Abstract: Based on the indoor experiment of film hole single point source and single line interference infiltration, the authors analyze the rule of infiltration volume of film hole single point source and single line interference infiltration, study the relationship between the reduction volume and bilateral area and develop the infiltration model of film hole single line interference infiltration. The model with specific physical meaning and high calculation precision is proved to be efficient for calculating film hole unilateral interference infiltration. The research results laid a foundation for further research of film hole irrigation theory and technological parameters.
