摘要:
为了满足含少量硫化氢油气田开发的需求,延长连续管在含硫环境下的使用寿命,研究开发了一种CT80S抗硫连续管产品,并按照相关标准对该产品的组织和性能进行了检测。检测结果显示,CT80S抗硫连续管组织以F(铁素体)+P(珠光体)为主,晶粒度为12级,带状组织为0.5级,夹杂物小于1.0级;管体强度、硬度及塑性指标均满足API SPEC 5ST标准要求,且硬度控制在18HRC以内;样管水压爆破压力140.5 MPa,外压挤毁压力118.9 MPa,疲劳寿命均值1 055次;样管在90%σs应力加载下未发生SSCC断裂;高温高压腐蚀速率仅为1.11 mm/a。试验结果表明,开发的CT80S抗硫连续管对HIC不敏感,且抗硫化氢应力腐蚀性能良好,同时还具有优异的抗内、外压性能及抗低周疲劳性能,满足含硫环境下的使用要求。
Abstract:
In order to meet the needs of the development of a small amount of H2S oil and gas field and prolong the service life of the coiled tubing in a sulfur-containing environment, developed the CT80S anti-sulfur coiled tubing product. The test results show that the structure of CT80S anti-sulfur coiled tubing is F (ferrite) + P (pearlite), the size of grain is 12, the grade of band structure is 0.5, and the grade of inclusion is less than 1.0. The index of strength, hardness and plasticity of pipe body meet the requirements of API SPEC 5ST standard, and the value of hardness is controlled within 18HRC. The water pressure burst pressure of the sample tube is 140.5 MPa, the external pressure is 118.9 MPa, and the average value of fatigue life is 1 055 times. The sample tube did not occurrence SSCC fracture under 90%σs stress loading, and the corrosion rate of sample tube under high temperature and high pressure was only 1.11 mm/a. The test results show that the developed CT80S anti-sulfur coiled tubing is not sensitive to HIC, and has good performance of resistance to hydrogen sulfide stress corrosion. It also has excellent performance of anti-pressure on body internal and external
