| 英文摘要 | Because of the inherent complexity of shale reservoirs and pre-existing natural fractures (NF) and faults, an accurate characterization of hydraulic fracture propagations has not been well investigated. This paper proposed an integrated geoengineering method to comprehensively characterize the non-uniform fracture propagations in shale reservoirs, integrating high-quality threedimensional (3D) seismic, well-logging, experiments, and microseismicity. The results show that the Duvernay shale is strongly heterogeneous in petrophysics and geomechanics. The Duvernay shale reservoir is controlled by two phases of tectonics, resulting in the development of high-angle natural faults/fractures with average azimuths of NE18 degrees and SE115 degrees. Considering the coupling between NF as well as stress shadowing effects, a full hydro-mechanical coupling model for hydraulic fractures (HF) was developed and restrained by up to 25,000 microseismicity events. Simulated post-frac productivity conforms to the actual productivity by up to 87%, showing the robustness of the unconventional fracture model. The pre-existing faults should be recognized beforehand, and some mitigation strategies can be made to avoid hydraulic communications between hydraulic fractures and pre-existing faults, effectively developing unconventional shale resources. |
