| description | The shale quality characteristics such as lithofacies, geochemistry, porosity and gas bearing properties, some evaluation standards of gas bearing properties and compressibility of the upper gas layer were studied for the upper gas reservoir of Jiaoshiba block in the Fuling Shale Gas Field. The upper gas layer in Jiaoshiba block is mainly of type Ⅱ, and the layer No. 8 has the best gas bearing properties. of five catogaries including shale hydrocarbon source quality, gas bearing capacity, structural deformation strength, fracture and buried depth were optimized, and an evaluation system for development selection of the upper gas reservoir in Jiaoshiba block was established. The upper gas reservoir in Jiaoshiba block was divided into four areas, among which the well block JY-A is the most favorable area, which can be considered to be a standard for gas reservoir development in the upper part of Jiaoshiba block. In addition, the study revealed that organic matter abundance, porosity and preservation conditions are the main factors affecting shale gas enrichment in the upper gas layer of Jiaoshiba block, while burial depth, crustal stress and the extent of natural fracture development are the main factors controlling gas well production in the upper gas reservoir. |
