摘要
某工程利用GJ—75B(改进型)声幅仪在大直径石油套管内监测了工程井筒散料回填高度及水泥固化过程。实际监测表明:该设备能够在244.5mm的大直径套管内探测密度大于水的任何散料的回填高度,探测高度误差≤0.5m。
Well-filling,height of porous material and cementsofidification process were monitored by GJ-75B(imp-rovedmodel) sonic amplitude meter within large-dia-meter oil casing in enginerring wells of a project.Praitical measure-ment proved that sonic amplitudemeter is able to monitor filling height of any porousmaterial of density higges than waler within φ244.5mmcasing. Moonitoring heigrht error≤±0.5m.
