Abstract

The invention provides an intelligent groundwater monitoring system and method for shale gas development, and the system comprises groundwater monitoring equipment and background monitoring equipment,wherein the groundwater monitoring equipment is integrated with a water level sensor, a PH value sensor, a conductivity sensor and a degree of mineralization sensor; the groundwater monitoring equipment is configured to collect the water level, PH value, conductivity and degree of mineralization of the groundwater in a shale gas development area, and transmit the data to the background monitoringequipment; and the background monitoring equipment is configured to obtain a water quality pollution probability curve by fitting according to the historical key index parameters, historical production information, historical groundwater water quality pollution accident information, key index parameters of groundwater and the current working condition information, and analyze the water quality pollution condition of groundwater according to the water quality pollution probability curve. The groundwater monitoring equipment adopted by the solution is integrated with the water level sensor, thePH value sensor, the conductivity sensor and the degree of mineralization sensor, and solves the technical defect of single parameter of the existing groundwater monitoring equipment.

Description

Technical field [0001] The invention relates to the technical field of evaluation of groundwater environmental factors for shale gas development, in particular to a shale gas development groundwater intelligent monitoring system and method. Background technique [0002] Shale gas is a kind of free, adsorbed or dissolved shale, argillaceous siltstone, argillaceous siltstone, and sandstone intercalation system that are rich in dark organic matter and extremely low porosity and permeability. Unconventional natural gas has the characteristics of self-generation, self-storage and continuous accumulation. [0003] The development of shale gas mainly focuses on the consumption of local water resources during mining, and the impact of drilling fluid, fracturing fluid, flowback fluid, reinjection fluid and deep salt brine on shallow groundwater and surface water. It is mainly reflected in four aspects. One is the large consumption of local water resources by fracturing; the second is gas f...
