【摘要】：随着石油勘探和开发程度的深入,稠油油藏的开采在石油开采中的地位变得愈加重要,目前对于储量极大的超稠油油藏以及沥青质油藏,常规热采技术难以取得好的成效,蒸汽辅助重力泄油能成功的解决这一问题。在蒸汽辅助重力采油中,潜油电泵起着重要作用,潜油电机作为潜油电泵机组的动力部分,是保障整个机组正常运转的关键,其性能直接影响整个电泵机组的质量和寿命。潜油电机工作于油井下数千米的地方,影响其运行可靠性的因素有很多,但起主要作用的是电机工作时的发热引起的温升问题。本文主要设计了能够在高温环境中工作的潜油电机并对不同环境下的温度场进行了计算。本文对下面几方面内容进行了分析研究:首先,对潜油电机的应用背景和作用作了介绍,介绍了潜油电机的基本结构及其特点;对国内外不同类型的潜油电机及高温电机关键技术的研究现状进行了详细叙述。分别设计了电机的主要尺寸、电磁负荷等参数,研究了高温环境对电机电磁材料性能的影响,建立了电机的二维模型,并通过有限元软件的电磁计算结果验证了电机各项参数设计的合理性。其次,通过有限元及解析计算,得到潜油电机各部位的损耗,主要为机械损耗,铜耗,定子铁心齿部、轭部损耗。在确定了边界及初始条件后,建立了潜油电机的三维热模型,对其剖分并进行了流体场设置,通过三维有限元软件仿真了常态情况下潜油电机的各部位温度分布及温升,验证了设计的潜油电机的耐高温性能。最后,分析了潜油电机在不同工作环境下的温升分布,并对其进行分析,为实际工况提供了参考意见;同时对所设计的潜油电机进行了温升实验及现场测试,得到的结果与仿真实验进行了对比,验证了设计电机与仿真实验的正确性。
[Abstract]:With the deepening of petroleum exploration and development, the status of heavy oil reservoir production becomes more and more important. At present, it is difficult to obtain good results by conventional thermal recovery technology for ultra-heavy oil reservoirs and asphaltene reservoirs with huge reserves. In steam assisted gravity oil recovery, submersible oil pump plays an important role. As the power part of submersible pump unit, submersible motor is the key to ensure the normal operation of the whole unit. Its performance directly affects the quality and life of the whole electric pump unit. The submersible motor works thousands of meters under the well, and there are many factors affecting its reliability. In this paper, the submersible motor which can work in high temperature environment is designed and the temperature field in different environment is calculated. Surface content is analyzed and studied: first of all, The application background and function of submersible motor are introduced. The basic structure and characteristics of submersible motor are introduced. The research status of the key technologies of submersible motor and high temperature motor at home and abroad is described in detail. The main dimensions and electromagnetic load parameters of the motor are designed, and the influence of high temperature environment on the electromagnetic material performance of the motor is studied. The two-dimensional model of the motor is established, and the rationality of the design of the motor parameters is verified by the electromagnetic calculation results of the finite element software. Secondly, through the finite element and analytical calculation, the loss of the submersible motor is obtained, which is mainly mechanical loss. After determining the boundary and initial conditions, the three-dimensional thermal model of submersible motor is established, and the fluid field is set up. The temperature distribution and temperature rise of the submersible motor under normal condition are simulated by 3D finite element software, and the high temperature resistance performance of the designed submersible motor is verified. Finally, the temperature rise distribution of the submersible motor under different working conditions is analyzed. At the same time, the temperature rise experiment and field test of the designed submersible motor are carried out, and the results are compared with the simulation experiment. The correctness of the motor design and simulation experiment is verified.
