油水井验窜技术研究

针对目前油水井夹层验窜工艺精度不高,特别是井口溢流量大或无溢流的井无法准确判断夹层窜槽情况的技术现状,通过在现场研究应用高精度层间夹层验窜工艺和层内夹层验窜管柱,将采油工艺和高精度测试仪器紧密结合起来,大大减小了井口压力和溢流变化量的测量误差,达到了提高油水井验窜工艺精度的目的。

Research on oil/water well channeling verification technology

Current technology for oil/water well channeling verification is not accurate enough,especially for wells with high overflow or no overflow at wellhead,it is difficult to determine interbed channeling situations.Field research has been conducted to apply high precision interformational bed channeling verification process combined with intraformational bed channeling verification pipestring,a combination of oil production technology with high precision testing instrument,thus greatly reduced measurement errors of wellhead pressure and overflow rate and improved the accuracy of channeling verification for oil/water wells.
