| 摘 要： | 推导和筛选了两种逐年计算水驱油田可采储量的公式。一种是适用于水驱层状油田的方法五水驱特征曲线及相应的逐年计算可采储量公式;另一种是适用于底水灰岩油田的方法九水驱特征曲线及相应的逐年计算可采储量公式。这两个公式大大简化了已有的逐年计算水驱油田可采储量的方法,因而有很大的实用价值。算例表明计算结果是可信的。

| Abstract: | Two formulas for calculating recoverable reserves of waterflooding reservoirs on a year basis
are derived and screened. One of them is method 5 water displacement curve, Lp/Np=a bLp,which
is used in waterflooding reservoirs,and corresponding formula for calculating recoverable reserves
on a year basis ;The other is method 9 water displacement curve Lp/Np=a bWp .which is used in
bottom water carbonate reservoirs, and corresponding formula for calculating recoverable reserves
on a year basis. Both formulas greatly simplify the present methods for calculating recoverable re
serves on a year basis,so they have a large application value. Examples indicate that the calcula
tions are were reliable. |
