- Abstract:
- Reservoir fractures have a significant effect on improving the physical property of tight sandstone reservoir, carbonate rock reservoir and unconventional low-permeability reservoir such as tight conglomerate rocks, igneous rocks and shale rocks. The researches on reservoir fracture were summarized, several methods of recognition and prediction on reservoir fracture were analyzed, and several key questions in reservoir fracture research were discussed. The results show that the recognition technology of reservoir fracture is a multi-division synthetic system composed with point (core and slices), line (logging), surface (similar surface outcrops), volume (seismic data) and time (dynamic production data); the qualitative prediction of reservoir fracture is mainly based on the relationship between fracture and structural location, lithology; the quantitative prediction methods contain inter-well direct interpolation, curvature, energy and rock failure (two-factor method), seismic, fractal dimension, tectonic stress field numerical simulation and multi-parameter criterion, etc.; each prediction method of reservoir fracture has its own advantage and disadvantage, thus the combination of multiple methods can realize the efficient prediction of reservoir fracture; the key questions of reservoir fracture research contain the fracture distribution prediction and elaborate characterization, fracture dynamic parameters and fracture 3D geological modeling. Finally, reservoir fracture prediction and modeling should be based on confirming the genesis, evolution and primary controlling factors of reservoir fracture in exploration and development of hydrocarbon fields.
