Forward pressure drive technology
Higher injection pressure is needed, increasing the injection pressure from 30 mpa to 45 mpa or more.
It breaks the conventional water injection method and overcomes the problem of "no injection in, no production out" in low permeability reservoir block.
The pressure drive water injection technology has the advantages of enlarging pore throat radius, increasing percolation distance, redistributing remaining oil, and quickly and effectively replenishing formation energy.


Reverse pressure drive technology
It has the technical advantages of wide spread range, low seepage resistance, small loss along the way and high construction efficiency.
Capable of water flooding development in extremely low permeability blocks.
Replenish formation energy while flushing pore remaining oil.
