The Extraction Methods Research Of Geochemical Parameter Of Groundwater In Qingshen After Fracturing

The real parameter of groundwater is very important in prospecting and investigating. The effect of fracturing fluid to the verity parameter of groundwater hasn't been researched long time.Some internal scholars has researched the process of flowback with the method of tracer, basis the tracer dosage and bulk, ascertain status of flowback. During the process of flowback, the verity parameter of each hydronium and the variety rules of each hydronium at any time are difficult to acquire. Some questions like these haven't been settled now.By the analysis and test of the five fractured wells'samples, the change current of each hydronium, Mathematical physics model was based to deoxidize the method of groundwater in Xujiaweizi. Equation with little parameter and hight-point was chosen to fit the original chroma numerical value of target wells in data-base. The chroma value when the time tends towards to∞was the real parameter of the hydronium in groundwater. The method was based to deoxidize the chemical characters. By the analysis of the anciently samples, make the use of the method to beg the verity values of each hydronium, pick-up the index of the original values, based the data-base of analysis on water in Xujiaweizi fault.
