油藏数值模拟刘月田上机作业
中国石油大学（北京）
研究生《油藏数值模拟》课程上机作业一
油藏的储层参数分布附图所示，W1井网格位置为（4，7），W2井位置为（7，5）。
任务：
独立编制计算机程序完成第五章渗流问题的模拟求解。
具体要求：
（一）使用显式和隐式两种方法。
（二）输出油藏投产后如下时刻的压力分布、w1井底流压和w2井产油量：
初始时刻、10天、1个月、2个月、1个季度、半年、1年、2年、5年；给出压力刚好达到稳定的时刻及其压力分布、w1井底流压和w2井产油量。
（三）对照
（二）中内容，比较分析显式和隐式两种方法的计算过程及结果有何不同。
（四）建议计算过程用国际单位制，输出的结果中压力用MPa，产量用m3/d。
（五）作业完成形式。
要求三个电子文档：
1.综合结果报告，word文档；
2．显式求解方法源程序；
3．隐式求解方法源程序。
