Abstract In order to determine the geological resource of the upper gas reservoir of Wufeng Formation-Longmaxi Formation in Jiaoshiba block of Fuling shale gas field and evaluate the resource potential of the block, based on the high degree of exploration and the complete drilling data, the authors utilized the data of seven evaluation and horizontal wells to calculate the shale gas resource in upper gas layer of Wufeng Formation - Longmaxi Formation of the block by the static method. According to the requirement of geological industry standard Regulation of Shale Gas Resources/Reserves Estimation, the capacity method was used to calculate the geological resource of free gas, and the geological resource of absorbed gas was calculated by volume method. The authors explained emphatically the calculation method and various parameters, including the area, thickness, total porosity, free gas saturation, absorbed gas content, etc. The geological resource of the upper gas reservoir of Wufeng Formation-Longmaxi Formation in Jiaoshiba block of Fuling shale gas field was preliminary calculated. The results show that the geological resource is about 110 billion m³, and the resource abundance is about 0.4 billion m³/km². The grade of the shale gas resources is II-class, and there is a good development potential in the study area. This method is used to calculate and evaluate the resources of the Jiaoshiba block in Fuling shale gas field. The geological resource is obtained and the effect of the block is evaluated. The application of this method has good adaptability. This research is an important basis for the study of shale gas reserves producing situation in Jiaoshiba block.

Key words： Fuling shale gas field resources volume method capacity method parameters value
