Water consumption is high and more serious problem is ceramic proppant manufacturers water pollution. First, the fracturing fluid contains additives include drag reducing agents, surfactants, scale inhibitors, clay stabilizers, bactericides, pH adjusting agents, anti-fluid loss additive, demulsifier, benzene, chromium, and sometimes also contain a small amount of radioactive substances such as radium. Therefore, shale gas mining process, we must properly handle the fracturing fluid. In general, the technical and theoretical level, the situation is fracturing fluid contaminated groundwater does not occur, but can not rule out human factors and equipment, resulting in fracturing fluid underground or aboveground storage leak and contaminate groundwater or surface ecology. Second, because shale gas production and storage sites, almost all aquifers located below, and therefore the drilling process, must go through aquifers, if drilling improper easily lead to contamination of groundwater chemical additives used during drilling. ceramic proppant In addition, for example, in the North China Plain, shale gas, since the area of ​​the over-exploitation of groundwater is one of serious, and therefore in some coastal areas because of lower groundwater levels, causing sea reflux, eventually causing ground water pollution is serious.
