【摘要】：潜油螺杆泵采油系统能够抽汲稠油及气、液、固三项混合液，且具有出油连续、平稳，不易砂卡、气锁等独特优势，对于稠油、含气、含砂油的开采具有重要作用，在国内外各油田的开采作业中得到广泛应用，并取得了良好发展前景和经济效益。为适应潜油螺杆泵机组低速运转的要求，减速器问题成为研究潜油螺杆泵采油系统性能的关键。由于潜油螺杆泵减速器的传动比取值范围受到减速器外径尺寸的影响，，先前的研究方法计算出潜油行星减速器传动比取值范围尚不完善，因此本文在明确了潜油行星减速器的功能和性能需求的基础上，针对潜油减速器运行的恶劣环境和苛刻的径向尺寸限制，引入TRIZ理论为传动比取值范围的计算提供方法和工具，创新性的利用发明创造原理解决取值范围求解问题。本文首先介绍了潜油螺杆泵采油系统及其减速器的国内外发展和TRIZ理论的国内外发展情况，对潜油行星减速器的功能和性能需求及结构设计进行了分析，进而根据TRIZ理论的物—场关系模型创建了潜油行星减速器的物—场模型。在此基础上，利用计算机辅助创新软件建立了潜油行星减速器矛盾冲突矩阵，对系统中的冲突参数进行标准化定义，运用矛盾矩阵系统找寻对应的发明原理，根据原理的启示对潜油螺杆泵减速器的传动比取值范围进行计算。通过行星齿轮的传动条件得到了单级减速器传动比的上限值，运用图解法确定了传动比的下限值，经分析计算最终得到了潜油行星减速器在实际运行中传动比的合理取值范围，计算结果论证了TRIZ理论的可行性和有效性，为确定潜油螺杆泵减速器传动比的取值范围提供了全新的思维方式，对工程项目的实施有重要的理论指导意义。
[Abstract]:The oil recovery system of submersible screw pump is capable of swabbing heavy oil and its mixture of gas, liquid and solid, and has the unique advantages of continuous, stable oil production, not easy to sand card, gas lock, etc., which plays an important role in the production of heavy oil, gas bearing oil and sand containing oil. In order to meet the requirements of low speed operation of submersible screw pump unit, it has been widely used in various oil fields at home and abroad, and has obtained good development prospects and economic benefits. The problem of reducer becomes the key to study the performance of submersible screw pump oil recovery system. Because the transmission ratio of submersible screw pump reducer is affected by the diameter of reducer, The previous research method shows that the range of transmission ratio of submersible planetary reducer is not perfect, so this paper makes clear the function and performance requirement of submersible planetary reducer. In view of the harsh environment and harsh radial size restriction of submersible reducer, TRIZ theory is introduced to provide methods and tools for calculating the range of transmission ratio, and innovative use of the principle of invention and creation is used to solve the problem of calculating the value range. This paper first introduces the development of submersible screw pump oil recovery system and its reducer at home and abroad and the development of TRIZ theory at home and abroad, and analyzes the function, performance requirements and structural design of submersible planetary reducer. Based on the object-field relation model of TRIZ theory, the object-field model of submersible planetary reducer is established. On this basis, the conflict matrix of submersible planetary reducer is established by computer aided innovation software. The conflict parameters in the system are defined standardized, and the corresponding invention principle is found by using the contradiction matrix system. According to the inspiration of principle, the range of transmission ratio of submersible screw pump reducer is calculated. The upper limit value of transmission ratio of single stage reducer is obtained by the transmission condition of planetary gear, and the lower limit value of transmission ratio is determined by graphic method. Through analysis and calculation, the reasonable range of transmission ratio of submersible planetary reducer in actual operation is obtained. The calculation results demonstrate the feasibility and validity of TRIZ theory. It provides a new mode of thinking for determining the range of transmission ratio of submersible screw pump reducer, and has important theoretical guiding significance for the implementation of engineering projects.
