摘要
针对高含硫气藏开采过程中硫的大量沉积引起井筒和采输管线堵塞，导致气井停产，甚至由于“硫堵”，导致管线和设备腐蚀、憋压而遭到破坏的现象，采用统计图版法和热力学方法对元坝长兴组硫沉积发生情况进行了预测，同时针对该气藏的实际井况提出防治工艺及措施。
In light of phenomena of high sulfur content gas reservoirs mining process, causing a large number of deposition of sulfur and mining pipelines wellbore blockage, leading to gas cut-off, even as ＂sulfur blocking＂, leading to corrosion of piping and equip- ment, pressure - and destruction, the use of statistics plate method and thermodynamic method for predicting the situation Yuanba Changxing sulfur deposition occurred while the actual well conditions of the proposed gas reservoir technology and prevention mea- sures.
