Abstract
Developing low and extra-low permeability reservoirs becomes more
and more important to the sustainable energy development in China and waterflood
development is the common development mode. But with the oilfield development, water injection well has also exposed some questions gradually, such as the
injection pressure increases, water injection rate decreases and so on. We proposed
a new reservoir protection technology by adding new anti-swelling agent NTW-1
and fluorocarbon surfactant FCS-08 in the injection water. NTW-1 has good antiswelling ability and FCS-08 could change rock surface to neutral wetting. After
successful field application in ShengLi oilfield in china, water injection pressure
reduced by 21.7%, daily water-injection rate increased by 31.8%. it is proved that
the new reservoir protection technology has well reservoir protection effect which
has good decompression and augmented injection function.
