摘　　要：渤海的CB油田为典型的稠油油田,目前已进入高含水阶段,油田后期稳产主要通过提液措施。运用多元回归方法分析基于均匀设计法的数值模拟结果,建立稠油底水油藏增采幅度与提液时机和提液幅度之间的关系,确定了合理的提液时机和提液幅度。研究结果表明,对于渤海CB油田来说,含水60%时提液最佳,合理的提液幅度为提液前产液量的1.3倍左右,提液增油效果最明显。该研究应用于矿场实际生产中,取得了明显的增油效果。CB oilfield in Bohai Sea is a typical heavy oilfield.At present,it has entered the stage of high water cut,in the later period of oilfield,lifting liquid is the main way to stable production.Used multiple regression method to analyze the numerical simulation results based on the uniform design method,the relationship between the increasing production range and the extracting time and lifting liquid extent of heavy oil bottom water reservoir is established,the reasonable lifting liquid time and the extracting range are determined.The results show that for CB oilfield in Bohai Sea,the extraction is the best when the water content is 60%,the reasonable extraction range is about 1.3 times of the liquid production before the extraction,the effect of increasing effect oil by lifting liquid.This study has been applied to the field practice,and has achieved obvious effect of increase oil.
