摘　　要：高含硫气田地面集输系统的硫堵塞现象是抑制高含硫气藏产能充分释放的行业难题。结合LJZ气田生产过程中地面集输系统硫沉积规律及治理情况,建立了一种适用于高含硫气田地面集输系统的硫沉积定量预测方法。通过实践验证,证明该方法计算硫沉积量与实测量误差较小,能够满足气田生产需要,为科学组织生产提供了指导。The phenomenon that sulfur deposition blocks the surface gathering and transmission system and thus suppresses the productivity of high sour gas reservoirs is a challenge faced by the industry.A method for quantitative prediction of sulfur deposition suitable for the surface gathering and transmission system of high sour gas field is established based on the literature research and the study of sulfur deposition and its treatment in LJZ gas field.It’s proven through practice that there is small difference between the calculated sulfur deposition amount and the actual amount,which means the method can meet the needs of gas field production and guide the organization of production in a proper manner.
