摘要
由于蒸汽吞吐、注蒸汽等高温开采,中二北馆5区块稠油采出液中硫化氢浓度不断升高。为了降低联合站硫化氢处理压力,孤岛采油厂针对中二北高含硫化氢井实施集输管线加药处理工艺改进,通过井口的输送管线投加三嗪类脱硫剂,实现集输沿程硫化氢的去除。实施后,孤六联合站入站硫化氢浓度由2 100 mg·m^-3降至500 mg·m^-3,达到联合站脱硫塔处理要求(≤700 mg·m^-3),应用效果较好。
Due to high temperature exploitation measures taken by steam stimulation,steam injection and so on,the concentration of hydrogen sulfide in heavy oil recovery fluid in Zhong′erbei Ng5 block increasingly rises.In order to reduce the treatment pressure of hydrogen sulfide in a united station,Gudao Oil Production Plant improves the dosing process of high hydrogen sulfide wells by gathering pipeline of Zhong′erbei through adding triazine desulfurizer into the well pipeline,realizing the removal of hydrogen sulfide along the gathering pipeline.After the implementation,the concentration of hydrogen sulfide at the entrance of Gu6 United Station is reduced from 2 100 mg·m^-3 to 500 mg·m^-3,which meets the treatment requirements of the desulfurization tower in the united station(≤700 mg·m^-3).The application effect is good.
