摘要
通过对滨古14-侧平1水平井储层孔渗、伤害程度、高温等的认识,有针对性地开发和评价了长效酸化缓蚀剂、高效酸化缓速剂和转向剂,筛选出适合该水平并酸化解堵的低伤害酸液体系。采取了"多级注入+缓速酸+暂堵液"的酸化工艺方案,并对施工工艺进行了优化。滨古14-侧平1水平段为裸眼完井,长达200m,酸化施工中采用上提普通油管工艺,而不是连续油管,这类工艺方式的酸化在国内属首次,具有一定的风险性,也对将来的裸眼水平井酸化具有较大的借鉴意义。
Abstract
According to analyzing reservoir characteristics,damage and high-temperature of Bingu14-Ceping1 Well, we develop and evaluate corrosion inhibitor in long-time, effective acid retarded agent, and diverting agent. The low-damage acid fluid system for using acidizing Bingu14-Ceping1 Wen is developed. The "Multiple Injection and Retarded, Acid and Diverting Acid" program is dried out in acidizing treatment. The design parameter was optimized and designed. The effect was evaluated.
