摘要: 油井井底和近井地带地层结垢,油层内部粘土质点的迁移、堆积、膨胀导致油层渗流条件变差,这是造成克拉玛依百口泉油田产液量大幅度下降的主要原因。采用酸化工艺改善油层渗流条件,使产液量和产油量都有大幅度提高。采取酸化措施前应先找水、堵水。实践表明,来用胶束酸酸化效果最佳。

Abstract: Devastation of percolation condiuon in oil-searing zones resulting from scaling in bottom hole and near-well bore formation as well as fine migration accumnuiatior and swelling within reservoir is the major averse control onificant decline in fluid production of Baikuquan oilfield. Experiments show that percolation condition of oil-bearing zolies can be improved using acidizing technique and then fluid production can increase oy a wide margin. Such operations as water detection and blocking should precede acidizing treatment. The cases study showed that the optimum can be obtained with micellar acid acidizing.
