Abstract: In view of the insufficient utilization of residual gas reserves by primary well pattern development in Fuling Shale Gas Field, geology and engineering integrated stereoscopic development technology is the core means to improve gas recovery and achieve accurate utilization of residual gas reserves. As a result, a new high-efficiency shale gas development mode with geology and engineering integration has been established, and shale gas modeling and simulation integrated technology has been innovatively developed to conduct fine research and identify the distribution of residual shale gas; The coupling of geological and engineering double sweet spots enables to determine the gold target window of well drilling trajectory, and the classification standard system of “resource + stress + natural fracture” three-in-one layered benefit combination has been established; Based on the differential distribution pattern of residual gas, the drilling and fracturing optimization design process has been established with “geology-drilling-fracturing-surface collaborative optimization”; By using real-time monitoring, the dynamic adjustment of well drilling trajectory and fracturing construction has been conducted, and integrated data sharing platform and real-time decision system have been constructed. The geology and engineering integrated stereoscopic development technology has guided the development of Jiaoshiba block and increased estimated recovery rate from 12.6% to 23.3%, and up to 39.2% in the stereoscopic development zone. The application of this technology supports to reduce shale gas drilling and production investment, and billion square meter production capacity construction investment and development costs year by year, which effectively guides the recovery enhancement and high-efficiency development of Fuling Shale Gas Field.
