摘要

Due to cost considerations, quartz sand has commonly replaced ceramic proppant in the field. The significant crushing of quartz sand raises concerns about its ability to meet the demands of the fracture network conductivity. Therefore, it is crucial to study the crushing characters of quartz Sand. For faster analysis crushing, a new image processing-based quantitative method is developed to determine the compression proppant crushing rate. Compared with conventional screening methods to verify accuracy. The influence of factors such as sand concentration, particle size combination, and placement method on the proppant crushing rate was analyzed. The results of this analysis were consistent with previous studies, which further confirming the applicability of the proposed method. This research provides a theoretical foundation for hydraulic fracturing and optimization of sand placement in order to maintain long-term high conductivity in fractures.
