| 摘 要： | 油田注水井地层堵塞原因很复杂,和注水中的微生物、悬浮物有关.杀菌增注试验处理后,井底水杀菌率达100%;H_2S 和油类全部去除.杀菌后连续注水一个月,地层水中各种菌数量仍比杀菌试验前少.2903井 H_2S 去除率仍是100%,油类和 SS 去除率为99%和68%.28413井 H_2S 去除率为63%,油类和 SS 去除率为60%和67%.注水量和杀菌前比较,提高了204.7%和318.5%;注水量显著增加.

| Abstract: | Formation plugging is common in water injection wells.The responsible causes for it are complicated.It relates to microbe and suspending substances in the in- jected water.After killing bacteria and increasing water injection,the ratio of bacteria killed is up to 100%,H_2S and various kinds of oil at the well bottom were eliminated completely.After that water injection continued for a month,the amount of various bac- teria in the formation water is still less than the original amount.H_2S was reduced by 100% in Well 2903,oils and SS were reduced by 99% and 68% respectively.In Well 28413,H_2S was reduced by 63%,oils and SS by 60% and 67% respectively.The amount of water injected increases by 204.7% and 318.5%.The injected water increases obvi- ously. |
