摘要

概述了国内外硫化物应力腐蚀开裂(SSC)试验的相关标准及推荐方法的评定指标,结合油气井SSC风险分布、井下油套管的受力情况与抗SSC性能检测的目的,选取了标准拉伸试验法(NACE TM 0177中的A法)作为抗硫油套管抗SSC性能的检测方法,并给出了详细的结果评定方法。以110TS套管为例,利用标准拉伸试验法对其抗SSC性能进行了检测。结果表明:通过标准拉伸法可有效地检测出抗SSC性能不达标的油套管,避免其流入后续的生产环节,引发生产与安全事故。

Abstract

In this paper, the standards and evaluation index of sulfide stress cracking(SSC)testing at home and abroad were summarized.Method A in NACE TM 0177 standard was selected as the test method for SSC-resistant casing and tubing according to the SSC risk distribution of oil and gas wells, the stress situations of casing and tubing and the purpose of SSC-resistent performance test.The result evaluation method was introduced in detail.Taking 110TS casing as an example, its SSC resistance was tested by using the standard tensile test.Results showed that the standard tensile test could effectively detect the SSC resistance to find out the unqualified substandard oil casing and tubing further for avoiding its flow into the subsequent production process resulting in safety accidents.
