含H_2S油田地面工程设计探讨

Discussion on the Surface Engineering Design in H_2S Oilfield

随着长庆油田的不断开采,很多油区原油中陆续发现了H_2S气体。H_2S不仅腐蚀性强,对设备、管线腐蚀速度快,而且毒性大,对操作人员的人身危害大。通过提高站场密闭工艺和自控水平,减少工作人员操作程序,降低H_2S的危害,利用HYSYS软件对该接转站原油组分及伴生气组分进行模拟,通过模拟选择合适的管材,以达到油田高效开发和安全生产的目的。

H_2S has been found in many regions in Changqing Oilfield during the continuous exploitation,which has got strong corrosivity,and also toxic,severely harmful for operators.The risk brought by H_2S could be reduced through improving the level of station closed process and automatic controlling, and reducing the operating procedure. Using HYSYS software to simulating the composition of crude oil and the fraction of associated gas, and then select the appropriate pipe.On this account,the development of the oilfield could be more efficient,and the production could be more safe.
