Abstract: The proposal of the Whole Petroleum System (WPS) theory has significantly enhanced the understanding of hydrocarbon accumulation theories, thus facilitating a series of major exploration breakthroughs in multiple basins in China. This study focuses on the hydrocarbon exploration and development in Junggar Basin, with an aim to further develop and refine the WPS theory and guide domestic and international oil and gas exploration and development. Initially, through analysis of new challenges posed by WPS to seismic exploration technology, the paper elaborates in detail on the research progress of seismic exploration technology and predicts its development trends. The research results show as follows. (1) The WPS theory poses three challenges to seismic exploration technology, i.e., achieving ultra-high shot and trace density acquisition and massive data processing, addressing the issue of coupling diverse target objects and multi-scale data, and enhancing seismic resolution and prediction accuracy. (2) During hydrocarbon exploration in Junggar Basin, four key technological breakthroughs have been achieved. Specifically, the seismic data acquisition technology has undergone a leap from conventional three-dimensional surveys to wide-band, wide-azimuth, and high-density nodal acquisition with high efficiency, the seismic data processing technology has further improved high-resolution, high-fidelity, and high-precision processing techniques, a basin-level high-precision seismic data platform has been established based on new seismic acquisition and processing technologies, and the progress in interpretation technologies such as discrete element numerical simulation, intelligent seismic facies characterization, multi-attribute interpretation of strike-slip faults, geological and engineering "sweet spot" reservoir prediction, and seismic-geological-engineering integration has provided new methods for studying the "tectonic system, sedimentary system, hydrocarbon transport system, accumulation system, and engineering support system" in WPS. (3) Three development trends in seismic technology for WPS exploration have been identified, i.e., seismic acquisition technology centered on ultra-high density, multi-wave and multi-component, seismic data processing technology promoted by the coordinated development of intelligent, high-performance computing and high-resolution imaging, and seismic interpretation technology with intelligent, quantitative, and dynamic characteristics.
