摘　　要：塔河油田属于奥陶系油气藏,所产原油物性主要表现为粘度高、密度大、富含硫化氢,进入油田生产系统后,对设备装置、原油储罐、管线等关键要害部位腐蚀较大,往往造成系统不稳定,同时在生产环节中,塔河原油容易逸散出高浓度的硫化氢,对环境和人造成极大的影响和危害。如何结合现有实际情况,降低原油硫化氢含量是需要解决的问题。针对问题,提出了在上游原油集输站库加装静态混合器进行脱硫工艺优化的解决措施,使原油硫化氢含量、脱硫剂单位成本费用两项关键控制指标大幅降低,取得了较好的经济效益和社会效益,具有较强的推广价值和应用前景。Tahe Oilfield is of Ordovician oil and gas reservoir,crude oil produced in Tahe Oilfield has such physical property as high viscosity,high density and rich hydrogen sulfide.After entering oil production system,it seriously corrodes oil treatment units,oil storage tanks,pipelines and other vital parts,which will frequently result in system instability.Also,it often emits hydrogen sulfide with high concentration in production and treatment process,which brings serious effect and harm to environment and human.In order to mitigate such effect and harm,it is very important to reduce hydrogen sulfide concentration in crude oil.For this reason,proposed is such solution as installation of static mixer in upstream crude oil gathering station for desulfurization process optimization.Since the solution is put into operation,such key control indexes as hydrogen sulfide concentration in crude oil and unit cost of desulphurization chemicals have been reduced significantly and good economic and social benefits have been achieved,which shows that the solution has high promotional value and application prospect.
