As one of the important materials for fracturing construction, the quality of proppant is directly related to the effectiveness of fracturing construction and directly affects the later recovery rate. As an important material, fracturing proppant is tested according to SY/T 5108-2014 “Performance Testing Methods for Proppants Used in Hydraulic Fracturing and Gravel Filling Operations”. According to this standard, the testing personnel conduct tests on six indicators such as proppant sieve analysis, apparent density, bulk density, crushing rate, sphericity, and turbidity. To verify the operability of the standard and the repeatability of the results, repeated experiments were conducted between proppant samples, and it was found that the repeatability of the results of some proppant detection items was poor. This article conducted a study on the repeatability of fracturing proppant testing indicators and found that the differences in testing results mainly come from aspects such as equipment accuracy, operating techniques, and sample uniformity. Among them, the differences in visual density, volumetric density, and sphericity results are relatively small; The differences in sieve analysis results mainly come from the uniformity of the sample, the error of the vibrating screen machine, and the uniformity of the sieve mesh; The difference in crushing rate results mainly comes from the uniformity of the sample placement in the crushing chamber; The difference in turbidity mainly comes from the uniformity of the sample, the frequency and amplitude of shaking, and the model of the turbidity meter. Through comparative analysis, this article establishes a set of experimental methods with high repeatability of results based on SY/T 5108-2014 “Performance Testing Methods for Proppants Used in Hydraulic Fracturing and Gravel Filling Operations”, in order to provide reference for institutions and individuals conducting fracturing proppant testing.
