HEATING AND PRESSING SIMULATION EXPERIMENTS OF TYPICAL SOURCE ROCKS OF ZHU 1 DEPRESSION——DISCUSSION OF MODES OF HYDROCARBON GENERATION AND EXPELLATION AND TOC RECOVERY COEFFICIENTS
珠江口盆地珠-坳陷典型烃源岩热压模拟实验――生排烃模式及TOC恢复系数探讨

Heating and pressing simulation experiments of typical source rocks(type I-II_1,II_2 and III) of Zhu 1 depression are performed in the closed vacuum system.Peak stages of oil and gas generation and their generating ratios in different thermal evolvement stages have been studied.Also discussing modes of hydrocarbon generation and expellation,oil and gas affinity,hydrocarbon generation potential and TOC recovery coefficients of different source rocks in the different stages.The results of this paper provide the experimental basis and basic data to theidentification of the effective source rocks and evaluation of forming condition of oil reservoir in the prospective basin.
