潜油电泵机组斜井通过能力与易失效部件研究
|
摘要
本文根据管柱能够靠自身重力下放到井下的四个判别条件:刚度条件、接触条件、强度条件、摩阻力条件和由于潜油电泵机组在斜井内受到井眼曲率变化引起机组发生大变形以及机组下放受到的机械阻力,提出了采用强度条件和摩阻力条件来评价电泵机组斜井通过能力,并建立了潜油电泵机组斜井受力变形分析的三维计算有限元模型。应用ANSYS软件的大变形、接触非线性理论对电泵机组在斜井内的受力进行了分析,计算出WIDD-C17井,130电泵机组,在30°井斜角时能通过的极限曲率为6°/30m,此时下放推力为1.75kN。最后应用ANSYS软件的二次开发功能APDL编制了潜油电泵机组斜井通过能力评价的专用程序,可以根据给定的井眼轨道、电泵机组,模拟计算机组在不同曲率井段内的受力变形状态,图形显示电泵机组复合应力等结果,并重新对机组在不同井眼曲率的通过能力进行了评价。在电泵机组通过斜井段后,由于其潜油电泵轴和泵接头连接螺钉易失效,因此本文对电泵轴和泵接头连接螺钉进行了有限元分析。通过对电泵轴与花键套接触的有限元分析,得到了电泵轴的应力分布情况,泵轴最大应力发生在花键轴与过渡段连接处。泵轴与花键套由不同材料改为相同材料蒙乃尔K-500,花键根部的应力集中系数下降了13.72%;花键轴键侧根部圆弧由外圆弧改为内圆弧设计,花键根部应力集中系数下降了10.77%,为电泵轴花键段的设计和花键套材料的选用提供了依据。针对潜油电泵机组连接螺钉在承受不同扭矩作用时的受力情况,以及对螺钉不同的排列时所能传递扭矩和各螺钉受力情况的分析,得到了潜油电泵泵接头连接螺钉传递扭矩的规律,为判断螺钉的失效和装配提供了理论方法。
This article according to rely on its own gravity into down hole string of four criterion: stiffness, contact, strength, friction conditions and because ESP unit to receive hole the curvature change in the deviated hole to cause the unit to have the mechanical resistance which the big distortion as well as the unit down received, proposed used the intensity condition and friction condition appraises the electric pump unit deviated hole the traffic capacity, and the establishment of an electric submersible pump deviated hole stress deformation analysis by the 3-D finite element model.Using the ANSYS software big distortion, the contact non-linearized theory have carried on the analysis to the electric pump unit's deviated hole stress, calculates the WIDD-C17 well, 130 electric pump units, when Well pass through an angle of 30°can through the limit curvature for 6°/30m, this time the thrust of the decentralization is 1.75kN. Finally established using ANSYS software re-development function APDL has electric submersible pump unit deviated hole the traffic capacity appraisal specific program, might act according to the hole track, the electric pump unit which assigned, might simulation state of the unit in different curvature force deformation, and graphical display the results of electric pump unit compound stress and so on, and has carried on the appraisal to the unit in the different hole curvature the traffic capacity again. In electric pump unit after deviated section, because electric submersible pump axis and the pump joint bolt is extremely easy to expire, therefore this article has carried on the finite element analysis to the electricity pump axis and the pump joint bolt. Through finite element analysis which contacts to the electricity pump axis and the spline set, obtained the electricity pump axis stress distribution situation, spline axis with the maximum stress in the transition of the junction. Pump axis and Spline set into the same materials MonelK-500 from different materials, spline root stress concentration factor dropped 13.72%; Key spline axis adjacent to the root change into the inside circular arc from the outside arc design, spline root stress concentration factor decreased by 10.77%. It has provided the basis for the design of the spline axis and material selection of spline sets. In view of stress situation of the electric submersible pump unit to join the bolt when it is in withstanding different torque function, as well as bolt can transmit the torque and various bolts stress situation analysis when they are different arrangement, obtained the rule of the joint bolt of the electric submersible pump connection transfer torque, for judged the expiration and the unit of the bolt has provided the theory method.
