摘要: 针对商河油田商三区块注水面临的地层堵塞问题, 进行了商三区块储层堵塞机理理论研究和实验研究, 进而对酸化解堵增产措施进行了分析。结果表明, 注入水水质不合格及注入水与储层的不配伍造成了注入水堵塞地层; 储层岩样解堵实验推荐用盐酸+低浓度土酸+多氢酸体系来改善沙二下储层; 缩膨剂缩膨效果评价实验表明, 缩膨剂能恢复地层的渗透率。矿场试验表明, 质量分数为1 2%盐酸+质量分数为1%氢氟酸+质量分数为5%多氢酸+缩膨剂的复合解堵工艺能明显改善储层, 达到注水井增注、 油井增产的目的。

Abstract: Shang 3 region in Shanghe oil field has the problem of formation plugging when water injection. This paper addresses the study on theoretical and experimental research of Shang 3 region plugging mechanism and plugging removal techniques. The result show that the injected water quality substandard and injected water is not compatible with the reservoir causes blockage formation. Reservoir rock samples plugging experiment recommends using hydrochloric acid+multihydrogen acid+mud acid system to improve lower members of Es2. Shrink swelling agent evaluation experiment show that shrink swelling agent can restore formation permeability. Field tests show that hydrochloric acid+low concentration mud acid+multihydrogen acid +shrink swelling agent composite plugging process can significantly improve reservoir, achieve the goal of increasing production and augmented injection.
