摘要

近期多个油田都对油井伴生硫化氢采取了单井井口脱硫的源头治理方式。受井筒温度、采出液复杂性的影响,目前存在加药量大、成本高的问题。以廉价的空气作为脱硫剂,建立模拟实验流程,利用管式反应器,研究了流速、气液比和反应器内构件(SK型、SV型和拉西环)对硫化氢转化速率的影响。结果表明,硫化氢转化速率随着管道内流速和气液比的增加而增加,SV型内构件下硫化氢的转化速率较快。建立管式反应器,对GD2-25P530井开展了空气氧化脱硫现场试验,脱硫率达到了80%以上,处理成本节约70%以上。
        Recently,single well wellhead desulphurization,a source control method,has been employed by many oilfields to treat with hydrogen sulfide associated with oil wells.There exists problems such as high agent dosage and high cost for this method,affected by the temperature at wellbore and the complexity of extraction liquid.A simulation experiment process is established by using cheap air as desulfurizer,and a tubular reactor is utilized to study the effects of velocity,gas-liquid ratio and inner components(SK mixer,SV mixer and Raschig ring) of reactor on conversion rate of hydrogen sulfide.Study results indicate that the conversion rate of hydrogen sulfide rises with the increases of velocity and gas-liquid ratio,and can reach the highest in the reactor with SV mixer.Finally,the spot test of air oxidation desulphurization in tubular reactor is carried out on GD2-25 P530 well,the desulphurization rate exceeds 80% and the processing cost is cut down by more than 70%.
