。
In heavy oil reservoir with active edge and bottom water. the incursion of edge and bottom water has a serious impact on the production performances during steam huff and puff.
具有活跃边底水的稠油油藏，在其蒸汽吞吐过程中，边底水侵入给开采动态带来了严重的影响。
This model is applicable to solution gas drive reservoir without edge and bottom water.
该模型适用于无边、底水的溶解气驱油藏。
The zone immediately beneath the hydrocarbons is referred to as the bottom water, and the zone of the reservoir laterally adjacent to the trap as the edge zone.
直接坐落烃类以下的区带称为底水，横向与圈闭相邻的区带称为边际地带。
The edge and bottom water energy is sufficient in the heavy oil reservoir of Shanjiasi oil field, and its steam soak process is complicated.
单家寺油田稠油油藏边底水能量充足，蒸汽吞吐过程较复杂。
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.
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。
Then the geological parameters such as reservoir thickness, formation permeability, oil viscosity, oil saturation, edge water and bottom water are researched by using the optimal well pattern.
再利用最优井网研究油层厚度、地层渗透率、原油粘度、含油饱和度、边底水等地质参数对开采效果的影响规律。
It concludes that horizontal wells are not suitable for bottom water reservoir development, but advantageous for edge water reservoirs with thin layer, low permeabi.
因此，水平井并不适合底水油藏的开发，它适合于薄层、低渗和稠油等直井产能较低的边水油藏。
It concludes that horizontal wells are not suitable for bottom water reservoir development, but advantageous for edge water reservoirs with thin layer, low permeabi.
因此，水平井并不适合底水油藏的开发，它适合于薄层、低渗和稠油等直井产能较低的边水油藏。
