Of low permeability oilfield main aim is to can block or reduce the absorption capacity of the high permeability layer, increase the water absorption of low permeability, and reduce the ineffective injection to adjust the injection profile, the effective expansion of the water flooding sweep efficie

Research into low-penetration with the aim of the major oil fields can block or reduce the high level of absorption of water infiltration capacity, increase the low penetration of the water, reducing the invalid filling up, adjust the water section of the expansion of the water, and drive effective

Studies the low seepage oil field main goal to lie in may seal off or reduce the high filter layer infiltration capacity, increases the low seepage the soakage, reduces the invalid irrigation, the adjustment entry profile, the effective expanded water drive affects the coefficient, the adjustment in

Research of low permeability oil field is primarily aimed at blocking or reducing high-permeability of water-absorbing ability, increase water absorption of low permeability, reduce invalid water adjust of water injection profile, expansion of effective water flood sweep, industrial profiles, reduci
