摘　　要：在一些油藏采油过程中,油藏中存在底水锥进现象,使得油藏的开采存在一定难度,因此.为了抑制底水油藏中的这种现象,油田工作者进行了许多研究,一些方法抑制了底水的上窜。根据镜像法原理推导了水平井底水油藏井网产量公式,并且讨论了底水油藏水平井长度优化参数,以有利于底水驱油藏水平井生产预测研究。推导结果表明,水平井产能及见水时间主要受水平井长度、水平井位置和油层各向异性的影响。In the extraction processes of some pools,the bottom water coning in these oil pools results in some difficulties for extraction.Therefore,in order to suppress this kind of phe- nomenon in the bottom water pool,petroleum engineers have acquired some methods to suppress the coning of bottom wa- ter.The off-taken potential of well pattern in bottom water pool of horizontal well is derived from the principle of image method,and the parameter optimization of the length of hor- izontal well is discussed.It can be concluded that the off- taken capacity and the time of water breakthrough of hori- zontal well are subject to the length and position of horizon- tal well,and the anisotropy of oil pay.
