【 摘 要 】

In this paper, the experimental methods and related explosion parameters calculation methods for liquid explosive explosion technology satisfying the explosion critical dimension of 2 mm are introduced. Studies have shown that the developed liquid medicine meets the needs of explosion reconstruction joints with seam crack width greater than 2 mm, it basically determined its formulation and performance optimization parameters. The detonation speed of 1500-3500m/s can be applied to the process test design requirements of different lithological characteristics; The safety and feasibility of on-site construction were verified by the horizontal well CZ44-58 process test application, which provided a reference for optimizing the performance design of liquid drug performance, which laid a foundation for the experimental application research of micro-crack explosion stimulation technology and technology in low permeability oil layer.
