Design and Flow Field Optimization Analysis of Dissolution Promoting Tool for Salt Cavern Gas Storage Cavity
In the construction of salt cavern gas storage cavities,there is a lack of parameter optimization process for dissolution promoting tools,and there is no explanation on the relationship between their technical pa-rameters and the size and shape of the formed cavities.An extended rapid dissolution promoting tool for constructing cavity was designed,and the Fluent software was used to simulate the external flow field of the tool to study the effects of nozzle angle,inlet displacement and tool rotation speed on the size and shape of the constructed slotting at the early stage of salt cavern gas storage.The analysis results show that the tool can achieve controllable working state and adaptive extension,and the nozzle can be replaced.The 45° nozzle angle is the optimal slotting angle during the slotting period.The larger the inlet displacement,the greater the jet distance and range of high-speed jet flow are.However,when the inlet displacement exceeds a certain value,the amplitude of the increase in jet distance rapidly decreases.So,it is proposed to use a lower rotation speed during operation of the tool to reduce the kinetic energy loss of a single high-speed jet flow.The conclusions provide theoretical guidance for the field ap-plication of extended rapid dissolution promoting tool of cavities.
