Zusammenfassung:The invention belongs to the technical field of petroleum and natural gas fracturing, and particularly relates to a method for determining the migration velocity of a single-particle sinking agent. The method includes the steps that when the situation that the single-particle sinking agent is located in a deflecting section is judged, the inter-particle interference influence of other sinking agents in a well section on the migration velocity of the single-particle sinking agent is determined according to the number of particle sizes; according to the inter-particle interference influence, stress analysis is carried out on the single-particle sinking agent, and a migration equation of the single-particle sinking agent in the deflecting section is determined; and the migration equation of the single-particle sinking agent in the deflecting section is solved to obtain the migration velocity of the single-particle sinking agent in the deflecting section. According to the method for determining the migration velo
