The biological Acidity technology is a new environmental protection agent who got a high attention in oilfield development area at home or abroad. Just like Biological Enzyme technology, the product could be fully biodegraded which has a practical sense under current high attention of environmental protection.
The biological Acidity is a high performance Biological active acidity which could abundantly solve the question of the oil shale rock sedimentary fouling, clogging reservoir to decline in output caused by Fouling of inorganic salts, iron compounds, heavy hydrocarbon, biofilm, because of Formation pressure, temperature, lower crude oil degassing, bacterial metabolism aggregation during the Petroleum exploitation. The technology is quite fit for acidification in oil recovery, it has the effect of clearing the blockage and increase matrix permeability, could increase oil well output. More importantly, this technology fully reflect the highest reservoir protection characteristics of inorganic plugging removal, the  agent corrosive is quite low, does not need to back row, could directly enter into the sea pipe flow, gathering system. The technology advanced is quite apparent.   
The Biological acidity has got the abundant approval in many oil field uses. After use Biological acidity plugging agent, the output has increase 26MT/well, water well increasing injection rate is 168%. The using quantity is less than normal acidity, does not need back row, simply construction, and valid period is longer. It has successfully treated more than 300 wells by using biological acidity Plugging agent at home or abroad.
The technology characteristic,
* Clean and environmental protection 
* The effective solution of deep plugging
* Good Reservoir protection (low surface tension, wettability, cleanup, antis welling stabilizing the sand)
* long period of validity
* No harm the skeleton, slow sand reservoir
* No corrosion to pipeline equipment
* No affect the technology system,
* Simple Process, extruded effect   
* No second precipitation,
