套管螺纹紧密距的测量

Measurement of Thread Standoff of Oil Casing

对用多只螺纹工作量规测量同一石油套管螺纹紧密距值存在一定离散性的问题进行了分析与研究,找出了引起离散性的各种因素。消除各种引起离散性的因素,不仅可提高螺纹工作量规间的互换性、测量套管螺纹紧密距值的准确性和一致性,确保产品质量,还可提高企业的经济效益。

A study is made on the problem that in case of measuring the thread standoff of one given piece of oil casing with more than one working gauges, there exists certain dispersion. Causes responsible for the said dispersion are identified. Getting these causes eliminated will not only enhance the exchangeability of the working gauges, improve the measurement accuracy and consistency of casing thread standoff and ensure product quality, but also increase economic benefit of the manufacturer.
