Gas Generation Potential of Permian Oil-Prone Source Rocks and Natural Gas Exploration Potential in the Junggar Basin, NW China

The Junggar Basin, where twenty-seven oil fields and five gas have been discovered, is a typical “oil basin” with proven ratio of natural 5.3%. amount from Permian source rocks has found in the western margin basin, but no large-scale reservoir discovered. key to exploration whether oil-prone large generation potential. Based on comprehensive analysis geochemical features hydrocarbon simulation experiments, it proved that intensity could meet standard medium gas-fields (20 × 108 m3/km2) at depth more than 6500 m. In Penyijing Shawan Sags, burial Fengcheng Formation between 8500 m 10,000 m, respectively. It be concluded Penyijingxi Sags relative higher addition high potential, two sets effective reservoirs (wreathing volcanic secondary dissolution sandy conglomerates) thick caprocks overpressure are developed most areas Basin. Recently, discovered industrial had obtained around Sag, Southern Our research results practice show Basin relatively
