用吸水剖面异常确定套损漏失

赵大扶，姜萍．用吸水剖面异常确定套损漏失．测井技术，１９９９，２３（２）：１５０～１５４对于注水井，当套管破损造成注入水出现漏失时，吸水剖面会有不同程度的异常显示特征。文中对套管破损机理进行了分析并对测井曲线异常进行了深入研究，得出确定套管破损的解释方法，为油水井采取相应的防治措施提供了重要依据，对改善注采系统的严重失调以及提高水驱动用程度发挥了很好的作用。此研究成果也拓宽了吸水剖面测井的服务领域

Using Anomaly of Injection Profile Log to Determine Fluid Leakage Due to Casing Damage

For water injection wells,there are, to a different extent, various abnormal indications on injection profile logs when injection water leaks due to casing damage. Causes for the damage are analysed and the anomalies of the log is studied thoroughly, on the basis of which an interpretation method for determining the casing damage is given. This study provides ground for adopting correct leakage prevention measures and plays an important part in decreasing the serious voidage injection imbalance and increasing drivable oil recovery. The method widens the applications of injection profile log.
