【摘要】：螺桿泵采油系統(tǒng)以其結(jié)構(gòu)簡單、管理方便、適應(yīng)性強等特點日益受到國內(nèi)外油田的重視。隨著三次采油技術(shù)的發(fā)展,螺桿泵采油系統(tǒng)已成為油田中最重要的人工舉升方式之一。目前油田中普遍使用內(nèi)擺線型單螺桿泵,這種螺桿泵螺桿一般為金屬材料,襯套一般為橡膠材料,由于襯套是易損件,檢泵更換襯套時需要將油管和抽油桿同時取出,檢泵時間長,檢泵費用高,與“高水平,高效益”的長遠方針極其不符。外擺線線型從理論上也可用于螺桿泵的設(shè)計,但關(guān)于此方面的研究卻甚少。本文從外擺線型骨線共軛副的形成入手,通過分析外擺線型單螺桿泵螺桿-襯套副的相對運動,發(fā)現(xiàn)外擺線型單螺桿泵的固定接觸點出現(xiàn)在襯套骨線上,從而提出襯套采用金屬材料,螺桿表面采用橡膠材料;用速度瞬心法推導(dǎo)出齒凸接觸點和齒凹接觸點處相對滑動速度的計算公式,并用MATLAB生成了速度曲線;對Solid Works進行二次開發(fā),實現(xiàn)了外擺線型單螺桿泵的參數(shù)化建模,用Solid Works Motion對外擺線型單螺桿泵進行了運動仿真,并提取出了齒凸接觸點和齒凹接觸點處相對滑動速度的離散值,與MATLAB輸出的公式曲線進行對比,擬合度很高,最大偏差率僅為0.14203%;將速度曲線與嚙合狀態(tài)進行對應(yīng),發(fā)現(xiàn)齒凹接觸點處相對滑動速度的最大值發(fā)生在螺桿齒凸中點與襯套齒凹中點相接觸處,齒凸接觸點處相對滑動速度最大值發(fā)生在螺桿齒凸中點與襯套齒凸中點相接觸處。將過流面積、幅長系數(shù)、最大綜合曲率和相對滑動速度作為影響外擺線型單螺桿泵性能的指標,通過線性加權(quán)組合法構(gòu)建優(yōu)化的目標函數(shù),用閥值法對各個子目標進行無量綱化處理,用MATLAB優(yōu)化工具箱中的fmincon函數(shù)進行優(yōu)化計算,全局最優(yōu)解為幅長系數(shù)K=0.757,等距半徑系數(shù)r0=1.4。
[Abstract]:The screw pump oil recovery system has been paid more and more attention by oil fields at home and abroad for its simple structure, convenient management and strong adaptability. With the development of tertiary oil recovery technology, screw pump oil recovery system has become one of the most important artificial lifting methods in oil fields. At present, the inner cycloid type single screw pump is widely used in oil fields. The screw of this kind of screw pump is usually metal material, and the bushing is generally rubber material. Since the bushing is a wearable part, it is necessary to remove the tubing and sucker rod simultaneously when the pump is replacing the bushing. The pump inspection time is long, the pump inspection cost is high, and the long-term policy of "high level, high efficiency" is extremely inconsistent. The cycloid type can also be used in the design of screw pump theoretically, but there is little research on this aspect. Starting from the formation of the conjugate pair of the outer cycloid type bone line, by analyzing the relative motion of the screw bushing pair of the cycloid type single screw pump, it is found that the fixed contact point of the outer cycloid type single screw pump appears on the bushing bone line. The formula of relative sliding velocity between tooth convex contact point and tooth concave contact point is derived by velocity instantaneous center method, and the velocity curve is generated by MATLAB, the metal material is used for bushing and rubber material is used on screw surface, and the relative sliding velocity between tooth convex contact point and tooth concave contact point is derived by velocity instantaneous center method. The parametric modeling of cycloidal single screw pump is realized by the secondary development of Solid Works. The kinematic simulation of the external cycloidal single screw pump with Solid Works Motion is carried out, and the discrete value of the relative sliding velocity between the contact point of tooth convex and the contact point of tooth concave is extracted. Comparing with the formula curve of MATLAB output, the fitting degree is very high, the maximum deviation rate is only 0.14203, the velocity curve is corresponding to the meshing state, It is found that the maximum relative slip velocity at the contact point of tooth concave occurs at the contact point between the middle point of the screw tooth convex and the middle point of the bushing tooth concave, and the maximum value of the relative slip velocity at the contact point of the tooth convex point occurs at the contact point between the middle point of the screw tooth convex and the middle point of the bushing tooth convex. The overcurrent area, amplitude and length coefficient, maximum synthetic curvature and relative sliding velocity are taken as the indexes to influence the performance of cycloidal single-screw pump. The optimized objective function is constructed by linear weighted combination method. The threshold method is used for dimensionless processing of each subtarget, and the fmincon function in MATLAB optimization toolbox is used to optimize the solution. The global optimal solution is amplitude and length coefficient K _ (0.757) and isometric radius coefficient r _ 0 ~ (1. 4).
