| Abstract: | Bio-enzyme is a fracturing fluid gel breaking with good effect of environmental protection.Substrate concentration,enzyme dosage,PH value and temperature are the main factors having influence on fracturing fluid gel breaking.This paper,through orthogonal test,analyzes the impact of various factors on the enzyme fracturing fluid gel breaking,and also the impact of different levels of each factor on the viscosity of fracturing fluid.The results show that different kinds of fracturing fluid viscosity and gel b... |
