Why can't waste water be discharged when it is acidic

Established in 2001, Puyang Zhong Yuan Restar Petroleum Equipment Co.,Ltd, “RSD” for short, is Henan’s high-tech enterprise with intellectual property advantages and independent legal person qualification. With registered capital of RMB 50 million, the Company has two subsidiaries-Henan Restar Separation Equipment Technology Co., Ltd We are mainly specialized in R&D, production and service of various intelligent separation and control systems in oil&gas drilling,engineering environmental protection and mining industries.We always take the lead in Chinese market shares of drilling fluid shale shaker for many years. Our products have been exported more than 20 countries and always extensively praised by customers. We are Class I network supplier of Sinopec,CNPC and CNOOC and registered supplier of ONGC, OIL India,KOC. High quality and international standard products make us gain many Large-scale drilling fluids recycling systems for Saudi Aramco and Gazprom projects.

More than 99 percent of the ,fracturing fluid, is water and sand, while other components such as lubricants and bactericides constitute the remaining 0.5 percent. This ,fracturing, mixture enters the well bore, and some of it returns as ,flowback, or produced water, carrying with it, in addition to the original materials, dissolved and suspended minerals and other materials that it picks up in the shale [2] .

The main purposes of fracturing fluid are to extend fractures, add lubrication, change gel strength, and to carry proppant into the formation. There are two methods of transporting proppant in the fluid – high-rate and high- viscosity .

Natural gas extracted during ,processing, is further pro- cessed to remove liquids, then compressed and reinfected into the reservoir through service wells. Water is chemically treated and also reinfected into the reservoir. ,Reinjection, of water and natural gas increases oil recovery by maintaining reservoir pressure.

Fracturing flow-back fluid in shale gas mining is usually treated by re-injecting into formation. After treatment, the fracturing flow-back fluid is injected back into the formation. In order to ensure that it will not cause too much damage to the bottom layer, feasibility evaluations of re-injection of two kinds of fracturing fluid with different salinity were researched.
