Abstract: In order to study the phenomenon and regular movementpattern of liquid flow in annular space in projects such as oil extraction and drilling,the water hammer problem of liquid flow in annular space,which was rarely addressed at the moment,was discussed. According to the structure characteristics of annular space and the motion characteristics of fluid,the calculating formula of water-hammer wave speed was deduced in annular space.The calculating method of friction drag and its effect on the wave speed equations were discussed. The obtained water-hammer wave speed equations could provide reference for the further research of mobility pattern and characteristics of liquid flow in annular space.
