高含硫气井的开采与生产管理是目前高含硫气田开发的重点和难点。由于高含硫天然气具有H_2S和CO_2等腐蚀性介质含量较高、水合物形成温度较高、而且在井下及地面易析出单质硫等特性,使其对设备管道造成严重堵塞和腐蚀,对生产、作业和经济效益影响较大。针对云安厂气田大猫坪长兴组云安012-1、012-2两口高含硫气井生产情况及技术管理进行分析,找出存在的问题,提出了应对措施和管理要求,以供决策参考。
The exploitation and production management of high-sulfur gas wells are the key and difficult point in the development of high-sulfur gas fields. Due to the high content of H 2 S and CO 2 and other corrosive media and the high formation temperature of hydrate, and the easy precipitation of elemental sulfur in the underground and underground, the high-sulfur natural gas causes serious blockage and corrosion on the equipment pipeline, Homework and economic benefits have a great impact. According to the analysis of the production situation and technical management of two high-sulfur gas wells in Yunan 012-1,012-2, Changping Formation, Changping Formation, Datianping, Yunan Gas Plant and find out the existing problems, the paper put forward the countermeasures and management requirements for decision-making .
