Software Development And Mechannics Analysis For Testing Pipeline In Highly Deviated Wells

Indeed in an increasing number of fields, throughout the world, the production of hydrocarbons is performed exclusively through highly deviated wells. Highly deviated wells has the characteristic of long horizontal interval, high angle and long deflection reducing open well bores. During working and producing, the tube string bear the internal pressure, external pressure, drilling weight in the well bottom, tubing string weight, viscous force of fluid, etc. During the pipeline running, the line may become sinusoidal or spiral bending. The scholar in the world, do many research work in the working station of the pipeline. Based on all the study, using finite element method, this paper analysis the tubing string, and construct a mechanics and mathematical model .The strength verifying and distortion analysing of the tubing string is a complex and sever work.. This paper present a computer programme which can be used to calculate the strength, analyze the distortion and simulation the running process of the tubing string.
