Experimental Study on Filtration Characteristics of Temperature-controlled Chemical Fracturing Fluid
To investigate the filtration characteristics of temperature-controlled chemical fracturing fluids,a dynamic filtration instrument was employed to analyze the influence of phase change fracturing fluid volume fraction,temperature,filtration pressure difference,and permeability on the filtration process.The results indicate that a lower phase change fracturing fluid volume fraction,higher temperature,greater filtration pressure difference,and higher permeability correspond to an increased filtration coefficient of the chemical fracturing fluid.The phase change fracturing fluid volume fraction has a relatively minor impact,while the filtration pressure difference and permeability have significant effects.Thus,in high-temperature reservoirs,the filtration loss of chemical fracturing fluid can be mitigated by injecting a pre-fluid.Additionally,in high-permeability reservoirs or at high injection rates,certain filtration reduction measures should be implemented to enhance liquid efficiency.
