  • Optimization of the particle size distribution of temporary plugging agent plays a key role in reservoir protection. An ideal packing model for temporary plugging agent particle size optimization was developed based on the Alfred Model, and a software was developed on the VB.NET platform. This software calculates the optimized particle size distribution using the parameters of the target formation. The relationship between binary and ternary particle size compatibility and filter loss was examined through PPT experiment, and the inverse correlation of the two was verified. Positive correlation between the degree of match and permeability recovery was verified through laboratory experiment on artificial cores of 0.38 μm2-0.42 μm2. Laboratory experiment showed that particle sizes optimized using the developed software effectively reduced reservoir damage, and the optimization results can be used in well completion and workover designs.
