摘要
针对泥饼对固井质量的影响和调整更新井固井的技术难点,结合泥浆转化水泥浆技术,配制了多功能完井液,配合高密度矿渣固井液代替纯水泥在调整更新井封固油层,多功能完井液形成的泥饼厚度在小于1.5 mm时能完全固化,可提高第一、二界面的胶结质量,多功能完井液和矿渣固井液相容性好,能提高顶替效率,有效地防止窜槽,经长庆马岭地区中78-5井和南174-5井现场应用结果表明,两口井固井质量均为优质井,而且能大幅度降低固井成本,但高密度矿渣固井液在施工中平均密度低于设计密度,还有待于进一步完善。
Mud cakes on borehole often lead to bad cementing quality. A completion fluid and cementing fluid system was developed based on the MTC technology. Field using showed its advantages as good compatibility, high displacement capacity and low cost, it prevented channeling and bad bonding because of mud cakes.
