影响砂体连通体积因素的定量评价
Keywords: 砂体连通体积,正交试验设计,河流相,储层建模
Abstract:
?砂体连通体积的大小,特别是与井连通的砂体体积大小对于油气田的产量、井位的设计具有十分重要的意义。砂体连通体积的计算包含很多不确定性因素,常规的评价方法需要大量的计算。采用正交试验设计的方法对影响砂体连通体积的不确定性参数进行定量评价,能够极大地提高效率。以河流相储层为例,首先分析了影响砂体连通体积计算的6类不确定性因素,并依据油气田的实际情况,对各个因素设置了3种参数水平。采用正交试验的方法设计了18组模拟方案,分别进行模拟计算,并采用方差分析方法对模拟结果进行分析,对影响砂体连通体积的不确定性参数进行了定量评价。
