| 摘 要： | 绥中36-1油田注水井注入压力普遍偏高,导致注水量下降,地层能量亏空,油田开发受到影响。注水井注入压力上升的主要原因是地层受到堵塞,此文从注水水质、储层敏感性和工艺措施三个方面分析了绥中36-1油田注水井堵塞的原因,提出了解除注水井堵塞的对策,并以D17井和E7井为例论述了氟硼酸体系对绥中36-1油田注水井解堵的有效性。

| Abstract: | The injection pressure is generally higher in the injection wells of SZ36-1 oil field,resulting in decreasing in water injection, and decline in formation energy,and the oil field development has also been affected.The main reason for injection well pressure rise in SZ36-1 oil field is the formation plugging.In this paper,the main three reasons for injection well clogging in SZ36-1 oilfield have been discussed,including the water quality,reservoir sensitivity and process measures,and the measures to remove the clog of injection wells in SZ36-1 oil field have been put forward.With D17 well and E7 well in SZ36-1 oil field as an example,the effectiveness of fluo boric acid system in removing the clog of injection wells has been discussed. |
