In recent years, we have witnessed significant advancements in the exploration and development of unconventional oil and gas resources, such as shale oil and gas, volcanic rock oil and gas, and tight sandstone oil and gas, particularly in regions characterized by complex structures. The intricate geological conditions in these areas critically affect every phase of oil and gas development, from generation to preservation, making the accumulation processes for these resources increasingly complex and diverse. Consequently, researchers are encouraged not only to broaden their intellectual perspectives and nurture innovative ideas but also to master new theories and emerging technologies to tackle the exploration challenges these complex conditions present. Deepening our understanding of the accumulation rules in such environments is crucial; it enriches the theoretical oil and gas framework, fosters technological advancements, boosts reserves, supports the optimization of energy structures, and paves the way for sustainable energy development.
The research topic "Advances in Accumulation Conditions of Unconventional Oil and Gas Resources in Complicated Structure Areas" is dedicated to deeply exploring the cutting-edge of this field. It offers a platform to showcase the latest theories, methodologies, and insights, thereby advancing the geology of unconventional oil and gas and its practical applications. The goal of presenting academic papers under this theme is to elucidate the dynamic processes behind the accumulation of unconventional oil and gas during complex geological evolutions and to detail how different types of unconventional resources adhere to distinct and sometimes similar rules of accumulation. Moreover, this initiative promotes the application of the newest geological models and experimental techniques, contributing valuable insights to this field.
Potential topics of interest include, but are not limited to:
• Reservoir properties and primary controlling factors of buried hill igneous rocks;
• Enrichment mechanisms of shale gas amid significant transformation in complex tectonic regions;
• Mechanical properties of rock and crustal stress distribution within deep shale reservoirs;
• Characterization and evolutionary mechanisms of high-quality tight sandstone reservoirs;
• Conditions for the accumulation and preservation of unconventional oil and gas in complex structural environments;
• Sedimentary processes and diagenetic evolution in shale and tight sandstone.
