They are the most practical areas for “secondary hydrocarbon-generation”, “secondary pool-formation” and “a second time adjustment and late-stage pool-formation”, and they are also the most favorable areas for “rapid pool-formation” and “many times adjustment and recent pool-formation”.

Hydrocarbon generation and reservoir formation:A case from Chang 7 source rock in Majiatan area,west margin of Ordos Basin;

Distribution characteristics,dominant factors of overpressure formation and their effects on the reservoir formation are systematicaly studied in this paper.

In this paper,three special mechanisms of reservoir formation are concerned: the pattern of oil displacement by the abnormal high pressure which is located along the faults;the pattern of oil migrating through the concordant faults which is located in traps' downdip direction;and the pattern of.
