QXJ - 01 nontoxic chemical cleaner has been made out
by scale sample analyzing. The reasonable amount of using
QXJ - 01 is defined after a series of experiments ,such as H2S
gas absorption , scale dissolution ,oil removal result ,corrosion
rate ,etc. ,and by it ,We can safely clean the water injection
steel lines. This technology would be also helpful for all the
scaled steel lines in the oilfield system.
