| 摘 要： | 本文从求解梁挠度的二阶差分方程出发，通过Z变换，最后推导出计算挠度和转角的简单公式，使计算过程简化。对于变截面梁和复杂受载下，此法尤为简便。同时，这也是处理离散参数的数学方法—Z变换在力学中应用的初步尝试。

| Abstract: | According to the actual cases of the low system efficiency of pump unit and under the actual exploitation conditions in Kelamayi Oilfield, the mathematical models of intermittent pumping well was established in the paper. The models include the parameters of the reservoir inflowing, annular testing, andpump unit optimizing system, as well as the whole system hardware configuration. It improved the computer management and real - time monitor, and presented an informative approach to improve the system efficiency. It also provides a guidance meaning for exploiting low permeability and production oilfield. |
