摘　　要：在高含硫气藏开采过程中,地层、井筒和地面集输管线都会出现硫沉积。硫的大量沉积会引起地层、井筒和集输管线堵塞,导致气井产能急剧下降,甚至停产,而一旦生产管线中形成"硫堵",管汇极有可能因腐蚀、憋压等遭到破坏,造成硫化氢等有毒气体的泄露和扩散。了解元素硫的性质、硫沉积的机理,采取预测与防治技术是高含硫气井开采中的一项重要任务。In high-sulfur gas reservoir process,the formation,wellbore and surface gathering pipelines would appear sulfur deposition.Sulfur deposition caused a large number of strata,wellbore,and gathering and transportation pipeline blockage,leading to a sharp decline in gas production,or even stop production,but once formed in the production pipeline,＂sulfur plugging＂ manifold was very likely due to corrosion,such as the destruction of pressure,resulting in hydrogen sulfide and other toxic gases leaked and spread.Understanding of the nature of elemental sulfur and sulfur deposition mechanism,prediction and control techniques to a high-sulfur gas exploration was an important task.
