Hydrocarbon expulsion potential of source rocks and its influence on the distribution of lacustrine tight oil reservoir, Middle Permian Lucaogou Formation, Jimsar Sag, Junggar Basin, Northwest China
文摘
The organic matter-rich Lucaogou formation has fair to good hydrocarbon-generative potential. Hydrocarbon expulsion began at 0.73% Ro and the peak expulsion occurred at 0.9% Ro. The total expelled hydrocarbon quantities are 18.7×108 t. The hydrocarbon expulsion intensity controls the distribution of tight oil.
