The invention relates to the technical field of oil and gas field sulfur removal agents, in particular to an oil and gas field organic composite efficient sulfur removal agent and a preparation method thereof. The sulfur removal agent is prepared from, by mass, 40-50% of a triazine derivative, 10-20% of methyldiethanolamine, 7-10% of an auxiliary solvent, 5-8% of triethylene glycol and the balance of water. The preparation method comprises the following steps of: adding methyldiethanolamine, a triazine derivative and triethylene glycol into a reaction kettle, stirring at a high speed, adding an auxiliary solvent, finally adding water, uniformly stirring at a low speed, and discharging. The obtained sulfur removal agent can significantly reduce the content of sulfides in oil and gas fields, and meanwhile, the sulfur removal agent has good stability under different use conditions. 本发明涉及油气田除硫剂技术领域，具体涉及一种油气田有机复合高效除硫剂及其制备方法，所述除硫剂，以质量分数计，包括以下组分：三嗪衍生物40～50％、甲基二乙醇胺10～20％、辅溶剂7～10％、三甘醇5～8％和水为余量；所述制备方法为将甲基二乙醇胺、三嗪衍生物、三甘醇
