摘　　要：超稠油的开发在我国已经保持了13年百万吨的产量规模,由于超稠油高密度、高黏度、高凝固点的物质特点,针对其独特的打开方式主要以蒸汽吞吐为主。在开发过程中容易产生高浓度硫化氢气体,该种气体对工作人员的身体健康以及周边环境都容易产生较大的影响。在蒸汽吞吐井工作时所产生的硫化氢浓度相对较低,但在之后SAGD、蒸汽驱油井工作阶段,长期的高温高压将不断提升硫化氢的浓度。本文将着重分析超稠油开发中硫化氢的具体成因,针对开发中的实际问题提出具体的治理解决技术。The development of super heavy oil has maintained 13 million tons of production scale in China.Because of the material characteristics of high density,high viscosity and high solidification point of super heavy oil,steam huff and puff is the main way to open super heavy oil.High concentration hydrogen sulfide gas is easily produced in the development process,which has a great impact on the health of staff and the surrounding environment.The concentration of hydrogen sulfide produced in steam huff and puff wells is relatively low,but in later stages of SAGD and steam flooding wells,Long-term high temperature and high pressure will continuously increase the concentration of hydrogen sulfide.This paper will focus on the analysis of the specific causes of hydrogen sulfide in the development of super heavy oil,and put forward specific treatment and solution technologies in view of the actual problems in the development.
