试验一年以后，水井注水压力下降，视吸水指数上升，层间吸水状况得到改善；

After one year, injection pressure dropped and apparent water injectivity index rose, and interbedded injectivity behavior was improved in the injection wells.

海拉尔油田贝301试验区块自全面投入注水开发以来，部分井存在注水压力上升快、吸水能力下降的情况。

Since overall waterflooding staged in the No. 301 Bei pilot area in Haila'er oilfield in 2004, rapid injection pressure rise and injectivity drop have occurred in some wells.
