Abstract: Well Puluye1(PLY1), the continental shale gas risk well, has obtained a high industrial natural gas production of 10.4×10⁴m³/d in the semi-deep lacustrine subfacies shale gas reservoir of the Jurassic Qianfoya Formation in Puguang gas field, Sichuan Basin, and also stable natural gas yield of 6.0×10⁴m³/d in the pilot production stage, achieving a major breakthrough in the exploration of continental shale gas in Qianfoya Formation, Sichuan Basin. Based on the systematic coring and testing results of Well PLY1 and the comparative analysis of understandings in research of the same formations in the whole basin, the paper explores the main controlling factors and models for the enrichment of Jurassic shale oil and gas, and points out the key exploration directions of Jurassic shale gas in Sichuan Basin. Through basin-mountain coupled formation correlation, boundary identification and formation division, and systematic coring and anchoring in work area, the transition (from depressional lake basin to foreland basin)of basin properties in the Early-Middle Jurassic has been clarified; under the reservoir pattern of gas in the north and oil in the south, the Middle Jurassic Qianfoya Formation develops a "double complex" type unconventional oil-gas box; a binary differential enrichment model of continental shale oil and gas in the foreland basin has been established, and it is particularly pointed out that the north area of Tongjiang-Puguang-Kaixian (Tongjiang gas generating center)is a strategic block for the exploration and development of Jurassic continental shale gas, possessing the hydrocarbon resource of 3.3×10¹²m³. Based on the exploration practice, it is preliminarily proposed that the hydrocarbon generation pattern of lacustrine exinite-rich shale in Qianfoya Formation of Sichuan Basin is still be in oil-gas generation window when vitrinite reflectance(R_o) is over 2.0 %, and 0.7 % ≤R_o≤2.2 % indicates the real field of continental shale oil-gas exploration, which greatly expands the exploration space of continental shale oil and gas.
