石油钻井工程中,涡轮钻具已发展成为重要的井下动力钻具之一,使用它不仅可以解决定向井和丛式井开发的需要,而且在普通的直井中同样可以达到提高机械钻速、降低钻井成本的目的。在涡轮钻具的设计中,由于受井眼尺寸的限制,只能采用轴流式涡轮,而对涡轮副叶栅叶形的设计,传统的方法是试凑法,这样就需要较长时间的运算和绘图工作,且最后确定的叶形和计算结果也往往不是最佳的。本文详细地论述了涡轮叶栅的设计理论,并采用计算机编程的方法,根据设计给定的基本参数就可以优选出所需要的叶形数据,并通过打印机或自动绘图机输出叶形截面图。这样,就可以节省大量耗时的手工设计计算及绘图工作。
In the oil drilling project, the turbine drill has become one of the most important downhole power tools. It can not only solve the need of directional and cluster well development, but also improve the penetration rate and reduce The purpose of drilling costs. In the design of turbo drilling tools, axial flow turbines can only be used due to the limitation of the borehole size. However, the conventional design of the turbine leaflet cascade design is a trial and error method, which requires a long time Computing and drawing work, and the final determination of leaf shape and calculation results are often not the best. In this paper, the design theory of turbine cascade is discussed in detail, and the computer programming method is used to select the required leaf shape data according to the given basic parameters of the design. The leaf shape of the blade is output by a printer or automatic plotter. In this way, you can save a lot of time-consuming manual design calculations and drawings.
