Stress Analysis Of The Oil Casing Electromagnetic Shaping Process

In the development of discover the oil field, as a result of the infection of movement of lithosphere and the effusion tap and other factors, the oil and water well. drive pipe can have each kind of distortion shape. This article introduced the sleeves of the damage to the mechanism and the deformation, and a series of restoration techniques and detection techniques are developed for treatment of casing damage well after decades of research at home and abroad. For further improves the repair of wells quality and the reduction repair of wells time. The article has the idea of electromagnetic plastic, has carried on the mechanical analysis and the structure optimization, the result will be the direction of the amelioration for plastic tools.This article is to analyze the process of casing electromagnetic force shaping process. This process is mainly shaper cone interaction and deformation of the casing. Through the shaper in the coil the electromagnetic force generated mutually exclusive, so cone movement downward, forcing the expansion sleeve opening deformation. Therefore, the stress analysis of tapered head design cone model on the impact of the various critical mechanical quantity.Union the structure of electromagnetic shaper, carries on the stress analysis to the shaper, has established the mechanical equation and torques balance equation. Through analysis to mechanical balance equation and torques balance equation, using the MATLAB software, shows the mechanical quantities and the variation of cone head parameter curve, analyzed and discussed within the cone angle and cone angle and the outer casing and cone deformation action point of each volume of the mechanical. Based on the mechanical quantities we request parameters to determine the scope of each cone to ensure that repair different variable casing. Choose the right of the shaper to repair the different variable casing, achieved the requirements of the reshaping, and has proved the rationality and feasibility of the result of analysis.
