Abstract: Hydraulic fracturing is one of the most effective technology for increasing production of uncoventional reservoirs. Turbidity is a key technical property for proppant evaluation. However，the current standard test method in China is different from the international test method，which impacts proppant optimization in hydraulic fracturing treatments in China. In order to improve proppant testing proficiency in China，this paper systematically investigates the influences of the procedures of sampling and sample preparation，liquid sampling position，and turbidity meter on the test value of turbidity. Moreover，considering the physical and chemical properties of suspended particles that affect proppant turbidity，the effects of turbidity on fracture conductivity and reservoir damage are studied. The influencing factors on conductivity and permeability during turbidity testing have been proposed.These studies have important implications for understanding proppant turbidity and proppant optimization and help to reduce costs for proppant manufacturers.
