Both the shop experiment and field test showed that the wettability alteration agents have the ability to reduce the injectionpressure and enhance oil recovery.
室内实验和矿场试验都说明，润湿性反转剂具有降压增注和提高原油采收率的效果。

Major factors leading to oil flow away are high pressureinjection and unbalance of injection and production.
导致原油外流的主要因素是高压注水和注采不平衡引起的。

The result shows that cyclic water injection may be more effective if increasing oil-water percolation rate, standup pressure time and water holdup coefficient.
