摘　　要：渤海某油田区块上游平台硫化氢含量增高,连带整个油田区块硫化氢增涨。以改性三嗪化合物、稳定剂、增效剂及有机溶剂组成的液体三嗪类脱硫剂在渤海气田的脱硫过程中,效果要明显优于其他液体类脱硫剂产品。根据评价出效果最优药剂通过选择加药点及加药方式,应用于油田现场。产品应用后,外输天然气达到销售标准,整个油田群硫化氢浓度显著降低,减轻了油田群海管腐蚀风险,保障下游各油田人员安全等效果,具有良好的推广应用价值。The hydrogen sulfide content in the upstream platform of a certain oilfield block in Bohai Sea has increased,which has led to an increase in hydrogen sulfide content throughout the entire oilfield.The liquid triazine desulfurizer composed of modified triazine compounds,stabilizers,synergists and organic solvents has a significantly better effect than other liquid desulfurizer products in the desulfurization process of Bohai Gas Field.According to the evaluation,the most effective agent was applied to the oilfield site by selecting the dosing point and method.After the product was applied,the exported natural gas met sales standards,and the hydrogen sulfide concentration of the entire oilfield group was significantly reduced,reducing the risk of pipeline corrosion in the oilfield group and ensuring the safety of downstream oilfield personnel,which had good promotion and application value.
