BASIC CHARACTERISTICS OF OIL AND GAS BASINS IN CHINA

Oil and gas-bearing basins in China are grouped into three types: the tensional, compressional and transitional. The first type is dominant in the east, with the Songliao and the Bohai Gulf basin as its represe ntative; the second in the west, exemplified by the Tarim and Junggar basins; and the last in central China, represented by the Sichuan and Ordos basins. These petroliferous provinces are polycyclic superimpose d and composite basins, with complex traps of various origins and mega structural oil-gas belts.
