The injection pressure rose, the injectivityprofile and interlayer contradiction was modulated.
水井注入压力升高，吸水剖面得到调整，层间矛盾得到改善；
2
Injectivityprofile is commonly determined with radioisotope tracer test in water-flood oilfield.
对于注水开发油田，通常使用放射性同位素测井测量注水井的吸水剖面。

The incorporate technology can settle sand control, water plugging and injectivityprofile control in one time and reduce formation damage and operating cost.
