| 摘 要： | 针对西峰油田长8油藏低渗、细孔喉、砂岩泥质含量高等储层特点,分析了储层堵塞的原因,通过理论及试验优化出了本区块酸化增产的酸液配方。使用土酸酸化角井成功率相对较高,边井成功率低,复合有机酸酸化增产技术从应用效果看好于土酸酸化,为该地区措施提高单井产量积累了一定宝贵经验。

| Abstract: | Chang 8 reservoir in Xifeng oilfield is a low permeability reservoir with fine pore throat and high shale/sand ratio.The cause of reservoir plug was analyzed and acidizing fluid formula of acid stimulation in the block was optimized through theory and experiment.Results showed success rate of applying mud acid to stimulate corner wells is relatively higher than that of edge wells.The application effect of compound organic acid is better than mud acid which provided experiences for individual well production increase in Xifeng oilfield. |
