Natural gas well gas condensate purifying agent and preparation method thereof

The invention relates to a natural gas well gas condensate purifying agent and a preparation method thereof. The natural gas well gas condensate purifying agent is prepared from the following raw materials in parts by weight: 20-30 parts of alkyl dimethyl benzyl ammonium chloride, 10-15 parts of polyoxypropylene polyoxyethylene propylene glycol ether, 5-10 parts of sodium hypochlorite, 4-8 parts of sodium percarbonate, 1-3 parts of sodium hydroxide, 0.5-1.5 parts of a stabilizer and the balance of water. The preparation method comprises the following steps of: adding a half amount of the water into a reaction kettle; starting a stirrer; adding the alkyl dimethyl benzyl ammonium chloride, the polyoxypropylene polyoxyethylene propylene glycol ether and the stabilizer; heating an obtained mixture to 40-55 DEG C; continuously stirring for 30-60 minutes; cooling to room temperature; adding the rest water, the sodium hypochlorite, the sodium percarbonate and the sodium hydroxide; continuously stirring for 20-40 min
