摘要(Abstract):
根据近几年化学调剖技术在现场实际应用情况 ,从实际统计分析结果和理论研究两个途径 ,对确定调剖前层间吸水差异的最低界限、调剖后主要吸水层相对吸水量下降幅度的最低界限、合理调剖半径、调剖剂用量的定量化及化学调剖优化设计方法等进行了研究。得到 5条认识 :调剖前吸水剖面上两类油层相对吸水量比值大于 0 7时 ,调剖有效 ;化学调剖使主要吸水层相对吸水量下降幅度在50 %时 ,能改善吸水剖面 ;调剖后主要吸水层与差油层相对吸水量比值小于 0 4时 ,能明显改善吸水剖面 ;当调剖半径在 3~ 4m时 ,调剖效果持续时间可达 4 0 0d以上 ;当调剖剂用量达到 50m3 之后 ,目的层吸水量下降幅度趋于平缓。
According to the field application of chemical profile control technique in recent years, this paper studies the lowest boundary of interlayer water adsorption before profile control, the lowest boundary of the decline of water adsorption in the main water adsorption after profile control, reasonable profile control diameter, quantification of profile control agent and optimized design method of chemical profile control through statistic analytic result and theoretic study.
