摘要
提出了利用ＢＰ网络模型确定水淹层解释参数的方法。该方法根据关键井的岩心分析资料和压汞资料共确定了水淹层解释中常用的５ 个参数： 含水饱和度、束缚水饱和度、孔隙度、渗透率和泥质含量， 进而求得了残余油饱和度、水相渗透率、油相渗透率、含水率和驱油效率等有关参数。在此基础上， 对华北油田京１１ 断块２０ 多口井进行了处理， 解释符合率达８０％ 以上。
A method to determine parameters for interpreting watered out zone is proposed by using BP network model The method based on the key well data from core analysis and mercury injection involves determining 5 common parameters: water saturation, irreducible water saturation, porosity, permeability and shale index Then, residual oil saturation, water phase permeability, water phase permeability, oil phase permeability, water cut and oil displacement efficiency are obtained Data from above 20 wells of the faulted block Jing 11 in Huabei oilfield are processed and their coincidence rate is more than 80 percent
