摘要：According to the research on fracturing construction mechanism and construction technology of domestic hydraulic fracturing construction site, a real-time optimization model of oil layer hydraulic fracturing using multivariate nonlinear regression is proposed. Firstly, based on the hydraulic fracturing construction mechanism, construction technology, seam-forming mechanism and supporting hardware equipment, key research was carried out. Then, according to various key problems existing at the time of fracturing construction, combined with multivariate nonlinear regression analysis. The multivariate nonlinear regression method based on polynomial function model is further optimized as the core algorithm of the fracturing optimization analysis model. Finally, based on the actual implementation scheme of Wei 319 well, a comparative experiment is designed. The experimental results show that the proposed optimization model based on polynomial function model multivariate nonlinear regression achieves the best prediction accuracy under the same experimental conditions. The model has high precision and adaptability.
