Abstract

The invention discloses an underground reservoir capacity measuring method based on gas-liquid diffusion concentration. The method comprises the steps of measuring the volume of an existing water body of an underground reservoir and measuring the volume of a cavity of the underground reservoir. Pre-selected gas and liquid are input into corresponding arrangement throwing points through throwing channels, the gas-liquid concentration measured in real time is transmitted to a computer system through a transmission line by means of liquid and gas concentration sensors, the system carries out operation solution on gas-liquid concentration data matched with time and space information, the volume of the existing water body of the underground reservoir and the volume of the cavity of the underground reservoir are obtained, and the volumes are added to obtain the capacity of the underground reservoir. The underground reservoir capacity measuring method provided by the invention has the advantages of being convenient to operate, low in cost, capable of monitoring the existing water storage amount and the internal environment of the reservoir in real time and the like.

Description

technical field [0001] The invention relates to the technical field of reservoir capacity measurement, in particular to a method for measuring underground reservoir capacity based on gas-liquid diffusion concentration. Background technique [0002] Underground reservoir is an alternative and supplementary water resource regulation and storage method proposed to solve the shortcomings of surface reservoirs, such as large evaporation, short water storage period, and large occupied area. The role of underground reservoirs is to adjust the spatial and temporal distribution of water resources for human use, artificially store surface surplus water in underground water storage structures during high water seasons or when water consumption is low, and change the spatial distribution of water resources; The storage capacity should be used in the dry season, which adjusts the time distribution of water resources. China is also vigorously promoting the use of underground space to bui...
