【摘要】：可移动连续试油装置是油田开采石油使用的试油排液装置。它是在陆地油井正式安装抽油机之前,通过机械举升的方法将井内液体排出至地面的装置。同样是致力于排液,但是由于试油排液施工时间为十几天到一个月,且井口地面安装条件差,所以各型现场使用的抽油机无法直接使用。早期国内应用最广泛的试油排液装置是以通井机做为动力源,此装置工作效率低、人工劳动强度大,不是试油排液专用设备。因此,本文主要是研制生产出可移动连续试油装置,完成其运动和载荷分析,以及现场实验测试和优化改进。本文基于油田试油排液的工艺要求提出装置的主要设计参数,研发出开关磁阻电机和摆线针轮减速器一起密封于滚筒之内的电动滚筒,完成装置平衡箱、刹车、悬挂系统的选型和结构设计。设计的新装置有储能节能系统能耗低、对作业场地条件要求低、搬迁安装方便、能实现自动连续试油排液。参考目前主要类型抽油机的运动学、静力学理论对可移动连续试油装置悬点的运动和载荷变化规律进行理论分析,其中重点对悬点的加速度和载荷进行详尽的分析,并进行实例计算。分析结果表明,此装置的运动对机架产生的冲击载荷小,装置在低冲次下运行更平稳。采用有限元分析软件对可移动连续试油装置进行强度校核和结构优化,以及分析12根绷绳的弹性模量对装置影响。分析可知,选用弹性模量较大的绷绳时,装置能更好的满足使用要求。在满足强度要求和使用功能的前提下,经结构优化后机架主支架截面积降低32.1%,总高降低38.9%。对在油田使用中的可移动连续试油装置的悬点加速度和载荷进行现场测试。测试值和理论计算值相差不大,说明本论文中悬点的理论分析可以用来初略估算可移动连续试油装置悬点的加速度和载荷,可对此类装置的悬点分析提供一定的理论参考。
[Abstract]:Movable continuous oil test device is a kind of oil test and drainage device used in oil field production. It is a device to discharge liquid from the well to the ground by mechanical lifting before the pumping unit is officially installed in the land oil well. It is also devoted to drainage, but because the construction time of oil test drainage is more than ten days to a month, and the installation conditions of wellhead surface are poor, the pumping units used in various types of field can not be used directly. In the early stage, the most widely used oil test and drainage device in China is to use the well rig as the power source, which has low working efficiency and high labor intensity, so it is not a special equipment for oil test and drainage. Therefore, this paper mainly develops and produces a movable continuous oil test device, completes its motion and load analysis, as well as field test and optimization improvement. In this paper, based on the technological requirements of oil field test and drainage, the main design parameters of the device are put forward, and the electric drum sealed in the drum with the cycloid needle wheel reducer is developed, and the type selection and structure design of the balance box, brake and suspension system of the device are completed. The designed new device has the advantages of low energy consumption of energy storage and energy saving system, low requirements for working site conditions, convenient relocation and installation, and can realize automatic continuous oil test and drainage. Referring to the kinematics and statics theory of the main types of pumping units at present, the movement and load variation of the suspension point of the movable continuous oil test device are analyzed theoretically, in which the acceleration and load of the suspension point are analyzed in detail, and an example calculation is carried out. The analysis results show that the impact load of the device on the frame is small, and the device runs more smoothly at low impact. The strength check and structure optimization of movable continuous oil test device are carried out by finite element analysis software, and the influence of elastic modulus of 12 bandages on the device is analyzed. The analysis shows that the device can better meet the requirements when the bandage with large elastic modulus is selected. On the premise of meeting the strength requirements and using function, the cross section area of the main support of the frame is reduced by 32.1% and the total height is reduced by 38.9% after structural optimization. The suspension acceleration and load of movable continuous oil test device used in oil field are tested on the spot. There is no significant difference between the test value and the theoretical calculation value, which shows that the theoretical analysis of the suspension point in this paper can be used to estimate the acceleration and load of the suspension point of the movable continuous oil test device, and can provide some theoretical reference for the suspension point analysis of this kind of device.
