【摘要】：當今世界,石油仍是經(jīng)濟發(fā)展的支柱能源。隨著油田開采速度的加快,我國各大油田的主要油區(qū)已處于高含水開采階段,油井深度不斷增大,抽油機懸點載荷也越來越大,造成油面的高度和填充率的不斷變化。在這種工況下,目前廣泛應用的游梁抽油機由于其固有結構的限制,往往會產(chǎn)生空抽和液擊現(xiàn)象,會大大降低開采效率并降低設備壽命,且其平衡效果差,能耗高的缺點也日益凸顯。因此,現(xiàn)階段對抽油機的基本要求是沖程長,沖程沖次易于調(diào)節(jié),且能耗低。無游梁滾筒式抽油機以其易于實現(xiàn)上述功能而備受重視,但由于缺乏可靠的調(diào)速換向機構,目前滾筒抽油機的應用并不廣泛。本文旨在為滾筒抽油機研制出一種具有可靠性高、能耗低、沖程沖次易于調(diào)節(jié)、自動化程度高的調(diào)速換向裝置——差動調(diào)速換向裝置,為長沖程抽油機的推廣和應用提供保障。首先,設計差動調(diào)速換向裝置的總體方案,規(guī)劃懸點運動規(guī)律并詳細地驗證了其效率。其次,分析抽油機的懸點載荷,確定構件受力及配重(編寫了MATLAB求解程序,對不同采油工況,只需輸入相應參數(shù)即可得出對應的配重大小),并在此基礎上對差動調(diào)速換向裝置的機械部分——調(diào)速部分、換向部分、工作部分——進行了具體的結構設計。隨后,建立整個裝置的三維模型來檢驗其裝配干涉,使用ADAMS虛擬樣機技術對其進行運動學與動力學分析,并用有限元方法驗證了關鍵零部件件的強度。最后,設計了差動調(diào)速換向裝置的電氣控制系統(tǒng)。當該裝置用于不同油井或采油工況(沖程和沖次)改變時,只需根據(jù)工況規(guī)劃出新的運動規(guī)律,重新設定PLC控制程序參數(shù)即可,而不需要做其他調(diào)整,非常方便經(jīng)濟。選用這種差動調(diào)速換向裝置的滾筒抽油機可應用于大多數(shù)油井和多種采油工況,能夠大規(guī)模推廣使用。本文研制的滾筒抽油機差動調(diào)速換向裝置解決了制約滾筒抽油機推廣的換向、調(diào)速問題,為滾筒抽油機的推廣打下了堅實的基礎。
[Abstract]:In today's world, oil is still the mainstay of economic development. With the rapid development of oil fields, the main oil fields in China have been in the stage of high water cut, the depth of oil wells is increasing, and the load of pumping units is increasing, which results in the constant change of oil level height and filling rate. Under this condition, because of the limitation of its inherent structure, the widely used beam pumping unit often produces the phenomenon of air pumping and liquid shock, which will greatly reduce the mining efficiency and the equipment life, and its balance effect is poor. The drawback of high energy consumption is also increasingly prominent. Therefore, the basic requirements for pumping units at present are long stroke, easy to adjust stroke times, and low energy consumption. The non-beam roller pumping unit is paid more attention to because it is easy to realize the above functions. However, due to the lack of reliable speed regulating and reversing mechanism, the drum pumping unit is not widely used at present. The purpose of this paper is to develop a speed regulating reversing device with high reliability, low energy consumption, easy adjustment of stroke times and high degree of automation for roller pumping units, which provides a guarantee for the popularization and application of long stroke pumping units. Firstly, the general scheme of the differential speed regulating commutator is designed, and the law of suspension motion is planned and its efficiency is verified in detail. Secondly, the suspension load of the pumping unit is analyzed, and the load and counterweight of the components are determined. (a MATLAB solution program is written for different oil recovery conditions. On the basis of this, the mechanical part, the commutating part and the working part of the differential speed regulating commutator are designed concretely. Then, the 3D model of the whole device is built to test the assembly interference, and the kinematics and dynamics of the device are analyzed by using ADAMS virtual prototyping technology. The strength of the key parts is verified by finite element method. Finally, the electric control system of the differential speed regulating and reversing device is designed. When the device is used in different oil wells or oil recovery conditions (stroke and stroke), it is only necessary to plan out the new motion rules according to the working conditions and reset the parameters of the PLC control program without any other adjustment, which is very convenient and economical. The roller pumping unit with this kind of differential speed regulating and reversing device can be used in most oil wells and various oil production conditions, and can be widely used in a large scale. The differential speed regulating and reversing device developed in this paper solves the problem of reversing and regulating speed which restricts the popularization of the roller pumping unit and lays a solid foundation for the popularization of the roller pumping unit.
