Abstract: According to present situation of exploration, the cause of formation of basins and age of production horizons, oil-bearing basins in China's continent can be divided into a longitudinal zone composed of the Yilan-Yitong-Bohaiwan-Jianghan group of basins and a latitudinal zone composed of the Junggar-Erlian-Songliao group of basins.These two zones contain 94% of the general output and 99% of the general reserves of China's petroleum, so we call them the longitudinal and latitudinal petroleum rich "golden zones".Based on evolution of China's plate tectonics, tectonic setting of basins, and conditions for oil-pool formation, this paper analyses the general and individual characteristics of the longitudinal and latitudinal petroleum-rich zones (contrasts them with two kinds three types oil-gas tectonic units) and concludes that the latitudinal zone has the most advantageous prospects for petroleum exploration.We therefore suggest that this latitudinal zone be considered the principal region for petroleum exploration in continental China within this zone, exploration should especially be strengthened in the Jungger basin, where may be discovered an especially huge oil field.
