Abstract:

石油钻具特别是钻杆的现场快速检测一直是该行业所进一步期待的技术,以便更能节省时间减少工人劳动强度及成本,提高经济效益。首先分析了多类型缺陷的漏磁检测原理及现场钻杆快速检测问题,然后进一步地针对现场钻杆料架的堆放方式,在已有固定式钻杆检测设备和移动式钻杆检测装置的基础上,提出了现场钻杆原地整体磁化多杆并行的漏磁检测方法,并通过建模仿真计算进行了讨论与分析证明了其可行性,该方法直接在料架上对多根钻杆进行同时磁化检测,无需钻杆的大空间距离移动,减少了操作程序及劳动强度,节省了检测时间及检测成本,具有一定的优越性。

Oil drilling tools especially for the fast field detection of drill pipe are always the expected technique in relevant industries, which can further save the working time, labour intensity of workmen as well as the cost and thereby improve economic effectiveness. This paper analysed the MFL testing principles for various kinds of defects and the problems regarding to the fast speed field drilling pipes firstly, and then aiming at the stacking mode, proposed a method of MFL testing for multi field drilling pipes by overall magnetization concurrently on the basis of existing fixed and mobile detection device. Discussion is conducted and feasibility is confirmed by modeling and simulation. According to the proposed method, multi-drilling pipes are magnetized and detected simultaneously on the shelf directly without needing to move the drilling tools in large space distance, which decreased the operation process and labor intensity tremendously as well as saved the detection time and cost with superiority to some extent.
