摘要: 继续搜集和提出了10种水驱特征曲线表达式,使水驱特征曲线表达式总数达到了50种。这10种水驱特征曲线表达式中,对于一般的水驱油田,使用价值较大的是第45种水驱曲线,其fw-R*关系曲线为凹形,曲线参数的求取也比较方便和容易。第41、47、48、50种水驱曲线都是广义水驱特征曲线,其中第41种水驱曲线(即王俊魁水驱特征曲线)有较大的实用价值,第50种水驱特征曲线有一定使用价值。第47种水驱特征曲线参数求解较繁复;第48种水驱特征曲线驱替特征极为罕见,它们的实用价值很小。

Abstract: The paper continued with the previous study and collected and introduced 10 relationships on water dis- placement curves, adding the total to 50. Among these 10 proposed relationships, for Ordinary water-flooding oilfield, No.45 water displacement curve is more valuable,with its fw-R* relation curve being concave—shaped, and it is more convenient and easier to acquire the solution of the curve parameters. No.41, 47,48 and No.50 curves are all generalized curves among which No.41 (namely WANG Jun-kui water, displacement curve) has more practical value while No.50 has a certain applicable value. No.47 curve is more complicated to solve for the parameters, while No.48 has a very rare water-displacement characteristics, and is of little practical value.

Key words: Water displacement, Displacement curve, water cut, recoverable reserve, recovery percent, application
