Water injury treatment agent

Water damage treatment agent for oilfield development in the high clay content of the reservoir, the reservoir structure loose cemented poor performance, low-permeability water-sensitive, water lock, changes in the physical properties of crude oil and operating pollution capacity to reduce the problem.

It can effectively play a release of water damage, and factors such as pollution caused by oil wells, improve reservoir, increase penetration and to increase oil production capacity or restore water injection efficiency.

Physical and Chemical Indicators:

Ø  Exterior: Uniform liquid

Ø  Density: 0.90-1.05

Ø  Surface tension: ≤30（8% Water-soluble）                          

Ø  Interfacial tension: ≤0.5

Ø  Permeability improvement rate (water-soluble as compared with the 2% KC1):                                  ≥25%

Ø  Compatibility with water quality: Dissolved in formation water, sea water, to form a transparent liquid
