在石油和天燃气的钻采中,钻采含硫化氢的酸性气田时,井场中使用的钻采管头及输气集气管线往往会由于受到硫化物应力腐蚀而发生突如其来的破损事故。四川省含硫化氢的酸性气田较多,近年来曾发生多起石油用管在油气井中破损的事故。1965年以来,我们和四川石油管理局勘察规划设计院六室的同志们一起对四川井场中发生的硫化物应力腐蚀破损管具作过一些具体分析。我们认为,了解石油用管在井场中的破损情况,研究其破损原因,对于加强石油管制造过程中的质量管理,不断改善石油管的性能是大有益处的。为此,我们从若干破损管件的缺陷分
In the drilling of oil and natural gas, the drilling and production pipelines and gas gathering pipelines used in well sites often suffer sudden damage due to sulfide stress corrosion when drilling for acid gas fields containing hydrogen sulfide. There are many acid gas fields containing hydrogen sulfide in Sichuan Province. In recent years, more than one petroleum pipe has been damaged in oil and gas wells. Since 1965, we have made some concrete analyzes with the comrades in Room VI of Survey Planning and Design Institute of Sichuan Petroleum Administration about the sulfide stress corrosion cracking tools in well sites in Sichuan. In our opinion, it is of great benefit to understand the damage situation of oil pipe in the wellsite and to study the reason for the damage. It is of great benefit to improve the quality management of the oil pipe manufacturing process and improve the performance of the oil pipe. To this end, we break down a number of defective tubes
