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.
