摘要: 关井水击压力的大小直接决定了现场是采用“软关井”还是“硬关井”方式关井。通过对该问题的研究,认为无论采用何种方式关井,其求解过程相似,只是初始条件有变化。在描述关井时一阶拟线形偏微分方程组的基础上,提出采用LW有限差分法进行求解具有可行性和收敛性,并编制了相应的计算机程序。研究表明该方法适用于“软” 、“硬”关井的水击压力计算,具有工程指导意义。

Abstract: The theoretical study was made of the effect of shut-in procedure on the water hammer pressure pulse. According to this problem, the solutions for different shut-in procedures are similar except for the initial conditions. This paper described a series of one factor stimulant linear partial differential equations, LW method for solution and develops relevant computer programs was presented. It is proved that the solutions were appropriate for “soft” or “hard” shut-in.

Key words: water hammer pressure, shut in, partial differential equation
