Study and Application on Indepth Profile Control and Surfactant-flooding

The presented technology of profile control and water shutoff can't meet the need of improvement of inner interference of layer and interference between layers and draw on residual oil where water injection can't reach in the period of highly producing water. IPCS technology was aimed at improving the effection that water shutoff and profile control enhance recovery efficiency factor. This article introduces the inner study and on-the-spot application on IPCS technology.
