Calculation of Water Hammer Pressure

Zhang Yingjin1 Zhu Zhongxi1 Cai Min2 Shang Kexin3(1.School of Petroleum Engineering,Yangtze University,Jingzhou,Hubei,434023,China;2.No.9 Oil Production Plant,Daqing Oilfield Co.Ltd.,Daqing,Heilongjiang,163853,China;3.No.7 Oil Production Plant,Daqing Oilfield Co.Ltd.,Daqing,Heilongjiang,163517,China)  
The water hammer pressure in wellbore was analyzed when the drilling pump was opened or closed using transient flow theory.The numerical calculation of water hammer pressure using characteristic curve was introduced in detail,computation examples are presented under initial and boundary conditions.The calculation results indicate that a certain amount of time was needed for the flow rate of drilling pump to increase or decrease to a stabilized value under drilling pump opening or closing.The longer the time the smaller the hammer pressure which is valuable for the field drilling operations.
