| 英文摘要 | The demand for a clean energy source from shale is growing day -to -day since it is not harmful to the environment like other fossil fuels. Further, shale reservoirs offer long-term geo-carbon dioxide (CO 2 ) storage. Innovations in horizontal drilling and multi-stage hydraulic fracturing have made shale gas extraction and geo-CO 2 storage economically viable. A three-dimensional Yanchang shale formation simulation model in Ordos ' s basin was developed using CMG-GEM, considering adsorption/desorption, diffusion, geomechanics, permeability changes, and non-Darcy flow. Two horizontally drilled wells, each 510 m long, were fractured and positioned 90 m apart. CO 2 gas was injected into Well-2, producing methane (CH 4 ) in Well-1. After simulation for 30 years, the cumulative mass of CH 4 produced was 1.07x10 +5 kg, the cumulative mass of CO 2 produced was 2.3x10 +4 kg, which is 1.14% of the mass injected, the cumulative mass of CO 2 injected was 2.01x10 +6 kg and cumulative mass of CO 2 gas stored was 1.987x10 +6 kg which is 98.86% of the injected mass of CO 2 gas. The natural fracture system was the dominant factor of enhanced shale gas recovery and CO 2 injection in the Yanchang shale formation. A sensitivity analysis was conducted with CMG-CMOST, examining the influence of reservoir and hydraulic fracture parameters in the storage of CO 2 and enhancing CH 4 recovery. Natural fracture porosity had the most significant impact on CH 4 production and CO 2 storage, followed by fracture permeability and half-length leading for hydraulic fracture parameters, with fracture conductivity being the least influential parameter. The approach used in this study applies to tight shale oil and gas formations in various sedimentary basins worldwide, enabling a more comprehensive understanding of reservoirs and hydraulic fracture parameters that can enhance oil and natural gas production. |
