【 摘 要 】

Because of the complex environment of high temperature, high pressure in the well, the deformation, the tilt and the vibration of the tube in the process of uprooted and insert pipe string by snubbing operation device of the oil-gas field, the present coupling alarm device has high false alarm rate. According to the mathematical principle of 3 points determined a circle and collecting information by analogy proximity sensors, the position of tube at the detection surface is determined. The fuzzy algorithm is used to distinguish the diameter of the detection surface which is pipe diameter or coupling diameter, so as to realize the intelligent alarm of the coupling. In this paper, the configuration design of coupling alarm device that includes information acquisition, processing, control and other parts is designed by WinCC flexible software. In addition, the data of detection and calculation is displayed on the monitoring screen in real time and accurately. Experimental simulations verified the intelligent alarm method can accurately collect distance information, identify the position of the coupling and visualize the relevant data.
