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。
The injection pressure is generally higher in the injection wells of SZ36-1 oil field, resulting in decreasing in water injec- tion, and decline in formation energy, and the oil field development has also been affected. The main reason for injection well pres- sure 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 offluo boric acid system in removing the clog of injection wells has been discussed.
