摘  要：
萨北开发区北二西东块二类油层井层系组合方式为萨Ⅱ组。与相邻区块开采层系不统一,导致衔接区域注采关系不完善,并且二类油层萨Ⅲ组未组合进行三次采油开发,区块整体缺少一套上返层系,接替潜力小。为便于油田开发整体调整,最大限度挖掘剩余潜力,依据油层发育特点,根据层系组合原则开展二类油层层系优化,按照先下后上的次序,分萨Ⅱ10-16+萨Ⅲ和萨Ⅱ1-9两段进行调整。调整后萨Ⅱ10-16+萨Ⅲ层系组合与萨北开发区二类油层井整体组合方式一致,且能有效动用萨Ⅲ组储量,组合层系厚度适中,隔层分布稳定。借鉴三元复合驱矿场试验认识,结合数值模拟成果,优化三元复合驱注入参数,预计调整后,增加可采储量159.15×10~4t。

摘  要：
The stratigraphic combination in the east block of Beierxi Area of the north Saertu Development Area was of SⅡ Oil Group.It was not consistent with the development strata in the nearby block,thus an imperfect injection-production relationship was induced.And SⅢ Oil Group as Class II Reservoir was not in the group for Tertiary oil recovery,therefore there was lacking of a set of upward strata,the development potential was limited.For the convenience of overall adjustment of oilfield development and tapping the potential of remaining oil at the maximum level,based on the reservoir development characters and the principle of strata combination,the ClassⅡ Reservoirs were optimized.To the order of bottom up,it was divided into 2sections,such as SⅡ10-16+SⅢand SⅡ1-9for zoning adjustment.After adjustment,the combinations of the both sections were consistent,and the reserves in SⅢ could be effectively produced,it indicated that the thickness of combined strata was appropriate with stable distribution of interlayer.Based on the understanding of ASP field test and the result of numerical simulation,the injection parameters of ASP are optimized.It is estimated that after the adjustment,159.15×10~4t of recoverable reserves can be raised.
