Abstract:

According to the exploration history in the northern Songliao basin, this paper summarizes the research results in different exploration stages and analyzes how the exploration idea in each stage changed and its role to exploring new targets. The Songliao basin went through three stages of oil and gas exploration: exploration of structural oil reservoirs (1955–1985), exploration of lithological oil reservoirs (1986–2010), and exploration of both conventional and unconventional oil and gas reservoirs (since 2011). The enlightment lies in objective geological conditions and the understanding of reservoir forming laws are the foundation for exploration deployment, sustainable theoretical innovation is the guarantee to make breakthroughs to oil and gas exploration, and technological innovation of engineering is the key to keeping steady increase of oil and gas reserves. The mature exploration areas in the basin are still primary exploration targets to discover large and medium-sized oil and gas fields in the future.

Key words: Songliao basin, structural oil reservoir, lithologic oil reservoir, unconventional oil reservoir, exploration history, important enlightenment, theoretical innovation, technological progress
