摘要
过套管地层电阻率(CHFR)测井能够测量套管完井后的储层电阻率,根据其与初期裸眼井测井电阻值的差别可以快速判断和认识多层合采井各层段水淹情况、油水界面和剩余油潜力分布,实现了在生产过程中对剩余油饱和度的多次定量监测。过套管地层电阻率测井资料结合油藏数值模拟可以实现动静态资料的交互验证,对南中国海惠州油田群开发中后期剩余油挖潜、提高油田采收率发挥了重要作用。
CHFR could be used to measure reservoir resistivity after cased hole completion,based on the resistivity difference of initial opened hole logging,the water out,oil and water contact and remaining oil distribution in commingle production of multi-layers could be rapidly judged and recognized,therefore multiple and quantitative detection of remaining oil saturation could be conducted in production.In combination of CHFR data with reservoir simulation the cross approval of dynamic and static data could be implemented.It plays an important role for tapping the potential and enhancing oil recovery at the late stage of oil production in Huizhou Oilfield Group in South China Sea.
