In the process of comprehensive research of oil and gas exploration and development, researchers need to use seismic geology comprehensive interpretation software (GeoSee) to carry out various research work. Among them, the collection and sorting of basic data requires a lot of energy, and there are problems such as time-consuming, low efficiency and prone to errors. The data channel module of GeoSee and exploration database based on QT development platform can automatically import the data in exploration database into GeoSee system according to business requirements, and be applied in various functional modules of GeoSee, providing comprehensive interpreters with intuitive, convenient and flexible data processing methods, which improves the work efficiency of comprehensive research of oil and gas exploration and development. In this paper, the design and implementation method of the data channel module based on QT establishes a complete set of application processes for data extraction, display and loading, and achieves good application results.
