GEOLOGIC CHARACTERISTICS AND EXPLORATION MEANING OF OIL-GAS-BEARING MICRO-BASIN
微型含油气盆地的基本地质特征及其勘探意义

The micro-basin thai can become a oil-gas-bearing basin must have four special geologic conditions at the same time. First of all. the micro-basin must be a deep depress in a long time during the period of the basin revolution. Second, the basin subsiding center and the depocenter ought 10 be the same place. Third, the fine sedimentary facies of the basin need to have a good fit sand to mud ratio. Fourth, the basin must keep a better close condition at the end ol revolution. Micro-basin research is a window to study macro-/middle-basin of oil and gas bearing. The aim of micro-basin research is work for macro-/ rniddle-basm exploration. So the micro-basin itself oil and gas exploration is the second in the micro-basin research.
