可控凝胶封窜堵漏技术在江汉油田的应用

Application of Channeling Plugging Technology with Controllable Gel in Jianghan Oilfield

油田开发进入中后期,油水井井况日益恶化,套管漏失的问题越来越严重,治理难度大。特别是浅层的套管漏失,问题尤为突出。通过可控胶凝封窜堵漏技术,解决了水泥浆封堵工艺难以堵漏的现实问题,促进套损治理工作“提质增效”。

In the mid-late stage of oilfield development,the well conditions in oil and water wells are deteriorating day by day,and the failure of casing leakage is becoming more and more serious.Especially in shallow casing leakage,the failure is particularly prominent.By carrying out the channeling plugging technology with controllable gel,the difficulty of plugging with the slurry plugging technique is addressed,so as to facilitate the effective treatment of casing failures.
