摘　　要：本文用数值模拟方法,按照大庆油田的油层条件,系统研究了水驱特征曲线的一般特征、出现直线段的时间及直线最小适用范围,同时重新评价了小井距试验区的水驱特征曲线,从而为在本油田正确使用水驱特征曲线提供了依据。文中用中期采油量倍增法估算的可采储量也可为开发决策提供参考数据。<ABSTRACT> The general aspects of water drive-characteristic curves and the time the straight line section appears and its minimum applicability, based on the oil reservoir conditions of Daqing Oilfield by using the numerical simulation method, are investigated in this paper. Also, the water drive-characteristic curves of the test field 'Close Well Spacing Area' are reevaluated. The numerical results pre sented in the paper, provide the basis of an argument for properly using the characteristic curves in Daqing Oilfield. The estimated recoverable reserves deri ved from the middle stage produciton-incremental method can provide reference data for making a strategic decision on the oilfield development.
