Background In the development process of unconventional oil and gas fields, the spreading effect of propping agents directly influences the diversion capability of cracks and the fracturing transformation effect. However, current proppant placement designs rely primarily on experience and limited experimental data, lacking accurate predictive tools. In the prior art, three schemes are mainly adopted for proppant placement design (1) a large-scale proppant parallel plate placement experiment. The migration process of proppants in the fracture was simulated by physical experiments. Common simulation devices include flow cell experiments and fracture model experiments. These experiments can help to study the settling, laying and other behaviors of propping agents, but are subject to experimental conditions, high in cost, long in time consumption and difficult to fully simulate complex geological conditions. (2) Numerical model of proppant migration in fractures based on similarity criteria. Numerical modeling software (such as CFD software) is relied upon to build mathematical models of proppant migration, and flow and deposition behavior of proppants in fractures are studied by modeling fluid dynamics, fracture geometry, and the like. The method can provide qualitative results, but the accuracy is limited by model assumption, and the method is complex in calculation and low in optimization efficiency.

However, the design process cannot be dynamically optimized, and real-time adjustment is difficult to realize, so that flexibility is lacking in the construction process, and complex changes cannot be dealt with.
