  • The main dynamic force driving the migration of Mesozoic hydrocarbons in the southern Ordos basin was mainly hydrostatic pressure in the upper part and differential compaction in the lower part. According to the dynamic characteristics, development of the hydrocarbon source and sealing conditions, four accumulation-forming dynamic systems may be distinguished:(1) the allogenic superpressure accumulation-forming dynamic system, (2) the autogenic superpressure accumulation-forming dynamic system, (3) the autogenic normal pressure accumulation-forming dynamic system, and (4) the allogenic normal pressure accumulation-forming dynamic system. Efforts should be intensified to carry out hydrocarbon exploration in the autogenic superpressure accumulation-forming dynamic system and autogenic normal pressure accumulation-forming dynamic system in the Zhenyuan-Jingchuan area, while in the Yijuan-Xunyi area the main hydrocarbon exploration targets are the allogenic superpressure accumulation-forming dynamic system and autogenic superpressure accumulation-forming dynamic system.
