摘要
API偏梯形螺纹套管内外螺纹机紧联接时 ,采用控制接箍端面与管体上三角形上螺纹标记之间相对位置的方式进行上螺纹。长期以来 ,从事石油工程的技术人员对此的理解和做法不统一。文章通过对相关标准、资料的对比分析研究 ,找出了疑点所在 。
When power-tight API trapezoidal threaded casing, the adoption of using triangle marking on casing as relative position to tight casing is a long practice in oilfield. The understanding and practical operation differ from technician and crew workers. The paper presents the analysis and comparison on relative code, information and the misunderstanding to unify their comprehension.
