摘要
近年世界各高压油气深井中普遍使用VAM、2SC、3SB、NS等系列特殊丝扣套管及油管。本文从世界开发油、套管产品的动向简介了特珠丝扣的结构原理,除部析3SB和VAM两种特殊丝扣的优越性以外,并列表对比了6种特殊丝扣的主要性能。又对如何选择、检验、使用等方面提出了具体意见。
In recent years, the casing and tubing series with special thread such as VAM, 2SC, 3SB, NS, etc., have been widespreadly used in various deep oil-gas wells with high pressure in the world. In this paper, from the world trend in developing casing and tubing products, the textural principle of special thread is briefly introduced. Besides analyzing the advantages of SB and VAM special thieads, the main properties of six types of special thread are compared through tabulating, and the concrete opinions on choice, inspection and use, etc. are proposed also.
