渤海某油田产出油气水三相流中H2S含量较高,需经过脱硫处理后,才能达到油、气外输标准。药剂OST-1122现场用量较大,药剂成本、人工操作成本都较高。药剂OTS-213为三嗪类高效脱硫剂,脱硫效果显著。本次研究将其应用到现场进行评价,结果表明,脱硫药剂OTS-213效果明显优于OST-1122。同等工况条件下,OTS-213药剂的用量仅为OST-1122的60.00%,且稳定性明显占优;同时OTS-213药剂与H2S的反应后产物具有良好的缓蚀作用。
The H2S content in oil-gas-water three-phase flow produced by one oilfield in the Bohai Sea is high, and it needs to go through the desulfurization treatment to reach the oil and gas output standards. OST-1122 dosage larger on-site, pharmaceutical costs, labor costs are higher. Pharmacy OTS-213 is a triazine efficient desulfurizer, desulfurization effect is remarkable. This study will be applied to the site for evaluation, the results show that the desulfurization agent OTS-213 is significantly better than OST-1122. Under the same working conditions, the dosage of OTS-213 was only 60.00% of that of OST-1122, and the stability was obviously dominant. Meanwhile, the reaction of OTS-213 with H2S had a good inhibition effect.
