There happens salt filth during gas production in Wen No.23 gas field. Some wells are seriously affected by the filth. The shooting passes are often blocked by salt lock and salt block, which may influence the output of the gas. According to the chemical analysis of the salt filth in this gas filed and the survey made to investigate the effects of the conventional salt-washing techniques, this paper introduces a new complex detergent which has good results after testified in experiment. This new detergent can wash out the salt filth completely.
