绥中36-1油田水淹层密闭取心饱和度校正

分析了常规密闭取心岩心分析饱和度的主要影响因素,并对岩性、渗透性、油水总饱和度进行分区间统计,给出了一套基于统计回归的饱和度解析式校正方法,完成了SZ36-1-X井密闭取心饱和度校正。结果表明,该方法简便实用,适用于渤海油田水淹层常规密闭取心饱和度校正。

Saturation correction of sealed coring for water-flooded zones in SZ36-1 oilfield

For conventional sealed coring,the main factors to influence core saturations are analyzed,and interval statistical analyses are made for lithology,permeability and total saturation of oil and water,resulting in a saturation correction methodology based on statistical regression.By this methodology,saturation correction of sealed coring is completed for well SZ361-X,and the results have indicated that the methodology is simple and practical,and quite applicable to the water-flooded zones in Bohai oilfield.
