摘要
随着油气井开采难度的不断加大和井下环境的日趋恶劣,普通套管已难以满足高抗挤井况的需求,国内企业相继开发出系列高抗挤套管产品。介绍了国内对套管破坏机理、制造工艺、力学性能以及相关标准的研究现状,并对国内生产的现状进行了论述。同时针对国内制造的高抗挤套管、抗挤抗硫套管以及抗挤耐热套管,从抗挤机理、生产工艺、试验研究和标准制定4个方面入手进行了介绍,对比了各企业产品的性能,并对高抗挤套管的发展方向进行了展望。
As the exploitation difficulties of oil and gas wells increasing and underground environments become increasingly severe, it’s difficult for ordinary casings to meet the demands of high collapse resistance, domestic enterprises developed a series of high collapse casing products. In this article, it introduced casing failure mechanism, manufacturing process, mechanical performance and research status of relevant standards, also expounded domestic production status. At the same time, it emphatically introduced domestic high collapse resistance casing, collapse-resistance and sulfur-resistance casing, collapse-resistance and heat resistant casing from 4 aspects, including extrusion mechanism, production process, experimental study and standard establishment. Compared the performance of the enterprise products, and the development direction of high collapse casing was prospected.
