HYDROCARBON-GENERATION HISTORY OF FAULT SUBSIDENCE-DEPRESSION PROTOTYPE SUPERIMPOSITION SYSTEM：A CASE STUDY OF QINTONG SAG IN THE NORTH JIANGSU BASIN

The hydrocarbon-generation history of the oil and gas materials in a fault subsidence-depression basin is certainly restricted and controlled by the burial history of fault subsidence-depression prototype superimposition.The idea of petroleum reservoir-forming from hydrocarbon source rock to trap must be brought into the basin system.Based on this idea,the relationship between geologic process and its response in a basin can be determined,and the boundary conditions that the prototype controls the dynamic changes of pressure(P),volume(V) and temperature(T) are established.At the same time,the TSM basin modelling system is used so as to calculate the hydrocarbon-generation quantity and analyze the hydrocarbon-generation history.
