摘要

摘要: 研究某热采井用110H钢级套管材料在不同温度下的拉伸性能。试验温度选用相关标准推荐的180，240，290，325，350℃，另增加室温拉伸试验。试验结果表明：随着温度升高，该110H钢级热采井用套管材料的屈服强度、抗拉强度均呈下降趋势，且屈服强度对温度更加敏感，下降程度满足相关标准要求；弹性模量随着温度升高也呈下降趋势。对试验结果进行拟合，拟合可信度较高，可用于套管柱设计和选材时参考使用。

Abstract: The tensile properties of 110H steel for the casing as used in a certain thermal recovery well are tested at different temperatures.The test temperatures are selected from those as recommended under applicable specification i.e., 180, 240, 290, 325, 350 ℃, and the room-temperature tensile test is added.The test results show that along with the increase of the temperature, both the yield strength and the tensile strength of the said steel decrease, and the yield strength becomes more sensitive to the temperature.The decrease degree meets the requirement as specified under the applicable specification.Likely the elastic modulus also decreases with increasing of the temperature.The results of the above mentioned tests are fitted, and the fitting reliability is rather high, which is worth referring for design and selection of the casing string.
