摘要:
国外某厂家生产的130ksi钢级连续管在新疆某含H2S井中作业时发生了断裂失效事故,为预防和减少连续管在使用过程中失效事故的发生,提高其使用寿命,对其力学性能、金相组织、硬度、耐蚀性能等进行检测分析。结果表明:已服役连续管金相及硬度分析、HIC、SSCC试验结果均无异常,但是其屈服强度降低明显,远低于设计值,耐中性盐雾腐蚀性能较差。疲劳断口分析结果表明,起裂区存在大量夹杂物,能谱分析主要有O、Si、Al等元素。该连续管在含H2S井中服役后,存在强度下降严重、疲劳断口起裂区有大量夹杂物、腐蚀较严重等问题,在新疆该区块环境下使用有较大风险,应谨慎选择。
Abstract:
The 130ksi steel grade coiled tubing produced by a foreign manufacturer had fracture failure accident when working in a H2S containing well in Xinjiang. In order to prevent and reduce the failure accident of coiled tubing in use and improve its service life, the mechanical properties, metallographic structure, hardness and corrosion resistance of the coiled tubing were tested and analyzed. The results show that the metallographic and hardness analysis, HIC and SSCC test results of the coiled tubing in service are normal. However, the yield strength of the coiled tubing is significantly reduced, much lower than the design value, and its resistance to neutral salt spray corrosion is poor. The fatigue fracture analysis results show that there are a large number of inclusions in the crack initiation zone, and the energy spectrum analysis mainly contains elements such as O, Si, and Al. After the coiled tubing is used in the H2S containing well, there are some problems, such as serious strength decline, a large number of inclusions in the crack initiation area of fatigue fracture, serious corrosion and so on, which is risky to use in Xinjiang, so it should be chosen carefully.
