Electronic detonators are widely used because of their advantages in real-time supervision of the whole life cycle (Zang, 2022). Due to the high requirements of the time difference synchronization between the electronic initiation system and the seismic wave recording system, the Electronic detonator has not been widely used for seismic exploration (Yang, 2020). This paper expounds the systematic and scientific test method from the aspects of the comprehensive performance of electronic detonators for exploration, the compatibility between the electronic detonator initiation system and the geophysical blasting machine system, the constraints of the geophysical explosion-related collaborative Danling managment cloud platform, and the quality of data collected by electronic detonator blasting in wells., and based on the analysis of the test results, the problems that need to be improved in the application of electronic detonators and detonation systems in the large-scale production of geophysical prospecting industry are put forward. .

The beach of the Shengli oilfield, as the prospect for steady continuous development of the Shengli oilfield, has a large area, special geographic and geological conditions, and other technical difficulties so that exploration has been slow. seismic acquisition methods in the beach area and very shallow water have been investigated and, with the introduction of new equipment, given rise to more sophisticated acquisition geometries. A series of improved seismic exploration methods in the beach area and very shallow water are established by analyzing different shot and receiver parameters. As a result, S/N ratio and resolution of seismic data have been improved significantly to identify subsurface structures, improve reservoir description, and increase reserves and production.
