| 摘要: |
| 高含硫气田的元素硫沉积不仅直接影响产量,而且腐蚀严重,对气田安全高效生产带来极大危害。研究了以DMDS为主剂、MAT为催化剂的新型溶硫剂体系,在50℃时,100g新型溶硫剂溶解50g硫粉所用时间为1.25min,饱和溶硫量为241g元素硫/100g溶剂,并且与高含硫气田常用的缓蚀剂配伍性良好。通过溶硫剂现场加注试验,元素硫沉积解堵工艺有效率达90%以上。 |

| Abstract: |
| The elemental sulfur deposition of high-sulfur gas field affected production directly and caused serious corrosion,which did great harm to the safe and efficient production of gas field.This paper researched the new dissolved sulfur agent system,which took DMDS as main agent and MAT as catalyst.At 50℃,100 g agent could dissolve 50 g sulfur power in 1.25 minutes.The saturated dissolved sulfur content of agent is 241 g per 100 g,and it has a good compatibility with corrosion inhibitor.The dissolved sulfur agent field tests demonstrated that the broken down process efficient of element sulfur deposition is more than 90%. |
