| Abstract: | Taking Well JY4 as example, the authors present petroleum system modeling with PetroMod software for shale gas resource assessment of Wufeng-Longmaxi shale in Jiaoshiba area, which takes account of hydrocarbon adsorption process within source rocks. On the basis of burial and thermal modeling, source rocks adsorption parameters obtained from isothermal adsorption of gas measurements were defined. The results show that the total gas content of Wufeng-Longmaxi shale is estimated in rang of 4.6–10.5 * 106 kg/km2, and the proportion of absorbed gas content is around 22–50% in Jiaoshiba area. |
