摘要
用该工艺首次在我国成功地处理了四口注水井。处理后观察到杀菌解堵增注的效果:注水井井口压力下降,注水量增加。单井增注水量平均为1894t,增注有效期平均307天。该工艺施工简便、成本低、成功率高,便于推广。
A new combination process of sterilizing, deplug and waterflood-increasing with sodium hypochlorite in waterflooding horizons has been developed. Its applicability was certified by 4 treatments of injection wells. After treatments the water-intake capacity of injection wells was increased, the pressure at well heat was decreased, and the average duration of stability wster injection was 307 days.
