摘要
针对稠油油藏热采开发的特点 ,采用在吞吐井周围进行局部加密的方法 ,既兼顾稠油油藏热采特点 ,保证了拟合计算的合理性 ,又减少网格节点数 ,节省计算时间 ,从而实现了锦 90块兴I组油层全块的模拟。从宏观上和整体上查明了锦 90块兴I组油层的目前油层动用状况和剩余油分布规律 。
Simulation on whole pay zones of group I in Jin 91 block is realized using the method of local refinement around the steam stimulation wells. The method ensures the rationality of matching calculation considering the characteristics of thermal recovery in heavy oil reservoirs and saves the calculation time for cutting down the grid number. Present recovery status of the pay zones and distribution rule of the remaining oil in group I of Jin 91 block are made clear as a whole macroscopically. It has directive significance on next development work of this block.
